                                                            CSS3实现32种基本图形

     CSS3可以实现很多漂亮的图形,我收集了32种图形,在下面列出。直接用CSS3画出这些图形,要比贴图性能更好,体验更加,是一种非常好的网页美观方式。

     这32种图形分别为圆形,椭圆形,三角形,倒三角形,左三角形,右三角形,菱形,梯形,长方形,正方形,圆环,平行四边形,五角星,六角星,五边形,六边形,八边形,心形,蛋形,无穷符号,消息提示框,钻石,八卦图,食豆人,扇形,月牙,顶左直角三角形,顶右直角三角形 ,底左直角三角形 ,底右直角三角形 ,八角形, 十二角形。
     网页代码中用到( 

)和Div边距设置和浮动(margin: 20px 20px; float: left;)。

     参考文章:编程之家:

        1. 圆形:设置宽度和高度相等,border-radius属性为宽度或高度的一半。

     效果图:

                    

   #Circle{     width:100px;     height:100px;     float: left;     background: #6fee1d;     -moz-border-radius: 50px;     -webkit-border-radius: 50px;     border-radius: 50px;   }

    2.椭圆形:圆形的变体,高度设置为宽度的一半,border-radius属性为高度除以高度一半。

    效果图:

                 

  #Oval {     width: 200px;     height: 100px;     float: left;     background: #e9880c;     -webkit-border-radius: 100px / 50px;     -moz-border-radius: 100px / 50px;     border-radius: 100px / 50px;   }

    3.三角形:宽度和高度设置为0,border设置左,右边透明,底边可见Solid。

    效果图:

                 

  #Triangle {     width: 0;     height: 0;     float: left;     border-bottom: 100px solid #fcf706;     border-left: 50px solid transparent;     border-right: 50px solid transparent;   }

       4.倒三角形:宽度和高度设置为0,border设置左,右边透明,顶边可见Solid。

    效果图:

             

  #InvertedTriangle {     width: 0;     height: 0;     float: left;     border-top: 100px solid #30a3bf;     border-left: 50px solid transparent;     border-right: 50px solid transparent;   }

      5.左三角形:宽度和高度设置为0,border设置上,下边透明,右边可见Solid。

    效果图:

              

   #LeftTriangle {     width: 0;     height: 0;     float: left;     border-top: 50px solid transparent;     border-right: 100px solid #466f20;     border-bottom: 50px solid transparent;   }

      6.右三角形:宽度和高度设置为0,border设置上,下边透明,左边可见Solid。

      效果图:

              

  #RightTriangle {     width: 0;     height: 0;     float: left;     border-top: 50px solid transparent;     border-left: 100px solid #800820;     border-bottom: 50px solid transparent;   }

     7.菱形:使用transform和rotate相结合,使两个正反三角形上下显示。

     效果图:

           

  #Diamond {    width: 100px;    height: 100px;    float: left;    background: #8e00ff;    /* Rotate */    -webkit-transform: rotate(-45deg);    -moz-transform: rotate(-45deg);    -ms-transform: rotate(-45deg);    -o-transform: rotate(-45deg);    transform: rotate(-45deg);    /* Rotate Origin */    -webkit-transform-origin: 0 100%;    -moz-transform-origin: 0 100%;    -ms-transform-origin: 0 100%;    -o-transform-origin: 0 100%;    transform-origin: 0 100%;    margin: 40px 0 10px 240px;   }

     8.梯形:三角形的变体,设置左右两条边相等,并且给它设置一个宽度。

    效果图:

              

   #Trapezium {    height: 0;    width: 100px;    float: left;    border-bottom: 100px solid #dc2500;    border-left: 50px solid transparent;    border-right: 50px solid transparent;   }

      9.长方形:宽比高长。

     效果图:

        

   #Rectangle {    height: 50px;    width: 100px;    float: left;    background: #afe05d;   }

     10.正方形:宽和高相等。

    效果图:

            

   #Square {    height: 100px;    width: 100px;    float: left;    background: #b02089;   }

      11.圆环:在圆形的基础上设置边界,边界颜色与圆形填充颜色不同。

      效果图:

          

