I'm currently working on revamping the appearance of the header area for this website. My goal is to replace the background image with a rectangular JavaScript ad positioned to the right of the logo. However, I've encountered difficulty due to the complex series of div blocks within the header. Any content I try to place next to the logo often ends up underneath it rather than alongside it, regardless of its size. It's puzzling because there appears to be ample space to the right of the logo. I'm unsure of what the issue could be.
