Equal Height Sidebar Right
Each vertical post-card has the same height, regardless of whether it contains a lot or little text, whether the post has an image or not. The sidebar is on the right. If no widgets are active in the sidebar, the grid take 100% width.

Post without image but with a longer heading to fill the card
This beautiful post has no featured image. It is only there to show how it fits into the cards, which are all the same height if posts displayed in an equal-height grid. The Read more link is always on the bottom of the cards. So you should fill the content with text to avoid whitespace.
