這篇文章主要介紹了使用CSS3編寫類似iOS中的複選框及帶開關的按鈕,需要的朋友可以參考下

checkbox多選

最近寫了一個適合行動端的checkbox,如圖:

ps:中間的勾勾是iconfont,iOS風格的。

具體的HTML:

<p class="mui-checkbox-con">
    <label>
        <input class="mui-checkbox" type="checkbox">默认未选中</label>
</p>
<p class="mui-checkbox-con">
    <label>
        <input class="mui-checkbox" type="checkbox" checked>默认选中</label>
</p>
<p class="mui-checkbox-con">
    <label>
        <input class="mui-checkbox checkbox-orange" type="checkbox" checked>橘黄色 checkbox-orange</label>
</p>
<p class="mui-checkbox-con">
    <label>
        <input class="mui-checkbox checkbox-green" type="checkbox" checked>绿色 checkbox-green</label>
</p>
<p class="mui-checkbox-con">
    <label>
        <input class="mui-checkbox" type="checkbox" disabled>禁用</label>
</p>

CSS程式碼(SCSS匯出的,排版有些奇怪):

.mui-checkbox {   
  -webkit-appearance: none;   
  position: relative;   
  width: 25px;   
  height: 25px;   
  margin-right: 10px;

  background-clip: padding-box;   
  display: inline-block; }   
  .mui-checkbox:focus {

  .mui-checkbox:checked {   
    background-color: #18b4ed;   
    border: solid 1px #FFFFFF; }   
    .mui-checkbox:checked:before {   
      display: inline-block;   
      margin-top: 1px;   
      margin-left: 2px;   
      font-family: iconfont;   
      content: "\e667";   
      color: #FFFFFF;

      color: #FFFFFF;

  .mui-checkbox.checkbox-green:checked {   
    background-color: #5cb85c; }   
  .mui-checkbox.checkbox-orange:checked {   
    background-color: #f0ad4e; }   
  .mui-checkbox.checkbox-s {   
    width: 19px;   
    height: 19px; }   
    .mui-checkbox.checkbox-s:before {   
      display: inline-block;   
      margin-top: 1px;   
      margin-left: 2px;   
      font-family: iconfont;   
      content: "\e667";   
      color: #FFFFFF;   
      font-size: 13px; }   
.mui-checkbox-anim {   
  -webkit-transition: background-color ease 0.2s;   
          transition: background-color ease 0.2s; }

SCSS程式碼:

@mixin checkedCon($fs:18px) {   
  &:before {   
    display: inline-block;   
    margin-top: 1px;   
    margin-left: 2px;   
    font-family: iconfont;   
    content: "\e667";   
    color: #FFFFFF;   
    font-size: $fs;   
  }   
}   
$duration: .4s;   
.mui-checkbox {   
  -webkit-appearance: none;

  width: 25px;   
  height: 25px;   
  margin-right: 10px;   
  background-color: #FFFFFF;

    background-color: #18b4ed;   
    border: solid 1px #FFFFFF;   
    @include checkedCon();   
  }   
  &:disabled {   
    background-color: #d9d9d9;   
    border: solid 1px #d9d9d9;

    background-color: #5cb85c;   
  }   
  &.checkbox-orange:checked {   
    background-color: #f0ad4e;   
  }   
  &.checkbox-s {   
    width: 19px;   
    height: 19px;   
    @include checkedCon(13px);   
  }   
}   
.mui-checkbox-anim{   
  //border等其他元素不做过渡效果,增加视觉差,更有动画效果   
  transition: background-color ease $duration/2;   
}

#帶switch開關
本身我做這一個ui的目的是支援行動端的頁面,而webkit上也剛好支援單標記的input元素是使用偽類(:before或:after),所以我沒做更多的支援和優化,只是想盡量的保持html乾淨,所以沒用其他元素做模擬。如果你要使用在桌面應用程式上,或支援其他瀏覽器,可以自己稍微修改一下,反正我沒測試過。

今天繼續分享一個iOS風格的switch開關按鈕,樣子也非常常見,如圖:
2016411115110047.png (818×350)

主要是使用了

<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>

在實際的使用中後來又增加了兩個過渡效果,分別加mui-switch-animbg和mui-switch-anim 類別即可,具體效果查看下面的demo頁面。
