The first step is to draw the outline of the button
Choose the appropriate one html tag, set the outline CSS
/* html代码 */ <a href="#" class="button off"></a> body{ background-color: #E6C9B6; } /* CSS样式 */ /* 按钮轮廓 */ .button{ display: block; margin:100px auto; position: relative; width:100px; height:40px; border-radius: 50px; border:1px solid #fff; background-color: #E9E4E0; }
/* 接在上面继续写 */ .button:after{ display: block; position: absolute; //相对按钮的轮廓进行决定定位 top:2px; bottom: 2px; //即设置top,又设置bottom使元素自动拉伸到最大 left:2px; //实际上,按钮的宽度即为容器的高度-(top+bottom) width:36px; //按钮的宽度 line-height: 36px; //按钮文字的高度,如果不需要文字,可移除 text-align: center; text-transform: uppercase; font-size: 16px; background-color: #fff; //这里的背景颜色是按钮的背景颜色 border:2px solid; transition: all 500ms; //按钮的动画时长 }
.off:after { content: 'off'; border-radius:30px; color: #999; }
- 再接着绘制要切换的状态
.on:after { content: 'ON'; border-radius:30px; transform: translate(56px, 0); color:transparent; background-color:#4BD429; }

In fact, among CSS switches, toggleClass is the most convenient.
but! ! !This switching method cannot switch the JS event you want to trigger.
After all, we draw buttons to complete certain functions,
So I adopted this method, but it may not be the best
var zn=0; $('.button').click(function(e){ if(zn==1){ $(this).removeClass("on").addClass("off"); //此处可填要触发的事件 zn=0; }else{ $(this).removeClass("off").addClass("on"); //此处可填要触发的事件 zn=1; } });
绘制过程并不复杂,我也就不细说了,贴下效果图和代码,感兴趣的可以自行看一下

PS:我引用了一个初始化的CSS文件,可能需要 box-sizing:border-box; <style type="text/css"> /*开关的轮廓*/ .button{ display: block; position: relative; width:160px; height:180px; border-radius: 5px; background-color: #f1f1f1; } .button2{ display: block; position: relative; width:160px; height:180px; border-radius: 5px; background-color: #f1f1f1; } /*指示灯*/ .indicate{ display: block; position: absolute; margin:60px 0 0 70px; width: 20px; height: 4px; border-radius: 2px; background-color: #A8C1C2; z-index: 1; transition: all 200ms; } .indicate_yes{ margin:69px 0 0 70px; background-color: #A3D7E7; } /*开关内部的小按钮*/ .button:after{ display: block; position: absolute; top:40px; bottom: 40px; left:20px; right:20px; line-height: 52px; border:1px solid #FFF; transition: all 200ms; } .button2:after{ display: block; position: absolute; top:49px; bottom: 31px; left:20px; right:20px; line-height: 52px; border:1px solid #FFF; transition: all 200ms; } /*默认状态的小按钮*/ .on:after { content: ''; border-radius: 5px; /* CSS3的颜色渐变凸显按钮的凸出感 */ background: linear-gradient(#fff, #f2f2f2 80%,#fff); /* CSS3的影音的综合应用,绘制按钮的边缘,给予立体感 */ box-shadow: 0 1px 0 0 #fff, 0 3px 0.5px 0 #E7E9EA, 0 5px 0.5px 0 #DEDFDF, 0 6px 0.5px 0 #CCCCCD, 0 7px 0.5px 0 #C5C7C7, 0 8px 2px 0 #818283, 0 9px 2px 0 #A7A8A8; } /*关闭后的小按钮*/ .off:after { content: ''; border-radius: 5px; background: linear-gradient(#fff, #f2f2f2 80%,#fff); box-shadow: 0 -1px 0 0 #fff, 0 -3px 0.5px 0 #E7E9EA, 0 -5px 0.5px 0 #DEDFDF, 0 -6px 0.5px 0 #CCCCCD, 0 -7px 0.5px 0 #C5C7C7, 0 -8px 2px 0 #818283, 0 -9px 2px 0 #A7A8A8; } </style> /* JS代码 */ <script type="text/javascript"> $('.button').click(function(e) { var toggle = this; e.preventDefault(); $(toggle).toggleClass('on') .toggleClass('off') .toggleClass("button2"); //指示灯亮/灭 $(this).children(".indicate") .toggleClass("indicate_yes"); }); //localStorage.clear(); </script>
