The CSS grid system is one of the things that makes Montezuma so great and so flexible. The documentation is clearly laid out in:
Dashboard > Appearance > Montezuma Options > CSS SettingsThe 2 key things are:
- Surround your column divs in each row with row div's, such as:
HTML Code:<div class="row"> <div class="col3">...column on the left, 3 "units" wide...</div> <div class="col6">...column in the middle, 6 "units" wide...</div> <div class="col3">...column on the right, 3 "units" wide...</div> </div>
- Your col divs in each row have to add up to 12 units wide.
Experiment with a test template and a test page. Make a new template called something like test. Give your test divs each a different background color, such as:
HTML Code:
<div class="row" style="background:yellow;"> <div class="col3" style="background:red;">...column on the left, 3 "units" wide...</div> <div class="col6" style="background:blue;">...column in the middle, 6 "units" wide...</div> <div class="col3" style="background:green;">...column on the right, 3 "units" wide...</div> </div>
Here's an even more detailed post by Juggledad that shows how to put a sidebar in the left side.
