I'm trying to get IE9 to load my page with IE9 standards...
I noticed having <!DOCTYPE HTML> puts the damn thing into quirks mode... Which pretty much breaks everything on page...
How do I get IE to stick to IE9 Standards?
回答1:
Placing:
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
in the <head> tag should do it.
回答2:
Make sure you don't have any HTML comments before the DOCTYPE declaration otherwise it will trigger IE9 to use quirks mode.
Just having <!DOCTYPE html> at the very top of the page with nothing preceding it should be enough to make IE9 use standards mode. You shouldn't need the meta tag as well.

Using the WebBrowser control to display HTML will use IE8 rendering, regardless of doctype, unless you specify
<meta http-equiv="X-UA-Compatible" content="IE=9" />
or
<meta http-equiv="X-UA-Compatible" content="IE=edge" />

Remove any unsupported comments, check for ie supported comments. And place in your head tag. The doc type declaration should be the very 1st line in your HTML.

I have in the head mentioned in all the pages. However it is just showing correctly for the home page for all other pages the page is still rendered in scattered mode.
