How can I make two columns having the same height in Bootstrap grid columns?
.item-text {
  padding: 30px !important;
  /* Flex center. */
  display: flex;
  align-items: center;
  vertical-align: middle;
  justify-content: center;
  border: 1px solid blue !important;
}
.item-text .item-center {
  align-self: center;
  margin: auto;

      <p class="item-description">(Short description) Remix-remake of John Berger’s 1972 BBC documentary, Ways of Seeing</p>
