代码<div id="box"> <div class="option">民主</div> <div class="option">文明</div> <div class="option">和谐</div> <div class="option">自由</div> <div id="start">Start</div&gt

效果话不多说 代码如下<div class="container"> <civ class="circle"></civ> <span>COOL</span></div>样式 .container { position: relative; width: 100%; height: 100vh; border: 1px solid red;

代码如下角度可调整其他几条border宽度来实现角度变化div{ width: 0px; height: 0px; border-top: 10px solid rgba(0, 0, 0, 0); border-right: 10px solid rgba(0, 0, 0, 0); border-bottom: 10px solid red; border-left: 10px solid rgba(0, 0, 0, 0);
