When trying to align content to the bottom of a column, use flex.

 	<li>Make sure your row has the <strong>equalize heights</strong> option turned ON.</li>
 	<li>In the <strong>column</strong> you wish to align the module to the bottom, add in the custom CSS box:
display: flex;
flex-flow: column;</li>
 	<li>In the <strong>module</strong> custom CSS box add:
display: flex;
flex-direction: column;
justify-content: center;
flex-grow: 1;</li>

To align the content to the bottom or top just change the css in step 3 to:
justify-content: flex-start; (for top)
justify-content: flex-end; (for bottom)
