What accessibility standard did you base your work on, and which key achievement levels did you use?

In working on accessibility, I relied on the WCAG (Web Content Accessibility Guidelines) standard, which is the most widespread and recognized.

Key levels of achievability in WCAG:

• A (minimum level) — basic requirements, without which the site is considered inaccessible.
• AA (medium level) — recommended level for most sites, includes improvements for a broader range of users.
• AAA (high level) — the strictest level, rarely fully achieved, includes additional recommendations.

In projects, I usually aim for the AA level, ensuring:

• Contrast between text and interface elements.
• Keyboard navigation capability.
• Semantic HTML markup.
• Alternative texts for images.
• Support for screen readers.

This helps make the interface accessible for people with disabilities and improves the overall user experience.
