用csss做三角形使用border属性
一.
<head lang="en">
<meta charset="UTF-8">
<title></title>
<style>
.div1{
border: 200px solid red;
border-color: transparent transparent black transparent;
width: 0;
}
</style>
</head>
<body>
<div class="div1"></div>
</body>
或者是
<head lang="en">
<meta charset="UTF-8">
<title></title>
<style>
.div1{
border-top: 10px solid gray;
border-right: 10px solid transparent;
border-bottom: 10px solid transparent;
border-left: 10px solid transparent;
width: 0;
}
</style>
</head>
<body>
<div class="div1"></div>
</body>
二.用border-radius做椭圆.圆角效果.圆
或者用几个div也可以做圆角效果用css2.0做很麻烦这里也只是提一下
三.用background-image:radial-gradient(circle at 50% 0%,#fff,71%,transparent 71%);可以实现波浪效果;
