How do I make a "burger" style menu tab for my home page?

So I'm trying to streamline my website by creating a burger menu or pull down menu on the home page. a sort of all in one button where when it's clicked on you get the option of "about me" or "services offered". So far im only finding the one "button" option and it doesnt seem to have any effect on the mobile edits even. Thank you in advance for your help and input!

Hi,
