定义dom, 容器中包含笔头、笔杆(包含文字)和橡皮 3 部分:flex
<div class="pencil"> <span class="taper"></span> <span class="barrel">made in China</span> <span class="eraser"></span> </div>
居中显示:url
body { margin: 0; height: 100vh; display: flex; align-items: center; justify-content: center; background-color: lightskyblue; }
定义铅笔的尺寸:spa
.pencil { position: relative; width: 50em; height: 3.5em; }
画出笔杆:
.pencil .barrel { position: absolute; width: 40em; left: 4em; background-color: green; border-top: 1em solid forestgreen; border-bottom: 1em solid darkgreen; }
设置笔杆上文字的样式:
.pencil .barrel { line-height: 1.5em; font-family: sans-serif; text-transform: uppercase; color: silver; text-align: center; }
用伪元素画出笔头:
.pencil .taper::before, .pencil .taper::after { content: ''; position: absolute; left: -4em; border-style: solid; border-width: calc(3.5em / 2) 4em; } .pencil .taper::before { border-color: transparent burlywood transparent transparent; } .pencil .taper::after { border-color: transparent green transparent transparent; transform: scale(0.3); }
画出橡皮:
.pencil .eraser { position: absolute; right: 0; width: 6em; height: 1.5em; background-color: lightpink; border-top: 1em solid pink; border-bottom: 1em solid lightcoral; border-top-right-radius: 0.5em; border-bottom-right-radius: 0.5em; }
用伪元素画出橡皮上的铁箍:
.pencil .eraser::before { content: ''; position: absolute; top: -1em; left: 0; width: 1.5em; height: 1.5em; background-color: silver; border-top: 1em solid lightgray; border-bottom: 1em solid gray; }
最后,增长阴影:
.pencil { filter: drop-shadow(5px 10px 3px gray); }
大功告成!
