The way you have your elements distributed in “Column 44” might make it a bit difficult to position your buttons.
The easiest way would be to add divs so that your text elements and buttons would be positioned within those divs, and then those divs would be positioned within your columns.
The way you have your elements set up, you would have to have the same amount of text in each column to make the buttons sit at the same height.
Here are some quick previews:
All i did was add a div that holds the text elements and a div that holds the button.
Then i tweaked “new div 1” to a minimum height of 600px (usable in desktop mode, not usable in tablet or phone mode).
The minimum height would depend on the amount of static text you want to use. Then ive changed the layouts of the new divs to “flex layout” and i set it to "vertical, centered on both axis.
Then i made all text elements have a max width of 60% (you can change this to whatever you like)
Then it’s just a matter of small tweaks to make the elements look the way you want them to.
Hope this helps ~
