What is the purpose of using pseudo-elements before and after in HTML?

Can you set a style for pseudo-elements within an HTML container? Like so:

<div style=":after{background:blue}">

I have to define the background image dynamically, so I want to include the style in the HTML.

Answer №1

Unfortunately, it is not possible to use selectors in the style attribute.

Here are some resources to learn more:

CSS Pseudo-classes with inline styles

http://www.w3.org/TR/css-style-attr/ (W3C Recommendation)

Alternatively, you can utilize the <style>...</style> tag to add CSS directly in your HTML file.

Answer №2

Consider using jQuery to dynamically inject content after creating the background.

CSS is where you should specify pseudo-elements.
