I'm using a fluid
layout in the new theme that I'm working on for my blog. I often blog about code and include <pre> blocks within the posts. The float: left column for the content area has a max-width so that the column stops at a certain maximum width and can also be shrunk:
+----------+ +------+
| text | | text |
| | | |
| | | |
| | | |
| | | |
| | | |
+----------+ +------+
max shrunk
What I want is for the <pre> elements to be wider than the text column so that I can fit 80-character-wrapped code without horizontal scroll bars. But I want the <pre> elements to overflow from the content area, without affecting its fluidity:
+----------+ +------+
| text | | text |
| | | |
+----------+--+ +------+------+
| code | | code |
+----------+--+ +------+------+
| | | |
+----------+ +------+
max shrunk
But, max-width stops being fluid once I insert the overhanging <pre> in there: the width of the column remains at the specified max-width even when I shrink the browser beyond that width. I've played around with a bare-minimum scenario to reproduce the problem and noticed that doing either of the following brings back the fluidity:
Remove the <pre> (doh...)
Remove the float: left
The workaround I'm currently using is to insert the <pre> elements into "breaks" in the post column, so that the widths of the post segments and the <pre> segments are managed mutually exclusively:
+----------+ +------+
| text | | text |
+----------+ +------+
+-------------+ +-------------+
| code | | code |
+-------------+ +-------------+
+----------+ +------+
+----------+ +------+
max shrunk
But this forces me to insert additional closing and opening <div> elements into the post text which I'd rather keep semantically pristine.
Admittedly, I don't have a full grasp of how the box model works with floats with overflowing content, so I don't understand why the combination of float: left on the container and the <pre> inside it cripple the max-width of the container.
I'm observing the same problem on Firefox/Chrome/Safari/Opera. IE6 (the crazy one) seems happy all the time.
This also doesn't seem dependent on quirks/standards mode.
