今天千锋扣丁学堂HTML5培训老师给大家分享一篇关于CSS美化单选框radio、多选框checkbox和switch开关按钮的详细介绍,下面我们一起来看一下吧。<!-- input的id必须有,这个是label进行元素匹配所必需的 --> <!-- 可以看到每个input的id和label的“for”属性对应同一字符串 --> <input type="checkbox" id="checkbox01" /> <label for="checkbox01"></label> <input type="checkbox" id="checkbox02" /> <label for="checkbox02"></label> <input type="checkbox" id="checkbox03" /> <label for="checkbox03"></label> <input type="checkbox" id="checkbox04" /> <label for="checkbox04"></label>
/* 隐藏所有checkbox */ input[type='checkbox'] { display: none; } /* 对label进行模拟.背景图片随便拼凑的,不要吐槽品味*/ /* transition效果是做个背景切换效果,这里单纯演示而已,实际上这个过渡不加更自然*/ label { display: inline-block; width: 60px; height: 60px; position: relative; background: url(//www.chitanda.me/images/blank.png); background-position: 0 0px; -webkit-transition: background 0.5s linear; } /* 利用相邻选择符和checkbox`:checked`的状态伪类来模拟默认选中效果(就是点击后那个勾号的效果) */ /*如果这段代码注释,点击后将没有任何反馈给用户*/ /*因为label本身是没有点击后被选中的状态的,checkbox被隐藏后,这个状态只能手动模拟*/ input[type='checkbox']:checked+label { background-position: 0 -60px; }
/* 伪元素的生效很简单,定义`content`就好,其余的属性和普通div一样 */ label::after { content: attr(data-name); /*利用attr可以减少css代码量,data-name写在html部分的label属性里*/ display: inline-block; position: relative; width: 120px; height: 60px; left: 100%; vertical-align: middle; margin: 10px; }
<input type="radio" id="radio"> <label for="radio"></label>
input{ display:none; } label { display: inline-block; width: 30px; height: 30px; border: 1px solid #333; border-radius: 50%; position: relative; } label::after { -webkit-transition: all .5s ease; -moz-transition: all .5s ease; -o-transition: all .5s ease; -ms-transition: all .5s ease; transition: all .5s ease; cursor: pointer; position: absolute; width: 16px; height: 16px; border-radius: 50%; top: 50%; left: 50%; margin-top:-8px; margin-left:-8px; z-index: 1; content: ''; border:1px solid #333; } input:checked+label::after{ background:red; }
实现效果点击前和点击后:
<input type="checkbox" id="checkbox"> <label for="checkbox"></label>
input{ display:none; } label { display: inline-block; width: 30px; height: 30px; border: 1px solid #333; position: relative; } label::after { -webkit-transition: opacity .5s ease; -moz-transition: opacity .5s ease; -o-transition: opacity .5s ease; -ms-transition: opacity .5s ease; transition: opacity .5s ease; cursor: pointer; position: absolute; content: ''; opacity: 0; } input:checked+label::after{ border: 2px solid #d73d32; border-top: none; border-right: none; -webkit-transform: rotate(-45deg); -ms-transform: rotate(-45deg); transform: rotate(-45deg); width:20px; height:10px; top:50%; margin-top:-8px; left:50%; margin-left:-10px; opacity: 1.0; }
<label><input class="mui-switch" type="checkbox"> 默认未选中</label> <label><input class="mui-switch" type="checkbox" checked> 默认选中</label> <label><input class="mui-switch mui-switch-animbg" type="checkbox"> 默认未选中,简单的背景过渡效果,加mui-switch-animbg类即可</label> <label><input class="mui-switch mui-switch-animbg" type="checkbox" checked> 默认选中</label> <label><input class="mui-switch mui-switch-anim" type="checkbox"> 默认未选中,过渡效果,加 mui-switch-anim 类即可</label> <label><input class="mui-switch mui-switch-anim" type="checkbox" checked> 默认选中</label>
css代码:
