Hi
I am using the template "Giver" - and have some problems with configuration:
How do I make the blog media field have a smaller height and change the color of the green field ?

My content (the text) goes all the way to the edge - and I don't think that looks nice. Is it possible to configure a margin - only on the text and not on all other content?
My hamburger menu is white and cannot be seen clearly on mobile. Where do I change the color?
When the front page loads, a green square appears briefly in the background. What is that?
Best regards
Charlotte
