Why is the 'title' attribute legally required on iframes for WCAG compliance?

Screen readers announce iframes to users. Without a descriptive 'title' attribute (e.g. title="Interactive Checkout Form"), visually impaired users have no idea what the embedded content represents.

What is Clickjacking and how does 'Content-Security-Policy: frame-ancestors' prevent it?

Clickjacking tricks users into clicking invisible embedded buttons (like 'Confirm Payment'). The 'frame-ancestors' CSP directive instructs browsers never to render the site inside an unauthorized third-party iframe.

Can an iframe access the JavaScript variables and DOM of its parent window?

Only if both the parent page and iframe share the exact same protocol, domain, and port (Same-Origin Policy). If origins differ, direct DOM access is blocked by browser security.
