Read and write css attributes of HTML elements
jQuery’s css() method is used to set or read the css attributes of HTML elements.
The CSS syntax for reading elements is as follows:
css("propertyname");
For example, the following code gets the background color of the first
element.
[javascript]
$("p").css("background-color");
$("p").css("background-color");
Use the following Syntax to set CSS properties of HTML elements:
css("propertyname", "value");
For example, the following code sets the background color to yellow for all
elements.
[html]
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>JQuery Demo</title>
<script src="scripts/jquery-1.9.1.js"></script>
<script>
$(document).ready(function () {
$("button").click(function () {
$("p").css("background-color", "yellow");
});
});
</script>
</head>
<body>
<h2 id="This-nbsp-is-nbsp-a-nbsp-heading">This is a heading</h2>
<p style="background-color: #ff0000">This is a paragraph.</p>
<p style="background-color: #00ff00">This is a paragraph.</p>
<p style="background-color: #0000ff">This is a paragraph.</p>
<p>This is a paragraph.</p>
<button>Set background-color of p</button>
</body>
</html>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>JQuery Demo</title>
<script src="scripts/jquery-1.9.1.js"></script>
<script>
$(document).ready(function () {
$("button").click(function () {
$("p").css("background-color", "yellow");
});
});
</script>
</head>
<body>
<h2 id="This-nbsp-is-nbsp-a-nbsp-heading">This is a heading</h2>
<p style="background-color: #ff0000">This is a paragraph.</p>
<p style="background-color: #00ff00">This is a paragraph.</p>
<p style="background-color: #0000ff">This is a paragraph.</p>
<p>This is a paragraph.</p>www.2cto.com
<button>Set background-color of p</button>
</body>
</html>
css() also supports multiple CSS properties at the same time: its syntax is as follows:
css({"propertyname":"value","propertyname":"value",…});
For example:
[javascript] view plaincopyprint?
$("p").css({"background-color":"yellow","font-size":"200%"});
$(" p").css({"background-color":"yellow","font-size":"200%"});
