Problem Developing

[tPx]

Hi guys, I'm facing a problem, since the last update I made, I'm the developer of the 4tech theme, and at certain resolutions the forum doesn't shrink properly, for example if you zoom to 150 and 175% on fluid width. My head keeps beating and I don't understand where this problem could come from.

My forum is :  https://tectonicpx.com/board/

Any idea?
