一些很偏门的css,用过一两次,很难记得牢,这里,我总结一些。
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 { 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 { /* 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视效果,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 { 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; 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
设置字体平滑,会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); }
