I created a Test Page: http://teamsfirst.ca/test-columns/
Row-Fluid seems to work fine – Row (which is what I was using) is shifted 25px to the left.
I will try to answer my own question…
Row – uses pixels – which assumes a container of a fixed width (1024?)
Row-Fluid uses percentages – so it works fine in JS because it can adjust to the 980 w container
TB uses Row-Fluid (as it should) so it matches the row/fluid – the mistake I made was using ROw.
