Unlock the Power of CSS :hover
What is CSS :hover?
The :hover pseudo-class selector is a game-changer for web developers. It allows you to apply styles to an element when the mouse is moved over it, creating a dynamic and engaging user experience.
Putting it into Practice
Let’s dive into an example implementation. We can apply the :hover pseudo-selector to all <a> elements, making the text color change to a vibrant orange-red when the mouse hovers over the element.
a:hover {
color: #FF9900;
}See it in action on CodePen.
Taking it to the Next Level
But that’s not all! We can also apply the :hover selector to all elements within the <body> element, creating a yellow background when the mouse moves over them. Want to get really creative? You can change the border, border-radius, font, text color, padding, margin, and more!
body *:hover {
background-color: #FFFF00;
}Universal Application
To apply the :hover selector to all elements in the document, simply use the asterisk (*). This will cause the borders of hovered elements to be 1px wide, solidly red-orange in color.
*:hover {
border: 1px solid #FF9900;

- Monitor and track key frontend performance metrics
- Replay user sessions with application state
- Log network requests
- Automatically surface all errors
By following these guidelines, you can ensure a seamless and efficient user experience.
