How Can JavaScript Dynamically Modify CSS Stylesheets?

Altering CSS Stylesheets Dynamically with JavaScript

Contrary to the notion that CSS stylesheets are immutable, JavaScript empowers you to modify them directly. Unlike manipulating the inline styles of individual elements, this technique targets the stylesheet itself, enabling you to alter its contents.

Achieving Stylesheet Alteration

Modern browsers provide an elegant solution for this task:

• InsertRule() Method: Dynamically adds new rules to a stylesheet.
• DeleteRule() Method: Removes existing rules from a stylesheet.
• cssRules Attribute: Accesses individual rules within a stylesheet for modification.

These methods offer a clean and efficient way to modify CSS stylesheets without resorting to workarounds.
