Align elements to bottom of repeater

I have a simple repeater in my website.
My question is how to make a line stick to the bottom? Or alternatively, how can I enforce that the text will expand above the line.

The question is not clear enough because it’s hard to understand from this screenshot where exactly the repeater is and which elements belong to the repeater items.

I’ll try to be clearer.
Everything here is inside the repeater, including the lorem ipsum paragraph and the line that goes across it.
I want the lorem ipsum paragraph to be above the line, which again all belong to the same repeater.

So put the line close to the bottom of the text element + group the text and the line (select both > mouse right click > group).
