Heights: How can I make a series of button widths the same regardless of text?

I'm trying to make a LinkTree workaround on my page.  It's so simple it's stupid not to -- EXCEPT I don't know how to make the width of every button uniform (and appropriate for mobile viewing). 

Bonus: Getting rid of navigation tabs for this page only.

Here's the page: https://www.homegrownfit.com/learn-more

Thank you!
