Bottom-align slides' text and button in #Brooklyn theme
Disable the parallax effect applied to your hero slideshow by changing the line {% assign hero_parallax = true %}
to {% assign hero_parallax = false %}
in the snippet file hero.liquid. With parallax enabled, the bottom-aligned content would disppear as you scroll down.
Add the below CSS at the very bottom of your theme.scss.liquid file:
.hero__text-content {
vertical-align: bottom;
padding-bottom: 50px !important /* To leave room for the slideshow navigation */;
}
