From what it looks there could be another component or it’s margin that is creating the overflow.
If you want you can share the link with us and we’ll take a look inside.
I also have this issue. I’ve got a Grid in the footer, I’ve added a container and put the Instagram widget in the container. If I then set the Instagram widget to stretch, it overflows. If I set with to 99% it stays in it.
you should fix the min height and width in order to fix this
That doesn’t work if you set the item to stretch to the fill the container. You can’t control min height of a stretched item. It still overflows.
