zBench theme, how to customize it

Hello everyone,

I have just installed zBench theme in my site and I am having a very hard time customizing the theme and understanding the CSS stylesheet.

I need to do some basic changes but I can’t figure out how to do this:

1) TOP BACK HEADE / BANNER
How do I change the color of this top back banner? I checked and there’s no background image. I assume it can be changed from the style.css file but I can’t figure out where.

2) & 3) SITE TITLE & TAGLINE
From where do I change the font and color of the Site Title and Tagline. I assume it is from the style.css file but I can’t find it.

4) WIDGET TITLES
From where do I change the font and color of the widget titles that show in the right side column? I assume it is from the style.css file but I can’t find it.

5) CONTENT OF WIDGET COLUMN
How can I remove some of the content of the Widget right column? I have tried to remove “Search by tags” and “Archive” but when I go to Appearance > Widgets, the widget areas on the right are all empty.

6) POST TITLE
From where do I change the font and color of the blog-post title? I assume it is from the style.css file but I can’t find it.

Here’s an image that shows the areas I need to change.

If anyone can give me a hand with it I will greatly appreciate it.

Thank you in advance for your time!
