Challenge: Build a Product Landing Page

Link to the challenge:

It’s not the header that needs to be at the top of the viewport but rather the #nav-bar. Your #nav-bar is below the image in the header so it can’t possibly be at the top of the viewport.

@bbsmooth can you tell me what exactly i needed to do?

First, you need to make sure you link the stylesheet into your HTML.

Note: Be sure to add <link rel="stylesheet" href="styles.css"> in your HTML to link your stylesheet and apply your CSS”

It worked! Thank you sir!
