How to Set CSS Properties in JavaScript

JavaScript enables dynamic control of web page elements, including managing their visual appearance through CSS properties. To set CSS attributes using JavaScript, the element.style property is utilized.

Example:

Suppose you have created an HTML select element using JavaScript:

var menu = document.createElement('select');

To set the width of this select element to 100 pixels, you can use the following JavaScript code:

menu.style.width = "100px";

Explanation:

The style property of an HTML element provides access to its CSS properties. By assigning a value to a specific CSS property (e.g., "width"), you can modify its value dynamically. In this case, the width of the select element will be set to 100 pixels.

Using element.style is a direct and straightforward approach to manipulating CSS attributes in JavaScript, allowing you to make real-time changes to the appearance and layout of web page elements.
