If the container has a fixed height matching the logo element height, you can set overflow: hidden. Anything wrapping to the next line will be out of view.
Not sure what you’re trying to do with your layout but Clients Wrapper 3 has -220 margins and 147% width, so your logos are not going to respect your flex wrap child the way you’re describing.
You should probably rebuild that element so it’s with the visible area of the page.
I’m on a speaking tour for a week, so I won’t be able to look again- but the setup is simple.
Make sure your your outer div fits the page width, and is overflow none. Make your inner div flex, horizontal, with children wrapping. set the inner div’s height to a specific measure like 3rems, and the logos to the same height as that div.
That’s the simplest layout that should accomplish what you want at all breakpoints.
