Computing and Displaying Discounted Prices in CSS

CSS math enables calculating and displaying dynamic values like discounted prices without JavaScript, reducing latency and browser resource usage.

• •The attr() function with type parameters allows CSS to read and parse numeric values from HTML data-* attributes as numbers, not strings
• •CSS calc() combined with attr() enables direct price calculations using formulas like calc(attr(data-price number) * (1 - attr(data-discount number)))
• •CSS counters convert calculated numeric values into displayable content, with mod() and round() functions handling decimals
• •The :has() selector conditionally applies calculations when a discount checkbox is checked
