koo145 on "sidebar pushed to the bottom of page on only one post"

Hi. the following page is displaying the sidebar in the very bottom:

It's only happening on that post and I'm having trouble figuring out why. The only difference between this post and the others is that this post has a square ad and a separator on top.

Can anyone shed some light on this? I would really appreciate the help.

the problem exists in all pages of your site - it is possibly not showing because your browser is working with old cached stylesheets (?)

you added a fixed width to the style of .col-md-4 in style.css of the child theme.

.col-md-4 { padding: 20px 0 0 40px; width: 330px;
}

why would you want to do that in a responsive theme?

How should I style it then such that the column retains a similar style?
