Build a Personal Portfolio Webpage - Header Issue

Tell us what’s happening:
Good morning, I am currently working on my personal portfolio page and my heading’s are not appearing and I am unsure as to why. I originally thought that it might be something to do with display: grid but all my sections do not have this property. Any help would be appreciated. Thanks.

They’re there. Just that white font on a white background is really hard to see.
You’ve coded your background rgb(255,255,255) which is white and you coded your h1 headers color: #ffffff which is white.

oh…wow what a silly mistake. Thank you very much for your help!
