[CSS] background image disappears in Firefox when "float:" is used
I have a problem with CSS. Generally, my site looked good in Firefox and
IE7, but then, I wanted to see how it looks in IE6 (which still has over
30% of the market) - the result wasn't that great, the page looked ugly.
So I made various changes, and now the page looks good in IE6 and IE7.
In Firefox however, a background image is not displayed when I add a
"float" element to CSS. Where is the problem?
An example code is here:
http://wpkg.org/cssproblem.html
Expected result: "left column" and "right" column" written on respective
parts of the image. The image is available here: http://wpkg.org/sub2_bg.png
Result: IE6, IE7 - OK
Firefox - image is not displayed
When "float:left;" is commented out in #left_column, the image is
displayed in Firefox (but then, the text in the columns is messed).

It's because your containing div has zero height, because it doesn't
have any contents, except for floats, which don't count.
IE is getting this wrong.
Give #wrapper overflow: hidden and it will grow to the height of the
floats and you will see your background images.
And get rid of width:100% on #wrapper, it's pointless (unless it's for
some weird IE bug I don't know about).

Indeed, I needed "overflow: hidden" - thanks a lot.

Tomasz,
Ben C is right: just get rid of the width: 100% on the div#wrapper:
width: 100% is an useless and pointless declaration in your
stylesheet.

It's not useless - it is a workaround for a IE6 bug - without it, IE6
won't show the background image.
