Top & Bottom Justifying Poster Text

Site URL: https://alisha-trahms.squarespace.com/introduction

I am using the Foster template and am looking for code to adjust the position of text on posters top to bottom. I've found several places on the inter webs where people talk about left-right justification (which is already available in the style editor), and top-bottom justification for banners, but nothing much for top-bottom justification for posters. Does anyone know how to do this?

Additionally, does anyone know how to add a frame on top of posters? 

Add to Home > design > Custom CSS

body#collection-5e84e35d56e5f802dd6b8f7e .image-card.sqs-dynamic-text-container {
    bottom: 0;
    position: absolute;
}

Hey there @tuanphan, thanks for the help!
