关于DOCTYPE 引发的样式问题_html/css_WEB-ITnose

Jun 21, 2016 am 08:48 AM

今天改了一个bootstrap的页面,加入了如下代码,

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml">
Copy after login


然后页面就有问题了,对齐不了,如图所示





去掉之后,改成如下
<!DOCTYPE html><html lang="zh-cn">
Copy after login


即可对齐了,请问这个是啥情况?

show your whole code

这两个文档声明使得浏览器使用了两个不同的方式来解析文档,长的那个是使用xhtml的标准,短的那个使用html5的标准

还是贴一下全部代码吧。
楼上说的那个应该不对 你写的这个是HTML5声明的完整写法 是HTML5声明的简略写法
参照http://www.divcss5.com/html5/h701.shtml

html5的完整声明写法?html5我貌似只记得有一种写法吧,而且html5的声明会用到xhtml的dtd?
