A.

600.jpg, because sizes is evaluated independently of pixel density.

B.

600.jpg, because the image occupies 600 CSS pixels.

1200.jpg, because the 600-pixel slot is rendered at 2x density.

SVG Graphics Hard

A.

nonzero fills the inner region, while evenodd treats it as a hole.

B.

nonzero creates a hole, while evenodd fills the inner region.

C.

Both rules create a hole because the subpaths are concentric.

D.

Both rules fill the region because subpath direction is always ignored.

56 $A modern browser supports the <video> element, but none of the supplied <source> formats can be decoded. What happens to a paragraph placed as fallback content inside <video> ?$

Multimedia Elements: Audio, Video and Iframes Hard

A.

The paragraph remains undisplayed because it is fallback for browsers lacking <video> support.

Multimedia Elements: Audio, Video and Iframes Hard

A.

Treat result as a promise and handle rejection, such as a NotAllowedError .

B.

Treat result as a boolean and retry immediately whenever it equals false .

C.

Assume playback starts because calling play() overrides declarative autoplay rules.

D.

Wait for loadedmetadata, after which play() cannot be blocked by policy.

58 $A same-origin page is embedded using <iframe sandbox="allow-scripts" src="/tool.html"></iframe> . Which statement best describes the embedded page?$

Multimedia Elements: Audio, Video and Iframes Hard

A.

Its scripts may run, and it retains the parent origin because the URL is same-origin.

B.

Its scripts may run, but it receives an opaque origin for same-origin security checks.

C.

Its scripts are blocked because allow-same-origin is required before allow-scripts works.

D.

Its scripts may run only after the parent grants access through postMessage() .

59 $Several URLs expose substantially identical content and each duplicate contains <link rel="canonical" href="https://example.com/preferred"> . What does the canonical link do?$

It guarantees that only the preferred URL can appear in every search engine's results.

It provides a consolidation hint to search engines but does not redirect users or guarantee selection.

60 $A developer writes <button type="button"><a href="/checkout">Checkout</a></button> to obtain button styling and navigation. What is the best correction?$

HTML Best Practices Hard

A.

Keep both elements but add role="link" to the outer button for clearer semantics.
