css reset重置基础代码
网络整理 - 07-27
css reset,即重置css,也就是重置默认样式。在不同浏览器,HTML中标签的默认样式有一个默认属性值,渲染出来的效果不尽相同,我们在写css页面的时候,为了避免在css中重复定义它们,我们需要重置默认样式,以方便统一,从而提高开发效率,提高样式代码的重用,减少重复代码,减少维护成本。一般调页面的时候都写个:
* { margin: 0; padding: 0; }
方便简洁,但是实际的项目就不要这么写了,因为“*”是全局的意思,即全部标签都要运行这么一句东西,这样开销就大了,一般是采用按所需标签陈列的方式,你用哪些就写哪些,如下:
body,form,div,span,ul,ol,li{margin:0;padding:0;}
下面的是我目前用到的reset
body,form,div,span,ul,ol,li,p,pre,dl,dt,dd,h1,h2,h3,h4,h5,h6,em,a,fieldset,legend,address,label,textarea,select,input,figure,table,th,td,b,i{margin:0;padding:0;}
fieldset,img{border:0;}
ul,li{list-style:none;}
em,i{font-style:normal;}
table{border-collapse:separate;border-spacing:0;}
a{text-decoration:none;}
a:hover{ text-decoration:underline;}
a:focus,input,button,select,textarea{outline:none;}
h1,h2,h3,h4,h5,h6{ font-size:100%; font-variant: normal;}
input,select,img{ vertical-align:middle;}
legend{ display:none;}
textarea{resize:none;}
.clear{ clear:both;}
.clearfix{zoom:1;}
.clearfix:after{clear:both; content:"";display:block;height:0;line-height:0;visibility:hidden;}
