Responsive issues

Hello,
In the responsive version (on mobile):
1 : i’d like to make the logo bigger, and reduce the space between logo and menu.
Because currently it displays a tiny logo, then a huge blanck space and then the menu..

2 : Titles words are often cut. Is there a way to make it responsive ? For exemple it display :
“THERE IS A PROBL
EM THERE”
I’d like to display titles like this :
“THERE IS PROBLEM
THERE”
or
“THERE IS
PROBLEM THERE”
But i don’t want the words to be cut.

Thank you in advance for your help !!
