remove header and footer from one page of my website

What theme are you using? Where did you download it from?

It’s a child theme of TwentyThirteen.

Add this to the bottom of your child theme’s style.css file:

.page-id-628 #masthead,
.page-id-628 .site-footer {
   display: none;
}

Wow, thank you! Worked like a charm. I’m wondering though, is there anyway to leave the very bottom of the footer where it says the copyright Amber&Steph…. ??

Thanks again

The purple bar at the bottom

Change the rule to look like this:

.page-id-628 #masthead,
.page-id-628 .site-footer div:nth-child(3)
{
   display: none;
}

Genius. Worked great. Thank you!!
