    被遗忘的CSS

    来源:segmentfault 发布时间:2018-04-07 阅读次数:

      平时在工作中遇到一些比较偏门的 css ,用过一两次,但是老是记不住,于是?#20013;?#35201;去 baidu、 google ,所以都积累起来,方便以后查看


    outline 当input选中的时候会出现一个边框

    /*一般设置成 none*/
    textarea:focus, input:focus{
        outline: none;
    }

    contenteditable 规定元素内容是否可编辑

    <div id="example-one" contenteditable="true">
    #example-one { 
        margin-bottom: 10px; 
    }
    [contenteditable="true"] { 
        padding: 10px; outline: 2px dashed #CCC; 
    }
    [contenteditable="true"]:hover { 
        outline: 2px dashed #0090D2; 
    }

    webkit-playsinline video 都可以在页面中播放,而不是全屏播放

    <video id="myvideo" src="test.mp4" webkit-playsinline="true"></video>

    clearfix 清除浮动

    .clearfix {
        zoom: 1;
    }
    .clearfix:after {
         visibility: hidden;
         display: block;
         font-size: 0;
         content: " ";
         clear: both;
         height: 0;
     }

    user-select 禁止选中文本

    p {
        -webkit-user-select: none; /* Chrome, Opera, Safari */
        -moz-user-select: none; /* Firefox 2+ */
        -ms-user-select: none; /* IE 10+ */
        user-select: none; /* Standard syntax */
    }

    webkit-scrollbar 自定义浏览器滚动条

    /*定义滚动条宽高及背景,宽高分别对应横竖滚动条的尺寸*/
    
    div::-webkit-scrollbar {
        width: 5px;
        height: 5px;
        background-color: rgba(245, 245, 245, 0.47);
    }
    
    /*定义滚动条的轨道,内阴影及圆角*/
    
    div::-webkit-scrollbar-track {
        -webkit-box-shadow: inset 0 0 6px rgba(0, 0, 0, .3);
        border-radius: 10px;
        background-color: #f5f5f5;
    }
    
    /*定义滑块,内阴影及圆角*/
    
    div::-webkit-scrollbar-thumb {
        /*width: 10px;*/
        height: 20px;
        border-radius: 10px;
        -webkit-box-shadow: inset 0 0 6px rgba(0, 0, 0, .3);
        background-color: rgba(85, 85, 85, 0.25);
    }

    webkit-appearance 去除默认样式

    input, button, textarea, select {
        *font-size: 100%;
        -webkit-appearance:none;
    }

    使用CSS transforms 或者 animations时可能会有页面闪烁的bug

    elements {
         -webkit-backface-visibility: hidden; 
    }

    transform-style: preserve-3d 让元素支持3D

    elements {
        -webkit-transform: rotateY(60deg); /* Chrome, Safari, Opera */
        -webkit-transform-style: preserve-3d; /* Chrome, Safari, Opera */
        transform: rotateY(60deg);
        transform-style: preserve-3d;
    }

    perspective 这个属性定义子元素会获得透?#26377;?#26524;,而不是元素本身

    <div class="cube pers250">
        <div class="face front">1</div>
        <div class="face back">2</div>
        <div class="face right">3</div>
        <div class="face left">4</div>
        <div class="face top">5</div>
        <div class="face bottom">6</div>
    </div>
    .cube {
      width: 100%;
      height: 100%;
      backface-visibility: visible;
      perspective-origin: 150% 150%;
      transform-style: preserve-3d;
      -webkit-backface-visibility: visible;
      -webkit-perspective-origin: 150% 150%;
      -webkit-transform-style: preserve-3d;
    }
    .pers250 {
      perspective: 250px;
      -webkit-perspective: 250px;
    }
    .face {
      display: block;
      position: absolute;
      width: 100px;
      height: 100px;
       border: none;
      line-height: 100px;
      font-family: sans-serif;
      font-size: 60px;
      color: white;
      text-align: center;
    }

    css实现不换行、自动换行、强制换行

    /*不换行*/
    white-space:nowrap;
    
    /*自动换行*/
    word-wrap: break-word; 
    word-break: normal; 
    
    /*强制换行*/
    word-break:break-all;

    font-smoothing 设置字体?#20132;?#20250;让字体看起来比较舒服

    h1, .h1, h2, .h2, h3, .h3, h4, .h4, h5, .h5, h6, .h6, p, .navbar, .brand, a, .td-name, td {
        -moz-osx-font-smoothing: grayscale;
        -webkit-font-smoothing: antialiased;
        font-family: "Microsoft YaHei", "微软雅黑", 'Muli', "Helvetica", Arial, sans-serif;
    }

    ::selection 修改选中文本颜色

    ::selection {
        color: white;
        background-color: rgba(0, 0, 0, 0.8);
    }
    ::-webkit-selection {
        color: white;
        background-color: rgba(0, 0, 0, 0.8);
    }
    ::-moz-selection {
        color: white;
        background-color: rgba(0, 0, 0, 0.8);
    }
