How to Dynamically Alter the Width of a :before Pseudo-Element using jQuery?

Altering :before CSS Selectors Width using JQuery

In order to dynamically set the width of the :before pseudo-element, you can append a new style element to the document's head.

JQuery Code:

$('head').append('<style>.column:before{width:800px !important;}</style>');

Explanation:

• $('head') selects the element of the HTML document.
• .append() method adds the new style element to the element.
• Inside the style element, we set the width property of the .column:before selector to 800 pixels, overriding the original width.

Note:

• The !important declaration is used to ensure that the new width overrides any previously set styles.
• It's worth noting that there are no direct jQuery methods to modify the rules of a pseudo-class. The provided solution involves modifying the CSS stylesheet.

This technique allows you to dynamically change the width of elements with the :before pseudo-element, while leaving elements without it unaffected.
