How to Dynamically Modify the Width of a :before Selector Using jQuery?

jQuery Manipulation of CSS :before Selectors

When faced with dynamic image widths and the need to modify :before rules accordingly, accessing these pseudoclass properties via jQuery can be a challenge. However, there is a workaround to achieve this functionality.

Solution:

To target and modify the :before selector's width property while leaving other elements unaffected, you can use the following approach:

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

This code appends a new style element to the document's head, overriding the original :before rule width with a fixed value of 800px. The !important flag ensures that the new style declaration takes precedence.

Demonstration:

See the following live demo for a practical example:

Alternatives:

While the aforementioned approach effectively changes the width property of the :before selector, there are no native jQuery methods to directly access pseudoclass rules. If you require more granular control or flexibility, consider using a specialized plugin that specifically addresses this issue.
