Misalignment in grid system with sidebar - html

Question

I'm creating a grid system on a page layout by following the documentation.
My layout causes misalignment when using a grid system with sidebar. The two <div> inside the row are not aligned and appears with a page break. I've playing with col and offset values with no success.

Answer 1

I can see the problem now. You just need to remove the offset classes because an offset is done by increasing the margin which in return increases the element's width and renders the total width of both the sidebar and the dashboard bigger than the total width and thus being pushed down.
Change this:
<div class="col-sm-9 col-sm-offset-3 col-md-10 col-md-offset-2 main">
To this:
<div class="col-sm-9 col-md-10 main">
Here is a working demo with the fix.
