Header and footer making problems for mobile

Heloo,

I have a little problem with with wonderful theme Sydney – it’s mostly the parts I can? change with elementor – header slider and footer.
The slider is not looking good on mobile in any form (responsive or not) and the footer makes too long gaps betweeen wingets.
Is there any way to make them pretty? Thank you very much.

Jane.
