What it means
Plans are often arranged in cards or columns, with a consistent order for price, included features and the next action. A visitor should understand what is paid, how often it is paid and which differences matter. A highlighted option needs a clear reason for its emphasis.
Use it in practice
Use consistent labels and units across plans. Make billing periods and significant limitations visible beside the price.
Watch out for
A dense checklist can hide the real distinction between plans. Do not rely only on color to show what is included.
