Add buttons to a toggle Menu

I would like to add a “Read More” button to a toggle menu I have created using the Socha theme.

Here is a link to the page I am working on… barely anything works on it yet, still heavily under construction:

I created the look I want with ‘inspect element’ and have included a link to that too:

I am brand new to word press, and could really use some help with this. Thanks in advance!
