我有一些HTML来制作我开发的软件的期望输出。我已经确认（尽我所能）文件的格式正确，但是当我在Chrome或IE中打开它时（也可能出现在其他浏览器中），浏览器会更改提供给我的错误输出的HTML。浏览器修改我的HTML，导致不正确的输出
我创建的HTML是：
<!DOCTYPE html>
<html>
<head>
<style>
*{margin:0;padding:0;vertical-align:top;text-align:left}
table{border-collapse:collapse;}
</style>
</head>
<body>
<table style="margin-left:15pt">

<table>

<td style="width:315.43pt"/>
<td style="text-align:right;width:118.93pt;height:12pt;font-family:arial;font-size:10pt">

This text represents the contents of the email.
<br/>
<br/>
Blah Blah

<br/>
Bibble.
<br/>
<br/>
Note how the line breaks get stripped from the text!

HTML format Text Boxes nearly get the formatting right (the Viewer is missing multiple breaks)!

我知道这个输出是很多嵌套表，但我试图将一个不确定的输入类似于一个单词文件，并正确地将其呈现为可以通过电子邮件发送和显示的HTML。我只是想知道为什么浏览器改变了这样的html，如何阻止它这样做，如果我能够发送一个电子邮件与我的HTML浏览器仍然修改输出时，通过网络邮件查看？
我不认为这种改变浏览器自己做。您是否清除浏览器缓存并再次加载网站？ –
请描述你改变HTML的含义。你也不能把'table'作为'tr'的直接子对象，必须是'tr> td>表' – Justinas
你的HTML首先是无效的。所以输出绝不是不正确的。 – BoltClock
