[SOLVED] Dashed lines in Page Menu Bar

I tried adding a html/css insert that I found on a previous forum post to eliminate the dashed gray lines around the page menu bar. Here is what I inserted:

div#menu1 {
border: none;
}


Now if you notice at my site (www.kimberlygill.com) it appears that my header image is being affected. Check it out and let me know if you see an error in the code I entered. Thank you.

Best,
Kimberly
