CSS native states and cue decisions quiz

Check what CSS can style around native control state, filtered sibling positions, and WebVTT cues. Each question has one answer and an explanation.

Review the decisions

• CSS ::file-selector-button: style the picker without replacing it
• CSS :indeterminate: show a mixed selection without inventing its meaning
• CSS :nth-child(of selector): count only the rows that match
• CSS ::cue: improve caption contrast without editing the transcript

Other checks

• CSS Quizzes
• CSS type and overlay decisions quiz

Common Mistakes

• Do not mistake paint for validation or submitted state.
• Do not omit a caption track because a cue style exists.
