Hello, I am having trouble making my site's header transparent. I've watched just about every tutorial on youtube and followed the instructions to the tee on everyone, but can't seem to get my header to go transparent. It sometimes looks that way after I edit it in the Elementor editor but when I pull up the site there is always a black bar under the main menu that I just cannot get rid of. And the crazy part is it only appears every now and then, and doesn't on my mobile site. Any suggestions?
