Web Interface Guidelines

• Icon-only buttons need aria-label
• Form controls need <label> or aria-label
• Interactive elements need keyboard handlers (onKeyDown/onKeyUp)
• <button> for actions, <a>/<Link> for navigation (not <div onClick>)
• Images need alt (or alt="" if decorative)
• Decorative icons need aria-hidden="true"
• Async updates (toasts, validation) need aria-live="polite"
• Use semantic HTML (<button>, <a>, <label>, <table>) before ARIA
• Headings hierarchical <h1>–<h6>; include skip link for main content
• scroll-margin-top on heading anchors
