Firefox 57, also known as Firefox Quantum, will be released on November 14. It will bring some significant changes to the Firefox rendering engine to improve performance and open the door for more new features in the future. Here is what you need to know if you are a user of the NVDA screen reader. Continue readingAlso on:
As you may or may not have heard, Firefox 49 supports the HTML5 <details> and <summary> elements. Both full keyboard support and support for assistive technologies is also available right from the start.
What are they?
<details> and <summary> allow to dynamically show and hide blocks of content. For example, when composing a list of frequently asked questions, each question could be wrapped in an details-summary-block, with the summary being the question, and the details following in the rest of the details block. The user can then show and hide the details by just clicking or pressing on the summary content.
Well, no more, as the HTML5 specification addresses these issues with the <details> and <summary> elements.
This can be very easily demonstrated. Navigate to the below heading, which is going to be announced by screen readers as a button, with a collapsed state, and then press Space, or use the mouse or your finger (when on a touch screen) to click or press on it. Then, the button will change to an expanded one, and there will be another new paragraph below that heading. You can press on the button again to collapse that paragraph again and make it disappear.
Press me to show what I’m wearing underneath
Hahah, thought you’d find something naughty here, eh? Well, sorry to disappoint, it’s just a silly rambling of mine. Go ahead and go back up to close me again.
The code for this is pasted below.
<details><summary><h3>Press me to show what I'm wearing underneath</h3></summary> <p>Hahah, thought you'd find something naughty here, eh? Well, sorry to disappoint, it's just a silly rambling of mine. Go ahead and go back up to close me again.</p></details>
The content inside the <details> element can be all kinds of elements like lists, tables, sub headings if need be etc. Just remember to keep the proper heading structure when you do it. The fact that I used a heading up there is totally optional, too. It just fits in the heading structure of the blog.
Hope these elements will now help to create more accessible collapsible content blocks! Other browsers like Chrome and Safari also support these elements, and we’re hoping that Microsoft Edge will follow lead soon as well!
A few months ago, I wrote about the efforts to make the built-in Firefox developer tools more accessible. That work started in January and is now carrying first far-reaching fruits. Here’s an update! Continue readingAlso on:
