在HTML中,码圣如何用CSS画一棵圣诞树?请高手指教
圣诞树啊,诞树应该是网页高效源码阅读分析考虑怎样画三角形吧,用border就可以了哈。源码<!DOCTYPE html><html>
<head>
<title></title>
<style type="text/css">
.ss{
height: 0;
width: 0;
position: absolute;
border: px solid tan;
border-color: transparent transparent #1fd transparent;
}
.s1{
border-width:px ;
top: px;
left: px;
}
.s2{
border-width:px ;
top: px;
left: px;
}
.s3{
border-width:px ;
top: px;
left: px;
}
.s4{
border-width:px ;
top: px;
left: px;
}
.dd{
height: px;
width: px;
position: absolute;
top: px;
left: px;
background-color: #1fd;
}
</style>
</head>
<body>
<div class="s1 ss"></div>
<div class="s2 ss"></div>
<div class="s3 ss"></div>
<div class="s4 ss"></div>
<div class="dd">

看着有点丑,圣诞树源码支付打包源码楼主可以改变宽度高度以及颜色哈。码圣最后希望采纳哈
七彩圣诞树原理
七彩圣诞树原理
七彩圣诞树原理是诞树:结晶原理。让圣诞树开花的网页液体叫做磷酸二氢钾。当纸张浸入此溶液后,源码溶液借助毛细作用在纸树中扩散,圣诞树源随着水分蒸发就会出现结晶现象。码圣而且颜色会被晶体吸收后,诞树电玩城源码程序就成了五颜六色的网页“花”。
圣诞树
圣诞树,源码是电话营销系统源码指用灯烛和装饰品把枞树或洋松装点起来的常青树。年月,大阪USJ推出冬季圣诞树,连续9年刷新吉尼斯世界纪录。股票买点 公式源码
作为是圣诞节重要的组成元素之一,近代圣诞树起源于德国,后来逐步在世界范围内流行起来,成为圣诞节庆祝中最有名的传统之一。
据说圣诞树最早出现在古罗马月中旬的农神节。现在通常人们在圣诞前后把一棵常绿植物如松树弄到屋里或户外,并用圣诞灯和彩色的装饰物装饰。
