Here Is How You Build an Accessible Website With Drupal 8

Here Is How You Build an Accessible Website With Drupal 8

by Adrian Ababei on Jan 11 2017
"Barrier-free access” is carved within the very “DNA” of Internet itself. Therefore, your site, too, should be accessible first and foremost!
 
Before you even start to make it visually-arresting and useful. Before you even consider how you could add value to your website visitors' lives!
 
What started as an accessibility-focused initiative in Drupal 7, or better said "as an attempt” to comply with World Wide Web Consortium guidelines, has gradually evolved into a powerful set of accessibility-oriented features in Drupal 8.
 
Bugs have been addressed, “old” features improved, new enhancements and new features added in Drupal 8 to boost its accessibility in core.
 
Now let's stop “beating around the bush” and put the facts on the table!
 
Let us enlist and detail to you these particular accessibility-enhancing features in Drupal 8 that will make your job (building an accessible website) easier than never before:

 

1. Improved Contrasts

 
Empathize with those future visitors suffering from colorblindness, then try simulating a context where users would access your website (from their mobile devices) in bright sunlight.
 
Optimal contrast will “send” an invitation to the users in the above real-life scenarios to keep clicking/scrolling and thus prolonging their visits on your Drupal site. 
 
The great news is that Drupal 8's accessibility maintainers have tackled the contrasts' issue and made the necessary improvements.

 

2. Controlled Tab Order 

 
It was just yesterday, in our previews post, that we talked about the importance of “blazing your users' path” to the information they're searching for on your website. About easing their “search” with the right UX elements.
 
Well, this accessibility-boosting feature, in Drupal 8, serves the same purpose. 
 
The Tabbing Manager Javascrip feature is that “flashlight” which will point out the main elements on your website to your visually-impaired or non-mouse visitors.
 
And this enhancement will make all the difference for them!
 
Just think about the time and energy that these visitors save by quickly scanning through your tabs instead of striving to navigate through a complex, crowded user interface relying entirely on screen readers!
 
Zero confusion leads to zero frustrations and to a better user experience for your website's visitors. And this is gold in the age of user experience, right?

 

3. Inline Form Errors

 
And this is a truly notable enhancement, which proves that we have come a long way from Drupal 7 when it comes to the support for accessibility available in Drupal 8's core modules.
 
If in Drupal 7 errors made when users filled in a web form appeared on top of that specific form, while fields got colored in red, as a “warning” sign (not exactly the most effective solution for the visually impaired users), Drupal 8 comes to your rescue with its form inline errors.
 
In this version of Drupal errors icons get displayed next to the specific fields of the form.
 
A much needed improvement, wouldn't you agree?
 
Note: still, the Form Inline Error is an optional Core module, therefore it needs enabling first.

 

4. Fieldsets for Radios and Checkboxes

 
When it comes to the Form Api, here's another great enhancement that Drupal's accessibility maintainers “spoil” you with: fieldsets for checkboxex and radios.
 
Just imagine how this improvement will ease screen readers' (and implicitly non-visual users relying on them) otherwise not at all easy “job” to parse complex forms.
 
Since related elements get grouped together in Drupal 8, it now becomes a lot easier for you (or your team of Toronto developers) to enhance forms in Drupal.

 

5. Alternative Texts for Images

 
Visually-arresting photography and stunning imagery cannot “wow” your visually impaired visitors. 
 
Still, Drupal 8 lends you a hand for helping your users “visualize” and thus “bend before your talent” (or your web designers' talent).

How? With its alternative text for image feature.
 
It's now a required field in Drupal 8, by default: you type in short descriptive text so that all users, without any discrimination, can imagine those visually-arresting images that you'll upload on your website.

 

6. More Semantics

 
Semantics! The ultimate impediment that any initiative aimed at enhancing accessibility on your site needs to overcome.
 
No wonder that one of the ultimate goals of Drupal 8 core maintainers was to “add more meaning to the code”. To enrich Drupal with more semantic HTML elements for the assistive technology to be able to interpret.
 
And here are the achievements of all the sustained efforts in this direction:

 
  • WAI-ARIA landmarks in core (a major step forward)

     
  • live regions

     
  • roles & properties  
 
Now to name just one example of what “more semantics” in Drupal 8 means, when it comes to accessibility: now screen readers can easily interpret pieces of code such as  <footer>, <header> or <form>. 
 

7. Tables and Views

 
Speaking of improved semantics, note that the views tables markup is more semantic in Drupal 8.
 
