Divi Theme Image With Title To Call To Action Using CSS

As always, love my daily System 22 DIVI "fix". I have a request in respect of multiple images, blurbs, or Post "snippets" on the same row. How can I ensure that all of them are the same height? By default, they will be the same width (assuming that my columns are the same width) but the height of each is determined by the amount of content. In essence, I'd like the heights to be identical and retain the same aspect ratio across desktop, tablet. and phone.
