I'm sorry.  This is all turning out to be more trouble than it's worth.  Simply having an mandatory attribution link that points to a page I cannot edit with a bunch of Unsplash images with no context for users is unacceptable.  This makes no sense.  

Arnel, 

• Okay, the CSS resolved the problem with the header, thanks!
• I don't have a Premium BoldGrid account but I did register with a key.  Even if I don't have a Premium account, shouldn't I be able to at least edit the Attributions page?  Currently "thank you" links to this page which is not at all right.  I don't see an Attributions index page I can edit at least from the Dashboard and I don't want to have to go deeper just to edit this page of random photos.  
• I do recall I removed the default background image (the tower against the sky) and replaced it at one point.  But I have no image at all and no background selected now but I don't understand how I can fix this.  (see attached)

Actually, since you replied, there were 2 other things that I'm struggling with ... and they shouldn't be a big deal.  I've deleted the content on the footer, but it still shows the "Special Thanks" link which goes to attribution page I don't want the world to see.  I've tried various ways to fix this, including checking all the boxes that say "hide" and turning off the footer entirely.  But that doesn't seem to have taken.  Also, I've removed the background but it is still showing these grey diagonal lines.  I've tried various ways to refresh and resolve this and it doesn't seem to work at all.  These should be pretty simple things.  I'm wondering if there's something about this that is not being published live for some reason??  Don't know. 

Hi Arnel, 

Thanks for getting back to me.  The URL I'm referring to is www.thecatsquad.com.  You can see about 10px of blue at the top, which is what's left of the header after I deleted all content.  I dropped a block in below that to act as a sorta header since this is just a one-page site.
