Need Help with Blogger Template

Hi,
Need some help there.

I'm trying create blog (Blogger) with simple design but I'm noob at this.
I have looked for free templates but they all are craps and now trying create by myself but can't find some things how to get done.

1. Now Im trying edit horizontal menu bar. How can add background color and other cool staff to this:
<nav>
<ul>
<li><a href=?/?>Home Page</a></li>
<li><a href=?/about-us?>About Us</a></li>
<li><a href=?/contact-us?>Contact Us</a></li>
</ul>
</nav>

2. How can resize Outer-wrapper? I can't find it in html code.

So far I need get done these two things then can move forward.

You do that with CSS.

You can learn it all on this website: http://htmldog.com

By outer wrapper, do you mean the background image? You can create your own image on MS Paint or Photoshop or other photo editing software. Save it and store it in some photosharing sites like photobucket. Extract the codes from these sites. Use css codes to call the image from the photosharing site. Best of luck!

The best way to get started in blogger is by using the default templates. Believe me these templates can be customized up to 100% and you will not be able to tell if this is default template or not.
