Default style of drop-down list:

##Introduced below Two methods to customize the drop-down list:

Method 1:

Use pure CSS to customize the style of the drop-down list.

Principle: Clear the default drop-down list style, customize the style, and attach a small arrow picture aligned to the right.

<!doctype html>
<html>
	<head>
		<style type="text/css">
			select{
				width:200px;
				height:30px;
				appearance:none;
			    -moz-appearance:none;
			    -webkit-appearance:none;
				background: url("images/select.png") no-repeat right center;
				font-size:16px;
				font-family:Microsoft YaHei;
				color:red;
			}
		</style>
	</head>
	<body>
		<form action="" method="post">
			<select>
				<option value="请选择">请选择</option>
				<option value="北京">北京</option>
				<option value="上海">上海</option>
				<option value="广州">广州</option>
			</select>
		</form>
	</body>
</html>

Problem: Modifying the width and height of option is invalid.

Method 2:

Use p+ul+jQuery to implement custom style drop-down list selection.

##HTML code:

<p id="container">
	<form action="" method="post">
		<p>
			<ul>
				<li class="active">请选择</li>
				<li>北京</li>
				<li>上海</li>
				<li>广州</li>
			</ul>
		</p>
	</form>
