Hey guys
I'm finishing the code for the JSC with free code camp and need a bit of a hand
1 Numbers flow through the borders if many
2 Dots will keep printing if we strike the point key
3 For the iPad and smartphones the design of the page is twisted and choked

Please help me out with these little bugs

Answer 1

Add 'overflow-x: hidden' in class named 'display'. this will solve your first two problems. For third problem you should add media queries.

Answer 2

Thx a lot!
