I am starting to use React/Material-UI, and also new to CSS etc... I have a simple page layout with an APPBar. Unfortunately this AppBar overlaps the elements which are meant to go below it.

Another thing is you can't modify a props, you should consider it like a read-only variable.
If you want to listen from the parent to the emitted event into the child component, you have to do something like this
