A11y tips: hide elements for all users
To hide content for all users (sighted, screen reader and keyboard) there are several techniques that we can use with some differences between them:
HTML attribute hidden
The item and everything it contains is removed from view for the user, from the accessibility tree, and from the tab order. It's as if it doesn't exist in HTML: you can't see it, the screen reader doesn't announce anything, and you can't tab to it.
<div hidden> <p>This content won't be shown</p></div>
CSS display: none
It has the same effect as the previous one, with the only difference that here we need the CSS to be loaded so that the element is hidden, while with the hidden
attribute the element will never be shown no matter there is CSS.
<div style="display: none;"> <p>This content won't be shown</p></div>
CSS visibility: hidden
The effect is the same as the previous ones with the difference that here the element is hidden from sighted users but maintaining its dimensions (width
and height
), with which an empty space appears that does not show anything, neither the element nor its content.
<div style="visibility: hidden;"> <p>This content won't be shown but it'll take up space</p></div>
