JQuery css () method to change existing CSS styles _jquery

Getting Started with jquery: Using the CSS () method to change an existing CSS style sheet, the CSS () method has a variety of uses. One of these can accept two input parameters: style properties and style values, separated by commas. For example, to change the link color, you can write code like this:

$ ("#61dh a"). css (' color ', ' #123456 '); 
Selector ' $ (' #61dh a ') ' represents all links under the element with Id ' #61dh '. 
//.css (' Color ', ' #123456 ') means to set the color to ' #123456 '

If you need to change multiple style properties, you can first define the property variable and then assign it directly to the CSS () method.

var mycss = { 
background: ' #EEE ', 
width: ' 478px ', 
margin: ' 10px 0 0 ', 
padding: ' 5px 10px ', 
border: ' 1 PX solid #CCC ' 
}; 
$ ("#result"). CSS (DIVCSS);

The code above defines a CSS style property variable "Mycss", similar to creating an external CSS file, and then using the CSS () method to assign the attribute to the DIV with id ' #result '.

Additionally, the CSS () method provided by jquery can also view the CSS property values of an element. For example, to see the color of the link, the code is as follows:

$ ("#61dh a"). CSS ("color")

You will find that this is similar to the first example, but only one argument (style attribute) is passed here.

The last thing to introduce is how to set the link style after the mouse stroke (for example: color), you need to use the JQuery event class Method-hover (). It is worth noting that the hover () method needs to define two functions, one is the mouse is out of date, and the other is after the mouse is drawn. The specific methods are as follows:

$ ("#61dh a"). css (' color ', ' #123456 '); 
$ ("#61dh a"). Hover (function () { 
$ (this). CSS (' color ', ' #999 '); 
}, 
function () { 
$ (this). CSS (' Color ', ' #123456 '); 
The two functions of the hover () method are separated by commas

Perhaps smart you have noticed that this method is not concise, oh, in fact, the jquery hover () method is not used to change the CSS style. In practical use, it is recommended to use the Add/Remove CSS method to change the mouse across the link style.
