Vertical align of images in portfolio grid

you can try this – but best would be to have featured images of the same aspect-ratio.

.grid-sort-container .grid-image {
  background-color: #f8f8f8 !important;
}

@media only screen and (min-width: 768px) {
  .grid-sort-container .grid-image img {
    position: absolute;
    left: 0;
    bottom: 0;
  }
}

@media only screen and (min-width: 480px) and (max-width: 767px) {
  .grid-sort-container .grid-entry:nth-of-type(n+2) .grid-image img {
    position: absolute;
    left: 0;
    bottom: 0;
  }
}
