更改doctype会影响边框和背景 [英] Changing doctype affects border and background
问题描述
我正试图解决让我感到困惑的问题。
以下元素：
#wrapper {border：1px solid＃000; background：#fff;}
使用此DTD时按预期渲染：
<！DOCTYPE HTML PUBLIC" - // W3C // DTD HTML 4.0 Transitional // EN">
但是当切换到这个DTD时：
<！DOCTYPE html PUBLIC" ; - // W3C // DTD XHTML 1.0 Strict // EN"
" http：//www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
无法渲染轮廓或背景颜色。
我缺少什么？

我错过了什么？
DOCTYPE切换。例如参见
http://gutfeldt.ch /matthias/articles/doctypeswitch.html
浏览器对语法错误的宽容度较低，而且一些CSS属性更严格地解释为
使用''现代''Doctype触发Stabdards模式渲染
。

为什么使用XHTML？就个人而言，我会从
过渡到严格，但不是HTML 4.0过渡到
XHTML 1.0 Strict。请阅读：

转到XHTML并发送文本/ html触发怪癖模式
在大多数浏览器上。

考虑自己纠正。只有当<？xml
行出现在DOCTYPE之前时，IE6才会出现这种情况。
I''m trying to get my head around a problem that has me baffled.
The following element:
#wrapper {border:1px solid #000;background:#fff;}
Renders as expected when using this DTD:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
But when switching to this DTD:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
Neither the outline or background colour is rendered.
What am I missing?

DOCTYPE switching. See for example

Browsers are less forgiving of syntax errors, and some CSS properties are
interpreted more strictly, when you trigger Stabdards mode rendering by
using a ''modern'' Doctype.

Why are you using XHTML? Personally I would go from
transitional to strict, but not HTML 4.0 Transitional to
XHTML 1.0 Strict. Please read:
http://www.hixie.ch/advocacy/xhtml for more info on the
problems this will create. Correct me if I''m wrong, but
going to XHTML and sending as text/html triggers quirks mode
on most browsers.

Consider yourself corrected. This only happens with IE6 when the <?xml
line appears prior to the DOCTYPE.
