论前端css初始化的重要性

新手,求喷,刚刚知道每个浏览器都有对 标签的初始化,就造成我们网站开发者开发的web程序,会在不同的网站上有不同的样式风格,这给用户带来了很不好的体验,这也是浏览器本身的原因造成的,这时候,我们不可能过多的去限制用户的自然选择,所以我们只能优化我们自身的代码,使得我们的web程序兼容性更好,这就需要我们对一些常用基本的标签进行初始化,下面是可以借鉴的几个门户网站的css初始化代码:

  1. 腾讯QQ官网 样式初始化
    1 body,ol,ul,h1,h2,h3,h4,h5,h6,p,th,td,dl,dd,form,fieldset,legend,input,textarea,select{margin:0;padding:0} 
    2 body{font:12px"宋体","Arial Narrow",HELVETICA;background:#fff;-webkit-text-size-adjust:100%;} 
    3 a{color:#2d374b;text-decoration:none} 
    4 a:hover{color:#cd0200;text-decoration:underline} 
    5 em{font-style:normal} 
    6 li{list-style:none} 
    7 img{border:0;vertical-align:middle} 
    8 table{border-collapse:collapse;border-spacing:0} 
    9 p{word-wrap:break-word} 
  2. 新浪官网 样式初始化

     2 body{background:#fff;color:#333;font-size:12px; margin-top:5px;font-family:"SimSun","宋体","Arial Narrow";} 
     3  
     4 ul,ol{list-style-type:none;} 
     5 select,input,img,select{vertical-align:middle;} 
     6  
     7 a{text-decoration:none;} 
     8 a:link{color:#009;}

     2 body, button, input, select, textarea { font:12px/1.5tahoma, arial, 5b8b4f53; }

     7 ul, ol { list-style:none; }

     9 a:hover { text-decoration:underline; } 
    10 sup { vertical-align:text-top; } 
    11 sub{ vertical-align:text-bottom; } 
    12 legend { color:#000; } 
    13 fieldset, img { border:0; } 
    14 button, input, select, textarea { font-size:100%; } 
    15 table { border-collapse:collapse; border-spacing:0; }
