Hi guys,

I have recently taken over control of this website and am having some issues throughout. Lots of items change across the website when only changing one item etc.

Anyway, at some point the images on the ‘featured projects’ page become very small. I have attempted to adjust them but I can’t seem to. I can only make them smaller or change the height.

Could someone tell me whats going on?

I’ve also noticed things like buttons move position everywhere on the website when changing it on just one page. Is this a simple fix?
