Is it possible to change the page background when hovering over a a using only CSS? I am searching for a solution that does not involve any JavaScript.
I understand that we can access child elements with CSS, but I am unsure if it is possible to target the body element in this scenario. Any suggestions?
Check out this DEMO
Take a look at the html snippet below:
<a href="">link 1</a>
And here is the css portion:
body {
background: lightblue;
}
a:hover:before {
content: '';
position: fixed;
display: block;
top: 0; bottom: 0; left: 0; right: 0;
z-index: -1;
background-color: grey;
}
Mike Ross' demonstration provides a solution to your issue, but it lacks an explanation of how or why it works and could be more straightforward.
The key is to utilize the ::before notation on your element. This creates a pseudo-element that acts as the first child of the associated element, allowing you to apply additional styling. By styling the ::before selector to cover the entire screen with a specific background color:
<a class="special">Test</a>
.special:hover:before{
content: '';
position: fixed;
display: block;
top: 0; bottom: 0; left: 0; right: 0;
z-index: -1;
background-color: #ff0000;
}
You can omit nth-of-type and other unnecessary elements. Refer to my fiddle here. Just ensure that the before element covers the full screen, is positioned behind other elements, and has the desired color.
