? Tip of the Week

Using :focus-within to highlight a form

If you’re working on a form with multiple sections, then the :focus-within property may prove useful.

This CSS pseudo-class can be utilised to highlight an entire form area when the user selects any of a form container’s input fields.

The example image below demonstrates this (you can also see it in action in this little CodePen demo). The user has selected the Name input, and the entire form is highlighted in green:

Using this property is simple enough — just append the :focus-within selector on to the element you wish to highlight. Then, when any of the elements descendants are bought into focused, the desired change will occur.

form:focus-within { background: #98FB98; }

Browser support for this currently sits at around 82% — IE, Edge and Samsung Internet are amonst those yet to implement support.
