Gaps in product listing

Hi,
Enjoying working with Hikashop and have learnt from this forum. I'm having some trouble with the display of products within and accessed from a category listing.
So I have categories and sub-categories, boys clothing -> suits/shirts that sort of thing.
I have a page which loads a hikashop content module. Type of content is category, layout is div, no. of columns is set to 3 and number of items 20. Associated category is top level (product category) and menu is categories listing.
I then see the two top level categories - no problem. I click on one and I then see the three categories under that, no problem. I click on one of them and I get a list of the products on that category. All working except in the one sub-category which has five products I seem to have a gap where two products could fit?
I tried disabling bootstrap on that page and they list on top of each other with no gaps so guess it's going to be down to my template and bootstrap, but I checked in firebug and it all seems fine?
Any ideas?
Thanks

Hi,

We'll need more information like a little screenshot of the problem that you are having for example, and a link to your page will probably help us to know that's a CSS issue or not.
thanks .

Thanks for coming back so quick.
There should now be a screen shot attached to this post.
Here is a temporary link to the site I'm using to develop the site: tinyurl.com/kq74788

Hi there,

This is just a small css isue.
Since your product title are somethimes longer it "pushes" the product under the top ones.
Adding a css rule like this one in your front end css file should do the job (System>Configuration>Display>css):

I don't know why but setting the font-size to 16 px is fixing the problem, so you'll just have to use this kind of CSS code :
