Does meta viewport override fixed element width

I have a simple question related to viewport..

I have a page which has a div with a fixed width of say 1200px..Now i set meta viewport to device-width

So my question is how will the page be rendered now? Will the fixed width of 1200px be respected and viewport will be ignored OR will the device width override any fixed width on the page?

Also will this rendering behavior be same across all mobile browsers?

Just to add, i have already gone 开发者_如何学Pythonthrough the nice article on http://www.quirksmode.org/mobile/viewports2.html

viewport will NOT override fixed width when there is something wider than device's width.

example. css fixed width to 900px; there is an image width 900px in that page. viewport will only wrap the words to device width but not resize layout width. if you remove that image, the viewport may override fixed width.
