Product landing page project help please

Tell us what’s happening:
I can’t complete three tasks:

  1. The navbar links should take me to a corresponding part of the page(I already did that with the file I saved).
  2. Clicking the #submit element sends the email to a mock url which is: https://www.freecodecamp.com/email-submit (again, I put that but it won’t work)
  3. The navbar should always be at the top of the viewport.
    I hope that’s not too much, thank you!

Challenge: Build a Product Landing Page

Link to the challenge:

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).

  1. Your hrefs should have a link that navigates to a section of the that same page for example if I want to navigate to the the video I use the video id like:
href="#video"

If I click the link, I will be taken to were the video is.
2. This link: https://www.freecodecamp.com/email-submit--->
You’ve have to use it as the link for the action attribute on the form.

Got it thank you very much!
