JQuery basic code for changing CSS styles

Either of them accepts two input parameters: style attributes and style values, separated by commas. For example, to change the link color, we can use the following code: Copy codeThe Code is as follows: $ ("# 61dh a" ).css ('color', '#123456 ');
// Here, the selector '$ ("# 61dh a")' indicates all links under the element whose ID is '# 61dh.
//. Css ('color', '#123456'); sets the color to '#123456'

If we need to change multiple style attributes, We can first define the attribute variables and then assign them to the css () method. Example:Copy codeThe Code is as follows: var divcss = {
Background: '# EEE ',
Width: '478px ',
Margin: '10px 0 0 ',
Padding: '5px 10px ',
Border: '1px solid # CCC'
};
$ ("# Result" cmd.css (divcss );
// Here we first define a CSS style attribute variable 'divcss ', which is similar to creating an external CSS file.
// Then, use the css () method provided by jQuery to assign the property to the DIV with ID '# result.

In addition, the css () method provided by jQuery can also be used to view the css attribute values of an element. For example, to view the link color, use the following code:Copy codeThe Code is as follows: $ ("# 61dh a" ).css ("color ")
// Similar to the first example, but here we only pass one parameter (style attribute)

Finally, we will introduce how to set the link style (for example, color) after the mouse is crossed ). We cannot use the selector to directly select the link in the mouse over the status, that is, $ ("a: hover") is not valid. Therefore, we need to use the event class method-hover () provided by jQuery (). It is worth noting that the hover () method needs to define two functions, one is mouse stroke, and the other is behind the mouse. The specific method is as follows:Copy codeThe Code is as follows: $ ("# 61dh a" ).css ('color', '#123456 ');
$ ("# 61dh a"). hover (function (){
Watermark (this).css ('color', '#999 ');
},
Function (){
Watermark (this).css ('color', '#123456 ');
});
// Use commas to separate the two functions of the hover () method.

You may have noticed that this method is not concise at all (against jQuery's purpose ),
In fact, the hover () method provided by jQuery is not used to change the CSS style. In practical use, we recommend that you use the Add/remove CSS method to change the style of the link over the mouse.
