今天有點時間去W3CSchool轉了圈,看了下XHTML相關的,總結了XHTML一些規則,紀錄如下:
l XHTML elements must be properly nested
XHTML元素必須要有正確的結構
l XHTML elements must always be closed
XHTML元素必須被關閉
l XHTML elements must be in lowercase
XHTML元素必須為小寫
l XHTML documents must have one root element
XHTML文檔必須有一個根元素
l Attribute names must be in lower case
屬性名稱必須為小寫
l Attribute values must be quoted
屬性值必須被引號包含
l Attribute minimization is forbidden
禁止屬性簡寫
This is wrong : <input checked>
This is correct : <input checked=”checked” />
l The id attribute replaces the name attribute
name屬性被id屬性取代
Note: To interoperate with older browsers for a while, you should use both name and id, with identical attribute values
l The XHTML DTD defines mandatory elements
必須要有DTD聲明
