Hi there,
add this CSS to your site:
.align-bottom > .gb-inside-container {
height: 100%;
display: flex;
flex-direction: column;
width: 100%;
}
.align-bottom > .gb-inside-container > :last-child {
margin-top: auto;
}
Then edit your Query Loop, select the Container Block ( Post template ) and in Advanced > Additional CSS Class(es) add: align-bottom
you may need to add your Date and Author meta headlines in there own container to keep them inline.
