>> I'm trying to get the blue area on the header so that the entire header area is covered with blue.
It is hotpink right now - the body color. Style the header div.
>>I also would like to have my name on top "Citrine" so that the title appears like this: "Mimi
This is probably on the header template, you will have hack the html for the Title tag.
>>The word Citrine should be larger than my name as well.
Style - possibly using a span. Depends on html in previous complaint
>>And my tagline should be on the far right.
Style the #desc id
>>By the way, can I remove the about me picture on the right?
Yes, of course you can. It's your website.
How to do it is a different matter. And that depends how it is coded. It is a custom theme. You will have to look into it yourself. It is either a widget or sidebar template code.
>>No one answers my questions please reply!
It appears that you are pretty new to this and are asking others to customize your template for you.
If you are new, I suggest you start with the builtin default kubrick template until you understand how the template, css styles, widgets and plugins work together. Then branch out into customization.
Or hire someone.
Good Luck - Keep at it
BTW - Firefox and Firebug are your friends!
