jQuery is a widely used JavaScript library that provides many powerful functions and methods that can easily change HTML and CSS elements. One of the most commonly used functions is to modify, add or delete CSS properties.

In web development, CSS is an important part of controlling the style and layout of web pages. Sometimes we need to modify or delete a CSS property on the page. At this time, jQuery can come in handy.

If you want to remove a CSS attribute, just like other operations, you can use jQuery's .attr() or .css() method. The following are some practical tips that will let you know how to use jQuery to remove CSS properties in JavaScript:

Method 1: Use CSS methods to remove CSS properties

In jQuery, we can use .css () method to set or remove CSS properties. If you want to remove a CSS attribute on an element, just set the attribute value to an empty string in the .css() method.

For example, we have the following style code in an HTML file:

This is a heading

Copy after login

If we want to remove its color attribute, we can use the following method:

$('h1').css('color', '');
Copy after login

This way The color attribute of the h1 element can be successfully removed.

Method 2: Use the removeAttr() method to remove CSS attributes

In addition to using the .css() method, jQuery also provides a practical method: removeAttr(). This method removes the specified attribute from the specified element.

For example, in the above HTML code, we can also use the removeAttr() method to remove the color attribute of the h1 element:

$('h1').removeAttr('style');
Copy after login

This code will move all style attributes on the h1 element remove. If you want to remove only one of the attributes, you can specify the name of the attribute to be removed in the removeAttr() method.

Method 3: Use the removeClass() method to remove the CSS class

In addition to individual attributes, we can also remove the CSS class of the element. As shown below:

Copy after login

To remove the exampleClass class on this div element, we can use the removeClass() method:

$('div').removeClass('exampleClass');
Copy after login

In this way, the exampleClass class on this div element can be successfully removed.

Summary:

The above are three practical tips that can help us remove CSS attributes. Using jQuery you can easily manipulate HTML and CSS, making web development more convenient and efficient.
