html 复制代码

<!DOCTYPE html>
<html>
	<head>
		<meta charset="utf-8">
		<title></title>
		<style>
			*{
				margin: 0;
				padding: 0;
			}
			ul,li{
				list-style-type: none;
			}
			input{
				width: 300px;
				height: 25px;
				font-size: 14px;
				line-height: 25px;
				border: 1px solid #339999;
				color: #ff0000;
				background-color: #99CC66;
			}
			textarea{
				width: 400px;
				height: 300px;
				line-height: 24px;
				border:  none;  //清除前面的边框影响
				border: 1px solid #ff7300;
				background: #99CC99;
				display: block;
			}
		</style>
	</head>
	<body>
		<form action="#">
			<ul>
				<li><label for="user">文本框：</label>
					<input type="text" value="颜色" name="user" id="user" />
				</li>
				<li><label for="text">文本区域：</label>
					<textarea name="text" id="text" cols="30" rows="10">背景</textarea>
				</li>
			</ul>


		</form>
	</body>
</html>
