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>
