Problem with colborder / Site Layout

[Alex S.]

Hi there

Some days ago I downloaded the latest release of BlueprintCSS and I
keep running in the following problem: Colborder "breaks" my layout.
I'm using the standard 24-column grid as it came out of the box.

Code like this drops the content area (the second column) in the next
row:

---------- Snip ----------

<!-- should be column 1 -->
<div class="span-5 colborder">
<div class="box">
a login box
</div>
<blockquote>
the typical lore ipsum
test text
</blockquote>
<p class="box">
another test text
</p>
</div>

<!-- should be column 2 -->
<div class="span-18 last">
... main Content Area
</div>

------------------------------

I can't find the reason for my problem. I even copied the sample
page's sources and the behaviour is the same. It sems like the
colborder uses a bit too much space.

I'm grateful for every clue

Alex

Note: BlueprintCSS is just awesome for guys like me that love coding
(and are very used to it) but aren't web designers. Thanks guys for
the great work!
