CSS property decisions quiz

Choose the property that preserves the component's content and interaction contract, then inspect the linked lesson for the boundary case.

Review the lessons

• CSS box-sizing: include padding and borders in a declared size
• CSS margin collapse: explain vertical gaps before changing them
• CSS grid template areas: name regions without rewriting document order
• CSS background size and position: crop decoration deliberately
• CSS form appearance and accent color: retain native behavior

Common Mistakes

• Do not use a visual fix to hide a document-order defect.
• Do not treat a parsed declaration as proof it is appropriate for the content.
