Noob

Hello,

I am a noob and am totally lost on how to edit themes. I have searched “edit wordpress.org themes” and similar terms on youtube but have not found decent tutorials that explain the very basics of editing.

Do any of you know of good video tutorials (my preference) or other sites that explain the basics?

Specifically… I am working with the Oxygen theme and want it to look just like the Oxygen theme from wordpress.com (has a header image, white background behind main blog content, etc.) Visual here: http://www.enlightentogether.com
