JS CSS 类 - Javascript

Javascript is one of the most popular programming languages used for developing web applications. Among the many features that make it so popular are its ability to manipulate HTML and CSS.

In this article, we will focus on the JS CSS class and how it is used to manipulate CSS with Javascript.

What is the JS CSS Class?

The JS CSS class is a Javascript function that can be used to manipulate the style of HTML elements. It works by changing the style properties of the element, such as color, width, height, and so on.

How to Use the JS CSS Class

To use the JS CSS class, you must first create a reference to the element you want to style. This can be done using the getElementById() function or the querySelector() function.

Once you have a reference to the element, you can access its style object and set its properties using the JS CSS class. For example, to change the color of a paragraph element with an ID of "paragraph", you could use the following code:

var paragraph = document.getElementById("paragraph");
paragraph.style.color = "red";

This code will change the color of the paragraph to red.

You can also use the JS CSS class to set multiple properties at once. For example, to change the color and font size of a paragraph element, you could use the following code:

var paragraph = document.getElementById("paragraph");
paragraph.style = "color: red; font-size: 16px;";

This code will change the color of the paragraph to red and set the font size to 16 pixels.

Conclusion

The JS CSS class is a powerful tool for manipulating the style of HTML elements using Javascript. By using this class, you can make your web applications more dynamic and interactive.
