Absolute Positioning

Remember that for pseudo-elements to use top/left accurately, the parent must have position: relative;.

Content Property

* Note: "Before" and "After" require a 'content' property (even if empty) to render.

Frequently Asked Questions

The 'content' property is used with the ::before and ::after pseudo-elements to insert generated content into an element.

For pseudo-elements to be positioned absolutely relative to their parent, the parent must have a position other than 'static' (usually 'relative').

Yes, you can use the url() function in the content property, although text and icons are the most common uses.

Content added via pseudo-elements is generally not indexed by search engines, so use them for decorative purposes rather than essential information.
