If your website is a WordPress website or even a regular website you may want to underline links on your website when people use the mouse to hover over the link. Just add this a:hover WordPress Code Snippet to your CSS stylesheet in your current WordPress theme in order to add an underline to links that are hovered on in WordPress.
/**
* Change link to underline on hover
*
* @author WPSnacks.com
* @link https://www.wpsnacks.com
*/
a:hover {
text-decoration: underline;
}
Your theme may likely already have the link code listed in the CSS stylesheet so you may want to search the stylesheet for that first and if it does then you can update that to the one you want.
