在写网页的时候一般都先用Div把网页的框架搭好(用不同的背景颜色来区分不同的Div块),然后填充每一个Div,最后把每个Div的背景颜色去掉

    <html>

      <head>

        <title></title>

        <style type="text/css">

          .divIndex

          {
            width:1000px;height:800px;background-color:yellow;margin:0px auto;
          }
          .divLogo
            { width:1000px;height:100px;background-color:red;
          }
          .divContent
          {
            width:1000px;height:300px;background-color:Green;
          }
          .divPicture
          {
            height:300px;width:300px;background-color:Blue;float:left;
          }
          .divText
          {
            height:300px;width:700px;background-color:Purple;float:left;
          }
