How to make Bulma card images same height inside columns of different width?

Question

I am trying to make two cards inside columns of width 7 and 5. I want to have the card images same height. How can I achieve that?

I have tried classes like is-fullheight and set the card height to 100%, but it does not work that way.

            <div class="columns is-fullheight">
                <article class="column is-7">
                    <div class="card is-fullheight">
                        <div class="card-image">
                            <figure class="image is-4by3">
                                <img src="https://bulma.io/images/placeholders/1280x960.png" alt="Placeholder image">
                            </figure>
                        </div>
                        <div class="card-content">

                                    <figure class="image is-48x48">

The height of the two columns differ. The image of column is-7 is a lot bigger.

Answer 1

Bulma scales the images according to the column width. Therefore the height gets automatically adjusted, when the width differs.

You can simply set a fixed height for the image as well as the .card-image class, but keep in mind, that this will scale the images and affect the aspect ratio (I don't know, if thats the wanted result):

.card .card-image,
.card .card-image .image img {
  height: 200px;
}
