常用css 清零样式 清楚浮动等样式。(+Bootstrap的全局样式)
这个东西没有一个标准答案,网上的不一定适合自己的项目,一般是下载一套标准的css reset,然后在此基础上根据自己实际情况去删改的。适合自己的以及项目的才是最好的。
目前比较有名的是:

上面的只是清零样式,没有清除浮动以及其他的样式,慕课网版本的较全。也可以用这个;
下面的是慕课网的清零清除样式文本:
body,ul,ol,dl,dd,h1,h2,h3,h4,h5,h6,p,input,select,textarea,form{margin: 0; padding: 0;}
body{font:14px/1.5 "宋体";}
img{border:none;}
ul,ol{list-style:none;}
input,select,textarea{outline:none;border:none;background:none;}
textarea{resize:none;}
a{text-decoration:none;}
/清浮动/
.clearfix:after{content:"";display:block;clear:both;}
.clearfix{zoom:1;}
选择
::selection {background-color:#669900; color:#ffffff; text-shadow:none;}
::-moz-selection {background-color:#669900; color:#ffffff;text-shadow:none;}
去掉a的下划线
a {blr:expression(this.onFocus=this.blur())} /if IE/
a {outline:none;}/if 火狐等现代浏览器浏览器/
省略号
white-space:nowrap;overflow:hidden;text-overflow:ellipsis;
英文自动换行
word-break: break-all;
强制不换行
white-space:nowrap;
contenteditable="true"
clearfix完整版
.clearfix:before,.clearfix:after { content:""; display:table;}
.clearfix:after{clear:both;}
.clearfix{*zoom:1;}
expression(this.onFocus=this.blur())

这是慕课网上的Bootstrap的全局样式。其实貌似每个人都有自己的习惯,可以根据这些设置自己常用的样式。
在制作Web页面时,前端人员都习惯为网站设置一个全局样式(reset.css)。那么在Bootstrap框架中也不例外。Bootstrap框架的核心是轻量的CSS基础代码库,他并没有一味的重置样式,而是注重各浏览器基础表现,降低开发难度。大部分前端人员都具有归零的思想,但实际你会发现,归零之后的样式在开发过程中会存在着潜在的问题,例如,在全局样式表中将em变成一个普通标记,明明应该是斜体,怎么就没效果了呢?
Bootstrap框架在这一部分做了一定的变更,不再一味追求归零,而是更注重重置可能产生问题的样式(如,body,form的margin等),保留和坚持部分浏览器的基础样式,解决部分潜在的问题,提升一些细节的体验,具体说明如下:
移除body的margin声明
设置body的背景色为白色
为排版设置了基本的字体、字号和行高
设置全局链接颜色,且当链接处于悬浮“:hover”状态时才会显示下划线样式
