这次分享的电扇,和以往用css3画人物相比 多加了一点交互,就是电扇开关的地方,用到了一点点css3的 :checked +div 这个很少用到的选择器来实现的。

效果是这样的
HTML 结构
小技巧就是,一开始就写了一组单选按钮来做开关的部分。把单选按钮的透明度设为0,然后在后面叠加一个div来画开关的样式。
<div id="fan"> <input type="radio" name="switch" class="switch_0"/> <div class="switch_btn_0">0</div> <input type="radio" checked name="switch" class="switch_1"/> <div class="switch_btn_1">1</div> <input type="radio" name="switch" class="switch_2"/> <div class="switch_btn_2">2</div> <input type="radio" name="switch" class="switch_3"/> <div class="switch_btn_3">3</div> <div class="mask"> <div class="logo">CSS3 Fan</div> <div class="line_1"></div> <div class="line_2"></div> <div class="line_3"></div> <div class="line_4"></div> <div class="line_5"></div> <div class="line_6"></div> <div class="leafs"> <div class="leaf_1"></div> <div class="leaf_2"></div> <div class="leaf_3"></div> </div> </div> <div class="header"></div> <div class="neck"></div> <div class="neck_footer"></div> <div class="bottom"></div> <div class="bottom_footer_1"></div> <div class="bottom_footer_2"></div> </div>
开关部分的LESS代码如下
.switch{ position: absolute; width: 24px; height: 24px; top: 296px; z-index: 13; opacity: 0; cursor: pointer; } .switch_0{ .switch; left: 50px; &:checked+div{ &+input+div+input+div+input+div+.mask{ .leafs{ animation-play-state:paused; } } } } .switch_1{ .switch; left: 75px; &:checked+div{ background: #a9af27; color: #0e6873; &+input+div+input+div+.mask{ .leafs{ animation-duration : 0.7s } } } } .switch_2{ .switch; left: 100px; &:checked+div{ background: #a9af27; color: #0e6873; &+input+div+.mask{ .leafs{ animation-duration : 0.4s } } } } .switch_3{ .switch; left: 125px; &:checked+div{ background: #a9af27; color: #0e6873; &+.mask{ .leafs{ animation-duration : 0.3s } } } }
看起来有点low。
至于电扇的CSS样式部分就不再赘述了。
有个地方需要优化,就是在换挡的时候,动画应该柔和些。有同学想到用什么办法优化下吗?
