Quick info about parent selector in CSS4

! - determines subject of selector according to CSS4 reference

E > F - selects an F element, child of E

E! > F - selects an E element, parent of F

Parent

Any vaild selector is okey, id, class, even like this one: input[type=checkbox]

Target

This is optional, after we've got PARENT of our CHILD selector, we look for this TARGET element within PARENT.

Child

Based on this, we select PARENT element.

State

• changed, selected
• checked
• focus
• hover
• click
• dblclick
• active
