Webpage on different Browsers looks different

[Manuel]

Hey,

I just started on GWT and used the GWT Designer to create a Website.
It uses DockPanel (North, South, West and Center). Dock Panel should use 100% width and height.

After compiling it, it looks just like in developmode on Firefox, but on other browsers the Webside looks bad, i.e. it doesnt use 100% height.

I thought due the permutation for each browser this wouldnt happen?

Regards,
Manuel

I believe that problem is generated css that is correct for Firefox, but looks different in Chrome and IE. Try to find out (on the google) how to fix that differences.

Agreed. The focus must be on CSS.
