4 Image/text containers not staying equal in height


I have a site: https://www.congcamping.com/ On the home of the site there are four categories of the product that have text and an image. For some browser sizes these boxes are all the same height/width, but for some configurations one of them might change height and show as being longer or shorter than the three. I understand this is because of the responsive code, but is there a way I can make sure that when all visible together they keep the same dimensions?

Many thanks,
