FAB link to subscribe section of homepage

Hi, 

I've created a fab which appears on each page of my site ('subscribe to our mailing list') and I would like it to link back to the subscription section of the homepage so users can sign up. 

Can anyone help with the code I need to add so it links to a specific section of the home page? 

I've attached pictures of the button as well as the section of the homepage which I'd like the link to reach.

Thanks in advance!

You mean

Click on Watch button >> Scroll to Sign up form?

Hey, 

No, I meant the FAB on the right hand side of the screen like in this pic:

Is that possible ?

Add a Code Block here > Paste this code

<span id="subscribe"></span>

Change this button code

<div id="book-me">
  <a href="/new-page-1"> Subscribe to our mailing list </a>
</div>

to this

<div id="book-me">
  <a href="/#subscribe"> Subscribe to our mailing list </a>
</div>

Works perfectly. Thank you so much for your help!
