:interest-target

Syntax

:interest-target {
  /* ... */
}

Examples

Selecting the target element associated with an interest invoker

In this example, we demonstrate how :interest-target can be used to apply styles to an interest invoker element's target element when interest is shown on the invoker.

HTML

The markup includes a <button> and a <p>. We specify the <button> as an interest invoker by giving it the interestfor attribute whose value matches the id of the <p> element, making the paragraph the target element.

<button interestfor="mytarget">Button</button>
<p id="mytarget">A paragraph</p>

CSS

In the CSS, we specify a rule with an :interest-target selector, which will apply a specific set of sttyles to the <p> element when interest is shown in the <button>. We also apply some other styles to the <button>, which we've hidden for brevity.

body {
  margin: 10px;
}

button {
  padding: 5px 10px;
  border: 1px solid #ddd;
  border-radius: 5px;
  background-color: #eee;

  cursor: pointer;
}

p:interest-target {
  font-size: 1.5em;
  font-family: sans-serif;
  padding: 10px;
  background-color: hotpink;
  color: purple;
}

Result

This renders as follows:

Try showing interest in the button (for example, by hovering or focusing it), and note how this results in the styles shown earlier being applied to the paragraph.
