前端HTML div标签的用法 盒子模型

盒子模型



边框 border …外边距 margin…

内容与边框距离padding【会撑大div边框】…

宽width…高height。

div的奇特玩法

1.把div弄成圆形

【css设置border-radius: ?px;】

例子：<div class="circle" id="c1"></div>

css：

.circle{ width: 100px; height: 100px; border-radius: 50px; background: black； }



2.div画三角形

【1.设置宽高为0，设置边框大小与颜色，要三边透明色transparent】；

例如：<div id="top" class="trdiv"></div>

css：.trdiv{ width: 0px; height: 0px; margin: 0 auto; } #top{ border-bottom: 50px green solid; border-left: 50px transparent solid; border-right: 50px transparent solid; }

3.用1，2方法画画。【门窗可用表格实现更简单】
