How Can I Retrieve Specific CSS Values Using JavaScript?

Retrieve CSS Values with JavaScript Functionality

In web development, accessing CSS properties via JavaScript can be valuable. While setting values is familiar, obtaining current CSS styles is also essential. This article delves into the JavaScript method for retrieving specific CSS values efficiently.

Retrieving CSS Properties

Despite the ability to extract the entire CSS style string for an element, it's often unnecessary. The getComputedStyle() method in JavaScript provides a cleaner approach for accessing precise CSS values.

Implementation

To demonstrate, let's retrieve the "top" style property for an element with the ID "image_1":

var element = document.getElementById('image_1'),
    style = window.getComputedStyle(element),
    top = style.getPropertyValue('top');
console.log(top);

This code snippet will extract the current "top" style, log it to the console, and display its value.

Conclusion

Utilizing the getComputedStyle() method enables developers to easily retrieve individual CSS property values in JavaScript. This technique enhances code efficiency and simplifies the process of manipulating CSS styles dynamically.
