请问我的HTML5的doctype必须在第一行？ [英] Does my HTML5 doctype have to be on the VERY first line?
问题描述
我一直想知道是否前的DOCTYPE问题，但我似乎空白无法找到网络上的任何明确的信息。人们说，不这样做，但我看不出什么效果，它很可能有，或者即使规范说一定是这样的。我无法弄清楚它是否触发在IE兼容模式或任何讨厌这样。
I've always wondered whether whitespace before a DOCTYPE matters, but I can't seem to find any definitive information on the web. People say not to do it, but I can't see what effect it's likely to have, or even if the spec says it must be like that. I can't figure out if it triggers compatibility mode in IE or anything annoying like that.
原因是，在我的（蹩脚asp.net）code，我更preFER写的：
The reason is, in my (crappy asp.net) code, I would much prefer to write:
<%@ Page language="c#" Codepage="65001" AutoEventWireup="true" %>
<%@ OutputCache Location="None" VaryByParam="none" %>
<!doctype html>
比
<%@ Page language="c#" Codepage="65001" AutoEventWireup="true" %><%@ OutputCache Location="None" VaryByParam="none" %><!doctype html>
由于第一个是整洁。但是，最上面的一个结果是在你的HTML渲染一些空行。
Because the first is neater. But the result of the top one is a few blank lines in your rendered html.
不是一个巨大的问题。如果它很重要，我只是一直在想：）
Not a huge issue. I've just always wondered if it matters :)
