Darken background behind Titel

Hi everybody,

Im just working on setting up a website with the Illdy Theme, and I need to darken the background behind the Title and Titel description, so it is readable against my background image. Is there a way to do such a thing?

Also while typing in my domain into the address bar, I realized that my website comes up having the word “Blog” added to the Titel. Is it possible to remove that word?

Here is a link to my site: www.rolandsgardenguesthouse.com

Thank you
