* transition-property: Specifies the CSS property to which the transition is applied (font-size in this case).

#delay {
font-size: 14px;
transition-property: font-size;
transition-duration: 4s;
transition-delay: 2s;

問題 #34
A web developer need to ensure that a message appears if the user's browser does not support the audio files on a web page.
How should this designer code the audio element?

答案：A

解題說明：
To ensure that a message appears if the user's browser does not support the audio files on a web page, the developer should use the <audio> element correctly. The <audio> element supports fallback content, which is displayed if the browser does not support the specified audio formats.
* Correct Usage:
* Fallback Content: Place the message as fallback content inside the <audio> element. Browsers that do not support the audio format will display this message.
* Example:
<audio>
<source src="audio/song.mp3" type="audio/mpeg" />
No mpeg support.
</audio>
* Explanation of Options:
* Option A: Incorrect. The alt attribute is not valid for the <source> element.
* Option B: Incorrect. The alt attribute is not valid for the <audio> element.
* Option C: Incorrect. The alt attribute is used incorrectly in the <audio> element.
* Option D: Correct. The message "No mpeg support." is placed correctly as fallback content inside the <audio> element.
* References:
* W3C HTML5 Specification - The audio element
* MDN Web Docs - <audio>
Using the fallback content inside the <audio> element ensures that users with unsupported browsers receive a meaningful message, improving the overall user experience.
