remove blog text title area from theme

Hi i am using the raindrops theme, i checked their support site and it was all in chinese or something. So i thought i would ask here.

the blog is https://www.durangodaves.com/blog

where it says the title text at the top durangodaves blog, i know how to remove the text in the settings but the dark background space is still there, i tried commenting out some stuff in the header php but did not work.

question. Any idea how to remove the dark background box at the top of the page after i remove the text title from settings?

Does the text title have anything to do with the SEO, i dont have to have it do i?

If i must have it then how to i make it really small so that its not obtrusive?

Thanks
