Styling a parent element when it is in focus using CSS3

Is there a way to apply a style to the parent element when an input is in focus?

input:focus
{ 
  background-color:yellow;
}

For example, if we have the following HTML:

<div class="foo">
      <input type="text />
      Hello
</div>

Is it possible to change the style of the "foo" div when the input field is focused?

edit: This question may be related to Affecting parent element of :focus'd element (pure CSS+HTML preferred)

Could someone provide an explanation on how this can be achieved?

htmlcss

Answer №1

Currently, CSS does not have a parent selector available. However, you can achieve this using jQuery:

HTML

<div class="parent">
    <input type="text" />
</div>

CSS

.parent {
    /* styles for the parent */
}
.parent.active {
    /* apply styles when the input is hovered */
}

JavaScript

// Add a class to the parent element when the input is focused
$('input').on('focus', function () {
    $(this).parent().addClass('active');
});

Here is an example on JSFiddle

Answer №2

Unfortunately, CSS does not support a parent selector feature, which means you cannot apply styling to a parent element based on actions of its child elements like hovering. In such cases, utilizing JavaScript is necessary.
