Without having to move icons and menus (plus, there are other elements that aren’t displayed in your screenshots, like the edit counts, the mention to who we replied to, etc…), you can still work on margins as a start:
Default:
.post-menu-area {
margin: 20px 0;
}
Custom:
.post-menu-area {
margin: 0;
}
Comparison:
Moving icons and action buttons isn’t always trivial and could require more in-depth work.
