所有一切都垂直居中,在IE11中要小心FLEXBOX
html,body{ height:100%; margin:0; } body{ -webkit-align-items:center; -ms-flex-align:center; align-items:center; display:-webkit-flex; display:flex; }文字投影
text-shadow:1px 1px 0px #630阴影效果
-webkit-box-shadow: 0 1px 1px rgba(0,0,0,.2); -moz-box-shadow: 0 1px 1px rgba(0,0,0,.2); box-shadow: 0 1px 1px rgba(0,0,0,.2);网站变成灰色
html { filter: grayscale(100%);//IE浏览器 -webkit-filter: grayscale(100%);//谷歌浏览器 -moz-filter: grayscale(100%);//火狐 -ms-filter: grayscale(100%); -o-filter: grayscale(100%); filter:progid:DXImageTransform.Microsoft.BasicImage(grayscale=1); -webkit-filter: grayscale(1);//谷歌浏览器 }div禁止选择
unselectable="on" onselectstart="return false;"CSS 中form表单两端对齐,做form表单的时候,前面经常有姓名,年龄,公司名称等等,有的是2个字,有的是4个字,如何让字对齐呢?有的人的做法是打几个空格,但是这样不是很准确,最好的办法是如下:
<div class="box1"> <div class="test1">姓 名</div> <div class="test1">姓 名 姓 名</div> <div class="test1">姓 名 名</div> <div class="test1">所 在 地</div> <div class="test1">工 作 单 位</div> </div>
.test1 { text-align:justify; text-justify:distribute-all-lines;/*ie6-8*/ text-align-last:justify;/* ie9*/ -moz-text-align-last:justify;/*ff*/ -webkit-text-align-last:justify;/*chrome 20+*/ } @media screen and (-webkit-min-device-pixel-ratio:0){/* chrome*/ .test1:after{ content:"."; display: inline-block; width:100%; overflow:hidden; height:0; } }给input的placeholder设置颜色
::-webkit-input-placeholder { /* WebKit browsers */ color: #999; } :-moz-placeholder { /* Mozilla Firefox 4 to 18 */ color: #999; } ::-moz-placeholder { /* Mozilla Firefox 19+ */ color: #999; } :-ms-input-placeholder { /* Internet Explorer 10+ */ color: #999; }CSS :after 和:before选择器
.clearfix:after{display:block;visibility:hidden;clear:both;height:0;content:'.';font-size:0em}透明度
opacity: .9; filter:alpha(opacity=90)IE7和IE6中opacity是没有用的,在IE6中DIV透明的方法一般用filter;
.haorooms{opacity: 0; cursor:pointer; -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";filter: alpha(opacity=0);}CSS强制换行和不换行 自动换行(word-wrap会判断下一行是否能放下单词,如果能放下此单词则不断行而是换行)
div{ word-wrap: break-word; word-break: normal; }强制英文单词断行(不管单词在下一行是否能单独放下都断行)
div{ word-break:break-all; }强制不换行
div{ white-space:nowrap; }CSS 圆角(border-radius必须放在最后声明,否则可能会失效。)
-moz-border-radius: 15px; border-radius: 15px;textarea禁止拖动
resize: none; //禁止拖动CSS3的一些前缀总结
-webkit /*为Chrome/Safari*/ -moz /*为Firefox*/ -ms /*为IE*/ -o /*为Opera*以旋转为例
-webkit-transform:rotate(-3deg); /*为Chrome/Safari*/ -moz-transform:rotate(-3deg); /*为Firefox*/ -ms-transform:rotate(-3deg); /*为IE*/ -o-transform:rotate(-3deg); /*为Opera*/ transform:rotate(-3deg); /*为nothing*/css3的box-sizing
给了两个并排带边框的div百分比宽度,假如不用box-sizing,边框的宽度会在行内显示。用box-sizing:border-box,可以去除边框的占位。浏览器支持IE9以上及火狐、谷歌、Opera等等。案例如下:
<style> div.container { width:30em; border:1em solid; } div.box { box-sizing:border-box; -moz-box-sizing:border-box; /* Firefox */ -webkit-box-sizing:border-box; /* Safari */ width:50%; border:1em solid red; float:left; } </style> </head> <body> <div class="container"> <div class="box">这个 div 占据左半部分。</div> <div class="box">这个 div 占据右半部分。</div> </div>父DIV设置为相对定位,子DIV设置为绝对定位,可解决元素在页面上的随意布局。
<div style="background-color:red;height:400px;width:400px;position:relative"> <div style="background-color:green;height:200px;width:200px;position:absolute;top:10px;right:10px;z-index:10">层1</div> <div style="background-color:blue;height:350px;width:350px;position:absolute;top:10px">层2</div> </div>固定table单元格宽度
当仅在td中使用<td style="width:98px;">固定宽度在IE中无效,必须在table中加上table-layout:fixed,然后在表格第一行设置td宽度就可以了。CSS的箭头向右样式
<div class="arrow-right"></div>箭头向右 .arrow-right{ width: 0; height: 0; border-width: 5px; border-color: transparent transparent transparent #666; border-style: dashed dashed dashed solid; display:inline-block; *zoom: 1; *float: left; } 利用特殊符号◆ .f_jt{background:#FFE9C8} .f_jt span{color:#FFE9C8;position:absolute;top:64px;left:25px} /*要将三角的color设置成背景色相同。要有边框色彩可以绝对定位两个符号叠加*/固定table单元格宽度
当仅在td中使用<td style="width:98px;">固定宽度在IE中无效,必须在table中加上table-layout:fixed,然后在表格第一行设置td宽度就可以了。html标准代码