   #Ring {    width: 100px;    height: 100px;    float: left;    background-color: white;    border-radius: 80px;    border:5px #ffd700 solid;   }

      12.平行四边形:使用transform使长方形倾斜一个角度。

     效果图:

             

   #Parallelogram {    width: 120px;    height: 80px;    float: left;    margin-left: 10px;    -webkit-transform: skew(30deg);    -moz-transform: skew(230deg);    -o-transform: skew(30deg);    transform: skew(30deg);    background-color: #2eda01;   }

     13.五角星:星形的实现方式比较复杂,主要是使用transform属性来旋转不同的边。

      效果图:

         

  #FiveStar {     width: 0;     height: 0;     float: left;     margin: 20px 20px;     color: #ff0012;     position: relative;     display: block;     border-right: 80px solid transparent;     border-bottom: 60px solid #ff0012;     border-left: 80px solid transparent;     -moz-transform: rotate(35deg);     -webkit-transform: rotate(35deg);     -ms-transform: rotate(35deg);     -o-transform: rotate(35deg);   }   #FiveStar:before {     height: 0;     width: 0;     content: '';     position: absolute;     display: block;     top: -35px;     left: -50px;     border-bottom: 60px solid #ff0012;     border-left: 20px solid transparent;     border-right: 20px solid transparent;     -webkit-transform: rotate(-35deg);     -moz-transform: rotate(-35deg);     -ms-transform: rotate(-35deg);     -o-transform: rotate(-35deg);   }   #FiveStar:after {     width: 0;     height: 0;     content: '';     position: absolute;     display: block;     top: 3px;     left: -85px;     color: #ff0012;     border-right: 80px solid transparent;     border-bottom: 60px solid #ff0012;     border-left: 80px solid transparent;     -webkit-transform: rotate(-70deg);     -moz-transform: rotate(-70deg);     -ms-transform: rotate(-70deg);     -o-transform: rotate(-70deg);   }

      14.六角星:使用transform属性来旋转不同的边。

     效果图:

           

   #SixStar{     width: 0;     height: 0;     float: left;     border-left: 50px solid transparent;     border-right: 50px solid transparent;     border-bottom: 100px solid #cfd810;     position: relative;    }    #SixStar:after{     width: 0;     height: 0;     content: "";     border-top: 100px solid #cfd810;     border-left: 50px solid transparent;     border-right: 50px solid transparent;     position: absolute;     top: 30px;     left: -50px;    }

     15.六边形:在长方形上面和下面各放置一个三角形。

       效果图:

                

   #Hexagon {      width: 100px;      height: 55px;      float: left;      background: #000001;      position: relative;      margin: 10px auto;    }    #Hexagon:before {      content: "";      width: 0;      height: 0;      position: absolute;      top: -25px;      left: 0;      border-left: 50px solid transparent;      border-right: 50px solid transparent;      border-bottom: 25px solid #000001;   }   #Hexagon:after {     content: "";     width: 0;     height: 0;     position: absolute;     bottom: -25px;     left: 0;     border-left: 50px solid transparent;     border-right: 50px solid transparent;     border-top: 25px solid #000001;   }

     16.五边形:可以采用三角形和梯形组合。

       效果图:

    CSS3实现基本图形      
           多角形绘制比较复杂,比如五角星,八角形等。

      心形和五角星复杂,但很常用,灵活运用可以使我们的网站更加炫酷。 

      以后如果遇到其他用CSS直接绘制的图形,会收集补充到这。

Difficulty in updating caching of official account web pages: How to avoid the old cache affecting the user experience after version update?Difficulty in updating caching of official account web pages: How to avoid the old cache affecting the user experience after version update?Mar 04, 2025 pm 12:32 PM

The official account web page update cache, this thing is simple and simple, and it is complicated enough to drink a pot of it. You worked hard to update the official account article, but the user still opened the old version. Who can bear the taste? In this article, let’s take a look at the twists and turns behind this and how to solve this problem gracefully. After reading it, you can easily deal with various caching problems, allowing your users to always experience the freshest content. Let’s talk about the basics first. To put it bluntly, in order to improve access speed, the browser or server stores some static resources (such as pictures, CSS, JS) or page content.
