In the ever-evolving world of web development, understanding how to access and manipulate browser styles is a crucial skill. The Browser Object Model (BOM) provides a powerful set of tools that allow you to dynamically change the appearance and behavior of your web pages.

In this article, we’ll explore the BOM and dive into practical examples that will help you take your web development skills to the next level.

Accessing Browser Styles with JavaScript

The BOM offers a direct way to access and modify the styles of your web page elements. The window.getComputedStyle() method allows you to retrieve the computed styles of an element, including those applied by CSS. Here's an example:

// Get the element you want to style
const myElement = document.getElementById('my-element');

// Get the computed styles of the element
const styles = window.getComputedStyle(myElement);

// Access a specific style property
const backgroundColor = styles.getPropertyValue('background-color');
console.log(backgroundColor); // Output: 'rgb(255, 255, 255)'
