Silly problem with my 3 column stack

my 3 column stack is acting funny
its on my hompage right under the banner. For the life of me I cant figure it out.
Any insights appreciated

below the banner, the 3 columns are not equally spaced - two of the columns are on the left, then there is a big gap and then the last column. in rapidweaver preview it looks fine. And the settings appear to be fine.
This is not my first site - i dont consider myself a newbie, but im still stumped!
Ive tried chrome & safari browsers and it looks funny in both.

Figured it out - i had to change the site width to “full” and now all is well
