Casper theme - How do I get rid of the white space?

[OneLinerRhymer]

Hi,

I’m new here, just trying to create a simple subscription page for one line rhymes here.

Could someone please help me with how to remove the white space on my page or change it to the same colour?

Thank you

That is the space for the articles. I’m afraid it’s not possible to remove unless you change the theme code…
