Question

I need to align my buttons to the same height. I already changed the height of the columns to the height amount of the longest column (493px). I just need to move the button down, so that it is at the same height of the longest column.

.col-sm-6.col-md-4.boxes {
    background-color: red;
    height: 493px;
    /* height: 100%; */
}

Answer 1

May be this will work for you.

.col-sm-6.col-md-4.boxes {
    background-color: red;
    height: auto;
}

Answer 2

I would suggest using bootstrap built-in classes. No need to set absolute pixel values. With the following classes the column will automatically adjust to the taller one.

Give <figure> elements these classes :

h-100 to set their height to 100%.
d-flex to set them to display: flex
flex-column to set them to flex-direction: column.

Then give panel-body the class flex-grow-1 so that it fills all the available space and pushes the footer/button down.

Then, for better style, give a margin-bottom (such as mb-3) to .panel-footer

.col-sm-6.col-md-4.boxes {
    background-color: red;
    height: 493px; /* kept for height */
    /* height: 100%; */
}
