中华家教吧官网首页标准化验证Passed

这两在做中华家教吧页面的web standard validation.

终于成功了，演示地址： http://www.zhjj8.com/

CSS也验证到了CSS 2.1版本。

时间主要浪费在：

  1. 要将网址链接中的“&”改成“&” 才可以。
  2. 所有HTML都要小写
  3. 所有HTML的标签的属性的值都要加“”，如 width=”30px” 而不可以 width=30
  4. <img 标签需要有 alt ，就算是没有任何意义的，也需要改成 alt=”", 最好要合上标签 即  “/>“

下面摘录一些别人标准化页面时的记录：

  • Invalid entry was found in the value for the “href” or “src” attribute
