Recently, I'd like to modify the logo on the web page using sitebuilder, but the background banner cannot align properly with the logo, no matter how big (width and height) the file is. It show up as some misalignment. I've compared the page source of my current live web page, and the 'preview' page, and I've found the only difference between the two is the first line of the file. which is "DOCTYPE HTML 4.01 Transitional", when removed it from page's source code, the logo alignment problem disappeared. I tried more than template same problem, don't know what's wrong.
