How to remove css in jquery

In modern web design, CSS is a very important element. It is not only used for the design of page layout and style, but also a necessary case to achieve many interactive effects. As a popular JavaScript library, jQuery is also widely used in web development.

In some cases, we may need to use jQuery to dynamically modify the CSS styles on the page, such as changing the background color of elements, font size, etc. In some cases, we need to remove a specific CSS style. So, how to remove CSS styles with jQuery? Several methods will be introduced below.

Method 1:

The first method is to use jQuery’s removeProp() function. This method is a function provided after jQuery 1.7 version, which can completely remove the given attribute from the element.

For example, we need to remove the background color from a div. The following code can be used:

$(‘div’).removeProp(‘background-color’);

This function will completely remove the given attribute from the element instead of simply setting its value to the default value.

However, this method only works with the latest version of jQuery. If you're using an earlier version, you'll need to consider other methods.

Method 2:

The second method is to use jQuery’s css() function. For this function, we can pass a value called null to remove a CSS property. For example:

$(‘div’).css(‘background-color’,null);

This function will remove the background color CSS property from the element. Actually, null value can be used with any CSS property as it will remove the value of the specified property.

This method works in most versions of jQuery. However, we can also find other ways to achieve the same effect.

Method 3:

The third method is to use the removeAttr() function in jQuery. Similar to the first method, this function can directly remove the specified attributes from the element. The sample code is as follows:

$(‘div’).removeAttr(‘background-color’);

This method can be used in any version of jQuery. However, please note that this method can remove any property, not just CSS properties.

Through the above three methods, we can remove any specific CSS properties in jQuery. No matter which method you use, removing CSS styles is easy as long as you know the names of the properties you need to remove.
