Remove blank space between posts

[eolic 0]

Hi, Using PlatformPro with Magazine Style, I have the two firsts posts with full width, and under it, the clip ones. I would like to reduce the blank space between the two thumbnails, that I changed the size. I would like to try with the minimum space and with no space at all and then choose the one i prefer. Thank you very much

Hi eolic, Do you have Firebug installed? It will help you pinpoint which CSS styles are being applied, and which elements you need to change. If you're still having difficulty, please provide a link to the site.
