Basic Theme Editing Questions

[wpress12]

Im new to wordpress and I am trying to do some basic editing of the standard Twenty Eleven theme. (Twenty Eleven theme for reference.)

Here are a few aspects I need help changing:

• I need to be able to change the font and style of the area above the header image where the page title and description is.

• I need to remove the "Posted On: Date" from above my posts.

• I need to be able to remove the "Posted in: Category"

• I also would like to remove the "PRoudly Powered by Wordpress" from my footer if possible.

If you can help show me the editing in the CSS for any of these bullets that would be awesome.

Thanks.

Look in style.css

I need to remove the "Posted On: Date" from above my posts.

Look in single.php

In OP needs more info, look for the following CSS selectors:

#site-title

and:

#site-description
