How to set css height in jquery

jQuery is a very popular JavaScript library that can make our web development process simpler and more efficient. Among them, setting CSS height is one of the frequently used functions. Next, this article will introduce how to set CSS height using jQuery.

In jQuery, we can use the height() method to set the height of an element. For example:

$(selector).height(value);

Among them, selector is the element whose height is to be set, and value is the height value to be set. Here are some usage examples:

1. Set the fixed height of the element

$("p").height("100px");

The above code can set the height of all p elements in the page to 100 pixels.

2. Adaptive height according to content

$("p").height("auto");

The above code can adaptively set its height according to the content in the p element.

3. Set the same height as other elements

$("p").height($("#other").height());

The above code can set the height of the p element to be the same as the height of the element with id other.

2. Use the css() method to set the CSS height

In addition to using the height() method, we can also use the css() method to set the CSS attributes of the element, including the height attribute. For example:

$(selector).css("height", value);
