Website overflowing

Hi my site is overflowing (for example on window size 1530x1200px) I have no idea why and how to fix this :confused: I guess the issue is the grid
I am talking about already published site Meet React and React Native experts {callstack}
Any ideas how to fix that?

Here is my site Read-Only: **Webflow - Callstack Website

Fixed widths on elements inside a collection list create problems like this.

hmm but I need to have fixed widths there :confused:

Not if you want responsive designs. I suggest you review Turn a collection list into a responsive grid | Webflow University for more info if you haven’t.

It is a grid and still doesn’t work properly :confused:
