Understanding the HTML Structure
The comparison table uses a semantic structure with data attributes for JavaScript targeting. Each column is wrapped in a div with a data-plan attribute, making it easy to identify and manipulate specific pricing tiers.
The key structural elements include a wrapper div for the entire table, individual column containers, header sections with pricing, feature lists and action buttons. This modular approach ensures maintainability and scalability.
CSS Approach and Styling Strategy
The CSS uses a mobile-first approach with flexbox for responsive column layouts. Hover states are managed through the .column-hover class, which applies a subtle transform and shadow effect to create visual feedback.
The .best-choice-active class provides a persistent highlight with a distinctive border and background color. CSS transitions ensure smooth state changes, while custom properties enable easy theme customization. The design prioritizes clarity and visual hierarchy.
Accessibility Considerations
- Keyboard navigation support with focus-visible states for all interactive elements
- ARIA labels on checkboxes to announce state changes to screen readers
- Sufficient color contrast ratios meeting WCAG AA standards
- Semantic HTML structure with proper heading hierarchy
- Visual feedback that doesn’t rely solely on color
Common Pitfalls to Avoid
Avoid using inline styles for state management as they override CSS classes and make debugging difficult. Don’t forget to remove event listeners if dynamically adding/removing columns to prevent memory leaks.
