"Customised radio buttons and checkboxes are a common design pattern found on the web, and it doesn't take too much to ensure that your beautifully designed toggles are still navigable via keyboard."

There are various techniques to visually hide content in our web interfaces, but are you aware of the different effects they have on the accessibility of that content? While it would be nice if there was a single, native, solution for hiding content, there are contextual benefits to the various techniques at our disposal. Since there have been many articles already written about these techniques, over the many years they've been in use, the focus of this article will be to highlight the ones that are most appropriate for modern web development. We won't just look at the code behind each of these techniques, instead we'll focus on why each technique has its place, using practical examples to demonstrate their purposes. But before we talk about how to hide content we should ask ourselves a question… Why are we hiding content?

"When I found out the major browsers were beginning to include error validation into their support for forms, I was pretty excited. Form validation is always a fiddly part of accessibility, so I'm always looking out for ways to make it easier for developers to do properly. I read MDN's form data validation tutorial and a CSS Tricks article on client-side form validation and immediately made some test forms. Sadly, I was disappointed with the results. The default error validation in browsers is almost completely inaccessible. I was hoping we'd get default "you've forgotten to fill this in" messages that could be customised. I might have been a bit too optimistic! Validation at the browser level has many of the same issues we find at the website level."
