The spacing after blog post images has changed with the last WordPress update. Now it has not any space. I have read in another thread that I can add this CSS:
`figure img {
margin-bottom: 1.5em;
}
It works well but not after youtube videos (I don’t know the selector of youtube videos).
Besides it, if you write a description where WordPress says “Add caption” the margin is created before the description, and it should go after it, otherwise it looks strange.
