I didn't keep the banner so the issue isn't viewable on the site. I ended up putting the image in the body of home page.
Bit this seems like an issue anyone could easily replicate and should be fixed by Squarespace.
Hello,
I uploaded a banner image to my site. It is currently on my Welcome page. You can see the Welcome text over the image and it is very distracting. How can I get rid of that?
Thank you,
Chris Reader
