Trouble trying to displaying posts inline with css

On this page here (single.php)…
http://www.perthmetro.net/patio/fencing-gates-perth/aluminium-pool-fencing-gates/
Mid way down the page, under the heading “Check out our other Fencing + Gates” there are 2 posts represented by thumbnails that are INLINE.

Now check out this page (archive.php)…
http://www.perthmetro.net/patio/products/fencing-gates-perth/
At the top of the page under the heading “Fencing + Gates” there are 3 posts represented by thumbnails that ARE NOT INLINE.

Both sets of posts use the code and css, but obviously there is some css that is stopping the latter posts from displaying inline.

If someone could be kind enough to help me with the css needed to get them inline then that would be much appreciated.

Thanks, Pete
