CSS Adjacent Sibling Selector
element1 + element2
This selector allows us to select an element which follows after its sibling-element in the document (p and p are siblings, ul and ol are siblings, h1 and h2 are siblings...). Plain text is ignored (elements aren't ignored). Only elements and their position in the markup structure matter.
