css如何绘制特殊图形的方法示例

建站知识 2021-07-03 07:55www.168986.cn长沙网站建设

一、三角形

border边框设置

代码

width: 300px;
height: 300px;
background: red;
border: 40px solid black;
border-left-color: blue;
border-bottom-color: yellow;
border-right-color: pink;
border--color: #008800;

花特殊图形的时候需要将宽高设置成0

效果

代码

width: 0;
height: 0;
background: transparent;
border: 40px solid black;
border-left-color: blue;
border-bottom-color: yellow;
border-right-color: pink;
border--color: #008800;

1、等腰三角形将其他的边的border设置成透明

代码

width:0;
height: 0;
background: transparent;
border: 40px solid black;
border-left-color: transparent;
border-bottom-color: yellow;
border-right-color: transparent;
border--color: transparent;

2、直角三角形

代码先写出个完整的div,再使用border--width0；来截取三角形

border--width/border-bottom-width:0=》就是在中间横着劈开一道，保留上边或者下边

border-left-width/border-right-width:0=》就是在中间竖着劈开一道，保留左边或者右边

.rightAngle{
    width: 0;
    height: 0;
    background: transparent;
    border: 40px solid black;
    border-left-color: blue;
    border-bottom-color: yellow;
    border-right-color: pink;
    border--color: #008800;
    border--width: 0;
    border-left-width: 0;
    border-right-color: transparent;
}

3、梯形

彩带图形

代码

width: 300px;
height: 0;
background: transparent;
border: 40px solid #008800;
border-left-color: transparent;
border-bottom-color: yellow;
border-right-color: transparent;
border--color: #008800;

梯形

代码将上面彩带图形的宽度减少，然后将上面的梯形设置为透明

width: 100px;
height: 0;
background: transparent;
border: 40px solid #008800;
border-left-color: transparent;
border-bottom-color: #008800;
border-right-color: transparent;
border--color: transparent;

通过设置长度和高度，以及设置border的透明度来拼凑成想要的图形 4、圆形

4、图形

代码 使用border-radius:50%;

.circle{
    width: 100px;
    height: 100px;
    border: 0;
    border-radius: 50%;
    background-color: orange;
}

5、椭圆

图形

代码

.ellipse{
    width: 200px;
    height: 120px;
    background-color: orange;
    border--left-radius: 50%;
    border--right-radius: 50%;
    border-bottom-left-radius: 50%;
    border-bottom-right-radius: 50%;
}

一个displayblock的元素设定宽高之后表现为矩形。通过设定border-radius可以得到圆角矩形，圆形和椭圆形。

在使用border-radius时，有几点可能需要注意一下

  • border-radius，可以分别对4个角进行设定。 例如上图border--left-radius: apx bpx;
  • border-xxx-xxx-radius的两个值分别代表着椭圆长轴和短轴长度的一半，通常简写的时候例如border--left-radius: 10px;(border--left-radius:10px 10px;) 表明长轴和短轴的长度均为20px，也就是半径为10px的圆形（圆角部分）。
  • 当使用百分比数值时，a 相对于width， b相对于height 6、特殊图形

（1）斜边三角形

图形

代码先画个等边三角形，然后再转换角度

.beveledTriangle{
    margin: 50px;
    width: 0;
    height: 0;
    border: 20px solid #2b81af;
    border--width: 40px;
    border--color:transparent;
    border-bottom-width: 40px;
    border-bottom-color: transparent;
    border-left-width: 0;
    border-right-color: #008800;
    border-right-width: 25px;
    transform-origin:center center;
    transform:rotateY(-180deg) rotate(-44deg)  ;
}

（2）绘制一条“小尾巴”

图形

代码

.tail{
    margin: 50px;
    width: 100px;
    height: 70px;
    border--right-radius: 70px 70px;
    border-right:6px solid #000000;
}

当对一个角应用圆角样式， 如果这个角相邻的两个boeder一个有定义而一个无定义 ，那么绘制的结果就是有粗到细的“小尾巴了”

7、绘制QQ图案（取自AlloyTeam案例）

图形

代码
