1、用css画一个圆形
.disc1{
width: 100px
height: 100px
border:1px solid red
background-color: red
margin:300px 0px 0px 300px
border-radius:100%
float:left
}
2、由于爱心是由两个圆和一个正方形组成的,所以还需要再来一个圆形
.disc2{
width: 100px
height: 100px
border:1px solid red
background-color: red
margin:250px 0px 0px 0px
border-radius:100%
float:left
position: relative
right: 50px
}
3、心型下方就需要做一个正方形
.square{
width: 100px
height: 100px
border:1px solid red
background-color: red
margin: 300px 0px 0px 0px
float: left
position: relative
right: 152px
}
4、做完这些的效果已经基本上出来了,但是还需要调整一下爱心的角度,这时就需要用到css样式中的transform中的rotate属性了。
由于需要把三个div都旋转角度,所以把这三个div放在一个div里面。具体代码如下:
.main{
transform: rotate(45deg)
margin: 300px
}
全部代码如下
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title></title>
<style type="text/css">
*{
margin: 0px
padding: 0px
}
.main{
transform: rotate(45deg)
margin: 300px
}
.disc1{
width: 100px
height: 100px
border:1px solid red
background-color: red
margin:300px 0px 0px 300px
border-radius:100%
float:left
}
.disc2{
width: 100px
height: 100px
border:1px solid red
background-color: red
margin:250px 0px 0px 0px
border-radius:100%
float:left
position: relative
right: 50px
}
.square{
width: 100px
height: 100px
border:1px solid red
background-color: red
margin: 300px 0px 0px 0px
float: left
position: relative
right: 152px
}
</style>
</head>
<body>
<div class="main">
<div class="disc1"></div>
<div class="disc2"></div>
<div class="square"></div>
</div>
</body>
</html>
要得上面的线性渐变效果,我们这样去定义CSS3样式: background-image: -moz-linear-gradient(top, #8fa1ff, #3757fa)/* Firefox */ background-image: -webkit-gradient(linear, left top, left bottom, color-stop(0, #ff4f02), color-stop(1, #8f2c00))/* Saf4+, Chrome */ filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#c6ff00', endColorstr='#538300', GradientType='0')/* IE*/-moz-linear-gradient有三个参数。第一个参数表示线性渐变的方向,top是从上到下、left是从左到右,如果定义成left top,那就是从左上角到右下角。第二个和第三个参数分别是起点颜色和终点颜色。你还可以在它们之间插入更多的参数,表示多种颜色的渐变。线性渐变使用from()以及to()方法指定过渡颜色点: background: -webkit-gradient(linear, left top, left bottom, from(#96ff00), color-stop(0.5, orange), to(rgb(255, 0, 0)))线性渐变多个过渡点在同一位置: background:-webkit-gradient(linear, left top, left bottom, from(#00abeb), to(#fff), color-stop(0.5, #fff), color-stop(0.5, #66cc00))径向渐变综合效果演示: background: -moz-radial-gradient(30px 30px, circle farthest-corner, #58ff00 0%, rgba(222, 255, 0, 0) 30%), -moz-radial-gradient(50px 70px, circle farthest-corner, #F30 0%, rgba(255, 159, 34, 0) 60%), -moz-radial-gradient(80px 10px, circle farthest-corner, #03F 0%, rgba(222, 255, 0, 0) 80%)background:-webkit-gradient(radial, 105 105, 20, 112 120, 50, from(#ff5f98), to(rgba(255,1,136,0)), color-stop(75%, #ff0188)), -webkit-gradient(radial, 95 15, 15, 102 20, 40, from(#00c9ff), to(rgba(0,201,255,0)), color-stop(80%, #00b5e2)), -webkit-gradient(radial, 0 150, 50, 0 140, 90, from(#f4f201), to(rgba(228, 199,0,0)), color-stop(80%, #e4c700))circle farthest-corner圆形渐变,ellipse farthest-corner椭圆渐变
