>> What I want is to have the row of buttons centered at the bottom of the pageheader.
you can't use
width: 90%;
well, I suppose you can, but that won't center it. It'll just create a 5% margin on the left. to centre it you would need to calculate the width exactly in pixels, and then set
width:295px;
where 295 is however many pixels wide it is.
Note also that this technique is not supported by all browsers, but most modern ones you should be ok.
>> I can't seem to follow the hierarchy of css properties
see
http://www.capesoft.com/docs/NetTalk7/NetWebThemes.htm#CssOrder>> But, if I try editing the theme.css to reflect these changes, and then refresh the page, nothing changes.
correct.
>> (I know -- don't make changes to the theme.css cuz they will be overwritten by the next update -- but I was just testing)
no, they don't get overwritten by the next update, they get overwritten by the next build that runs gzipall.bat. You're trying to do "quick and dirty testing" which is not only harder than doing it correctly, it serves no purpose because the results will change when you _do_ do it correctly.
The correct way is to add the style to your own css file, using an existing css class name if you like. If you just do it right then it's much easier, and may actually work.
