Six steps that everyone can do to catch accessibility gotchas:
- Check image descriptions
- Disable all styles
- Validate HTML
- Check the document outline
- Grayscale mode
- Use the keyboard
Some excellent explanations for these five pieces of sensible typography advice:
- Set your base font size in relative units
- Check the colour of your type and only then its contrast
- Use highly legible fonts
- Shape your paragraphs well
- Correctly use the heading levels
A deep dive with good advice on using—and labelling—sectioning content in HTML: nav, aside, section, and article.
I encourage you to think about and make sure you are using the right elements at the right time. Sometimes I overthink this, but that’s because it’s that important to me - I want to make sure that the markup I use helps people understand the content, and doesn’t hinder them.
Patrick is thinking through a way to implement :focus-visible that’s forwards and backwards compatible.
Jake is absolutely spot-on here. There’s been a lot of excited talk about adding an h element to HTML but it all seems to miss the question of why the currently-specced outline algorithm hasn’t been implemented.
This is a common mistake in standards discussion — a mistake I’ve made many times before. You cannot compare the current state of things, beholden to reality, with a utopian implementation of some currently non-existent thing.
If you’re proposing something almost identical to something that failed, you better know why your proposal will succeed where the other didn’t.
Jake rightly points out that the first step isn’t to propose a whole new element; it’s to ask “Why haven’t browsers implemented the outline for sectioned headings?”
(I added a small historical note in the comments pointing to the first occurrence of this proposal way back in 1991.)
A good explanation of HTML5’s sectioning content and outline algorithm.
A brave attempt to explain the new outline algorithm in HTML (although it inaccurately states that no browsers have support for it—Firefox shipped with it a while back).
You can safely skip the comments: most of them are discouraging, ignorant, and frankly, just plain stupid.
Mike takes on the very tricky task of explaining the new outline algorithm—definitely one of the hardest features of HTML5 to explain, in my opinion.
A very handy tool to help you check the outline algorithm in HTML5.