Let's shed some light on this feature:

 
  • it enables you to explain the purpose of a particular table on your website through a <caption> element

     
  • it enables you to add a quick “summary” explaining which is the best way to navigate the table and how the data included there is structured; and all this by using the <summary> element

     
  • it enables you to use “id” and “headers” attributes and thus associate data cells with header cells

     
  • it enables you to “play with” the “scope” attribute, thus to mark your tables' column and row headings

     

8. Aural Alerts 

 
Animations, color changes, specific text and so on: how do you make visual updates accessible for all users? Even to those relying exclusively on screen readers as intermediates for accessing content on your website?
 
You rely on Drupal 8's Drupal.announce().
 
This JavaScript method creates an “aria-live” element on the page enabling instructions to be read to these specific visitors on your site either as assertive or as polite.

 

9. Hidden Elements 

 
An alternative to CSS styling “display:none” was greatly needed, since this one makes elements invisible both to visual and non-visual users.
 
And hiding them from everyone is no web developer's (or website owner's) intention!
 
Therefore, the team “responsible” for Drupal 8's accessibility decided to enable future Drupal users to rely on 3 different classes for hiding certain elements:
 
  • “hidden”: for hiding an element from all the visitors on your site
  • “visually-hidden”: for hiding an element from your website's visitors, but keeping it “visible” for screen readers 
  • “invisible”: for hiding an element both from the visitors and from screen readers, without influencing your site's layout

     

10. CKEditor WYSIWYG Accessibility

 
CKEditor, too, has been greatly improved in Drupal 8 in the name of empowering users, like you, to generate accessible content on their Drupal websites!
 
Here are its significant improvements:

 
  • the WYSIWYG editor's been upgraded with keyboard shortcuts (for which all those keyboard-only users and power users on your site will “thank you” for)

     
  • more semantic elements have been added: for instance HTML 5 tags which enable you to add captions to images

     
  • a language toolbar button has been added, enabling screen readers to select the appropriate language for each content 

     
  • an accessibility checker plugin is now available for CKEditor
 
And this is precisely how Drupal 8 empowers you to build barrier-free websites that say “welcome” to all visitors, both visual and non-visual! 
 
What do you think of these improvements and new features in Drupal 8?
 
To what extent do you consider that they'll ease (or have they already?) your job as a Drupal web developer/Drupal website owner?

Is Drupal Good for eCommerce? 11 Excellent Reasons Why You’d Choose It over Another Platform
"... wanna run eCommerce on Drupal 8 but don't know if it's a good idea." But is Drupal good for eCommerce?  And, most of all: Is it better suited for your own online business needs and feature requirements than other eCommerce platforms out there? Some legitimate questions you're struggling with there… To give you a hand, here's a list of 11 excellent reasons why you'd lean towards Drupal for your next eCommerce project. Reason #1: You're in Full Control of the Source Code to Make Any Changes You Want In other words, you don't need to convince vendor first that the changes you need to make are beneficial for him/her. You're free to extend Drupal eCommerce platform's core functionality, to adapt, and extend its code till it meets your needs entirely.  … till it integrates perfectly into that specific software that you use. Which is not the case when you go for a commercial solution: you're not granted access to the core code for any custom software development work that you might need to make. Of course, this "reason" becomes a really strong selling point only if/when: you have non-standard business requirements it's a large, complex eCommerce website that you're building Reason #2: Your eStore Grows With Drupal  Drupal scales with your business... effectively. And by that I mean that it's designed to keep the resources and the time required to handle your online store's growth at a minimum. Being: flexible by nature (its open source nature) powered by the API-first initiative … the Drupal 8 eCommerce platform makes the best choice if "scalability" is on top of your list of requirements. Reason #3: You Get to Reach Out to Your Customers Across Multiple Channels  "Is Drupal good for eCommerce?" It becomes the perfect option for your own eCommerce website if you're planning to reach out to your customers across an entire network of sales channels. Let's say you have your main/central eCommerce website and you need to pull content from there and to distribute it across a whole ecosystem of channels — eCommerce apps, digital kiosks, conversational interfaces — and devices. Then, the API-first initiative allows you to tap into a headless commerce Drupal architecture and: use Drupal as a back-end content repository configure your content to fit all types of formats and reuse it whenever (and wherever) needed increase your outreach incorporate business automation into your development team's workflow: help them work smart and achieve more Reason #4: You Get to Deliver Content-Driven eCommerce Experiences With Drupal, you get the best of both worlds: an eCommerce platform (by integrating one of its specialized eCommerce modules into the content management system) a content platform And this is what makes it ideal for: tapping into the experience-led eCommerce model getting the most out of your content marketing efforts (think blog posts, effectively interconnected product pages, user guides, etc.) Reason #5: You're Free to Integrate Any Third-Party Service into Your Online Store From: marketing platforms to analytics services to payment gateways of your choice (there are 80+ payment options available with Drupal Commerce) to third-party add-ons that would automate your team's tasks and boost their productivity (while boosting online sales, as well) … Drupal &amp; its eCommerce component accommodates any type of integrations you need to make. Reason #6: "Is Drupal Good for eCommerce?" It Is for Delivering High-Speed eCommerce Experiences Just think… real-time shopping cart updates.  Or pretty much any action that your customers would need to carry out on your eCommerce site, then turbocharge it with top speed. A decoupled Drupal Commerce setup (add the JavaScript framework of your choice here) enables you to deliver such type of dynamic user experiences.  Reason #7: You Have No Limits to How Much You Can Extend Your Drupal 8 eCommerce Website Drupal Commerce can grow as much as your business needs. Whether you need to integrate: a whole network of third-party systems a whole lot of contributed modules an eCommerce Drupal distribution (a bundle of multiple modules) a Drupal eCommerce theme  … and extend your eCommerce store's functionality, there's no limit to what you can incorporate into your Drupal eCommerce website. Reason #9:  You Benefit from an Extremely Configurable eCommerce Solution "Whereas eCommerce solutions are often developed with an application mindset, highlighting what you can do with it out of the box, Drupal Commerce was developed with a framework mindset, focusing on what you can build with it." (Source: Drupal.org) Basically, you're free to customize every little piece of your Drupal 8 eCommerce site, till it: delivers that unique shopping experience you want it to meets all your ultra-personalized requirements: to trigger certain actions based on user input, to display multiple tax rates, to have an out-of-the-ordinary checkout flow, etc. Here, it's up to you and it depends on what you need to build: Are you looking for a cookie-cutter eCommerce solution, that would help you get a generic webshop up and running in no time? Or do you want unlimited customization freedom, that comes at the cost of…  investing more time in writing custom code? Reason #10: You're Free to Sell Both Physical and Digital Goods And that thanks to Drupal Commerce's flexibility: It provides you with the functionality you need to start selling your digital products — subscriptions, tickets, online courses, etc. — on your online store. A key aspect to consider when comparing the features of your best options in terms of eCommerce platforms in 2020. Reason #11: You Can Make the Most of the Granular and Differential Access to Content Drupal allows you to define different roles for your team members and to assign several levels of permission to each role. Not everyone would then be authorized to edit content, add products, manage orders, publish content, etc. This way you get to: set up a convenient hierarchy harden your online store's security  So, Is Drupal Good for eCommerce? Maybe a more appropriate question would be: "Is Drupal the right solution for my eCommerce business?"  It might be... And these 11 reasons mentioned here do become the best arguments for you to choose it over another platform (Ubercart, Prestashop, Shopify…) if: it's a growing or an already established eCommerce business that you run (otherwise, all that configuration and custom work might be an overkill for a small business) you have complex feature needs for your online store: you need to integrate it with coupon rules, several backend systems, and so on Do you fit the eCommerce business owner "profile"? For we do fit the profile of that Drupal eCommerce agency you're looking for, capable to tweak it till it fits your complex requirements to the slightest detail.

