CSS scroll and state decisions quiz

Check the CSS behavior behind reading position, focus, cropping, and visible scrolling. Each question has one answer and an explanation.

Review the decisions

• CSS overflow-anchor: exclude a volatile child, not the whole feed
• CSS display contents: remove a layout box with care
• CSS :focus-within: mark the active field group
• CSS object-position: move a thumbnail crop without changing the evidence

Common Mistakes

• Do not confuse a CSS position cue with focus management.
• Do not let a crop hide the only meaningful evidence.
