Learn HTML and CSS: Focus, contrast and labels

Accessible

Rosa comes to the repair café too. Her eyesight is poor and she doesn't use a mouse, but works with the keyboard and a screen reader. Walter wants her to sign up just as easily as anyone else.

For everyone

Whoever works with the keyboard jumps from field to field with Tab and has to see where they are: the focus. Never take that ring away without putting something in its place. With :focus-visible you give a clear ring that only appears when someone works with the keyboard.

Contrast: text has to differ enough from its background. The guideline for ordinary text is a ratio of at least 4.5 to 1. Light grey on white doesn't make it.

And every field gets a label, as in lesson 6. Tap a field in the page: the yellow ring shows where you are.

style.css

1input:focus-visible,2button:focus-visible {3  outline: 3px solid #ffd166;4  outline-offset: 2px;5}

Try it yourself

Give the fields and the button a yellow ring on keyboard focus, outline: 3px solid #ffd166, with outline-offset: 2px. Without focus there's no ring.

Contrast: text has to differ enough from its background. The guideline for ordinary text is a ratio of at least 4.5 to 1. Light grey on white doesn't make it.

And every field gets a label, as in lesson 6. Tap a field in the page: the yellow ring shows where you are.
