Having problems re-positioning text in poster image

Hi,

I'm trying to re-position my text in the poster image. It's too far down at the moment. I've been trying different codes that have helped others with similar requests on the custom CSS, but none of them have worked. I'm not used to coding, so an explanation for beginners/dummies would be great!

Add to Home > Design > Custom CSS

body#collection-5e4e88e16344df07b00cebc7 .image-card-wrapper {
    align-items: flex-start !important;
}
