Color not painting as required

Hello All,

I'm new to HTML and CSS. I started with a basic design.

This is my HTML code:

And this the code for CSS:

Please let me know why the orange background of "FullPage" is not paiting "Menu_Left" items properly.

Thanks in advance.

 

If you link to your site it can help us out.

 

I'm working this locally. I'm not even able to provide a link to the snapshot or attach a snapshot since I'm a newbie (No access )
Please help me out.

 

I would really appreciate someone helping me on this

 

You put overflow:hidden on that div but it belongs in Full_Page.
