I would like to add a video to my website homepage that automatically plays when someone gets onto my website.

If you look at the main page for Squarespace right now, you will notice that there is a video playing in the bottom right corner.

Website Builder — Create a Website in Minutes — Squarespace

Can anyone provide me with code needed in order to add a video just like this?

I am looking for someone who can help me with making adjustments/edits to the mobile menu of this website.

There are a few things I would like to do:

1. Make the black button at the bottom less padded (reduce the amount of black/space around the text)
2. Update the font within the button to Montserrat
3. Add another button 
4. Add text
5. Shift the menu items to be top aligned.

Can anyone help me make this adjustment?