10 Best Headless CMS in 2020, That Cover Most of Your Requirements (Part 1)
Overwhelmed with options? Are you building your first (e-commerce) headless CMS and you don't know what headless CMS platform to choose?  What are the best headless CMS in 2020, so you can at least narrow down your choices and start... somewhere? Which system matches most of your feature requirements? Here's a top 10: 1. But First: What Is a Headless CMS, More Precisely? Relax, I won't bore you with too many details — we already have an in-depth post on the differences between headless and traditional CMS. So, if we were to sum up the concept in just a few words, we could say that: A headless content management system is an architecture where content is separated from the presentation layer (the client-side front-end). Meaning that you get to create, store, and edit "raw" content (with no design or layout) in the backend and deliver it wherever needed —wearable, mobile app, website — via API. In short, what you get in a headless architecture is: a database to store your content in a dashboard for editing your content Source: Zesty.io As for the "head" that serves your content to the end-user : you're free to build your own front-end, from the ground up … and even multiple front-ends, if needed, that will all use calls from the API to retrieve and display content 2. … Then What's a Decoupled CMS? Headless CMS vs decoupled CMS: what's the difference? And why headless over decoupled? The role that the API plays… That's what makes the difference (and why you'd want to go for a headless approach): If, in a decoupled architecture, the API plays the role of an intermediary between back-end and front end, in a headless architecture the API can be used by any of the front-end portions for pulling data. In other words, a decoupled CMS does come with a built-in front-end delivery layer, that you can rely on, but a headless approach is an API-driven content repository. Which gives you more flexibility for delivering content to any type of display layer. … to multiple "heads". You're free to distribute it wherever it needs to get displayed. 3. Why Choose a Headless CMS? Top 9 Benefits Before I "divulge" the best headless CMS in 2020 to you, here's a shortlist of the key advantages of using a headless CMS software: you get to engage your customers with personalized content across an entire network of digital channels, at different stages in their journey you can deliver richer digital experience, tailored to each channel you gain platform independence you're free to choose your technology of choice you benefit from cross-platform support you get to manage your content from a central location and distribute it to multiple platforms/IoT-connected devices, in a universal format you're free to manage all your platforms from one interface your development team gets to choose the development framework of their choice, integrate new technologies and, overall… innovate you're free to redesign as often as you need to, without the dread of re-implementing your entire CMS from the ground up     4. … And When Should You Use It? 5 Best Use Cases  How do you know for sure that you need to adopt this approach? You know it because your scenario describes one of the following use cases for headless CMS: you're building a site using a technology you're familiar with you're building a website with a static site generator you're building a JS-based website or web app you're building a native mobile app you're building an e-commerce site and you know that the commerce platform you're using won't… cut the mustard as a CMS; or you need to enrich product info in your online store 5. What Are the Best Headless CMS in 2020? Top 10 "Which CMS should I use?" you wonder. "The one that meets most of your requirements…" So, you should start by pinning them down. What features are you looking for in a CMS? Maybe you need a system that should: be straightforward and easy to use for the marketers/non-technical people in your team be built on… Node be highly customizable and editable for your content team to be able to change overlay text, logo, background video/image be simple to set up integrate easily with Gatsby support multi-site setups not be tied up to (just) one specific database provide ease of content entry and rich-text support provide a granular permission system provide native support for content types What are the features that your project couldn't live without? Now, with that list of "mandatory" features at hand, just drill down through your top headless CMS options in 2020. Here they are: 5.1. Storyblok A purely headless CMS that ships with a visual editor, as well. Why would you go for Storyblok? What makes it one of the best headless CMS in 2020? it provides the experience of a page builder for all those non-technical users in your team: editors get to manage content via a more user-friendly interface it grants your developers easy access to the APIs they need 5.2. Prismic Its major selling point? It allows you to choose your own language, framework, technology… And these are the 3 good reasons to go with Prismic as your headless CMS: it allows you to model your content schema and to add your content you're free to choose whatever framework that meets your feature needs: React, Vue, Next, Nuxt, Node, Gatsby… you're free to choose either GraphQL or RESTful API to query content 5.3. Drupal 8 Headless CMS   Another great option is to exploit Drupal's headless capabilities and pair them with the JavaScript framework of your choice. Here are some of the best reasons why you'd use a Drupal 8 API-first architecture: Drupal's a mature and enterprise-level headless solution backed by a wide community, used by more than 1 million sites globally; you get to tap into its massive module collection and even create new custom ones to extend your website's functionality its JSON:API follows the JSON:API specification; developers in your team can start using the API even if they're not experts in working with Drupal you get to load your GraphQl schemas straight from your Drupal content repository; there's a specialized module for this: the GraphQL module you get to use all of  Drupal's famed features (granular access to content, processes, workflows, modules, etc.) right away; you get them out-of-the-box since the REST API is… rooted deep into Drupal 5.4. Strapi, One of the Best headless CMS for Gatsby. It's an open-source Node.js headless CMS, a "host it yourself" one, that allows you to build Node.js apps in… minutes. Why would you use it? because it generates available RESTful API or uses GraphQL shortly after installation, making data available via customizable API because it allows your developers to invest all their resources in writing reusable app logic (instead of having to use some of that time to build an infrastructure) because it's fully JavaScript because it supports plugins that extend the platform's functionality because it's open-source: you'll find the entire codebase on GitHub  5.5. Contentful  Looking for a platform-agnostic solution? A… content delivery network that would enable your development team to manage and distribute (and reuse) content to multiple channels? Then this is the API-driven headless CMS you're looking for. Here are 6 other reasons why you'd want to put Contentful on your shortlist: consistent APIs easy to set up you're free to create your own models easy to use: ships with a robust, non-technical, user-friendly UI you get to add custom plugins quick and easy you get to set your own schemas to get displayed the way you want them to, across different apps Good to know! There's even a Shopify extension available. What it does is connect your online store to your content, stored in Contentful. And if you'll need help with building, fine-tuning, and integrating your content hub, we're ready to tweak Contentful to your needs.  END of Part 1!
