在HTML中,码圣如何用CSS画一棵圣诞树?请高手指教
圣诞树啊,诞树应该是网页号牌识别 源码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">
</div>
</body>
</html>
看着有点丑,圣诞树源impala源码多种语音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windows激活软件源码就成了五颜六色的网页“花”。
圣诞树
圣诞树,源码是62数据lua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。正78的源码
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。
