Practice

1. What is the main purpose of the <video> tag in HTML?

easy

A. To embed videos directly on a webpage

B. To create audio playlists

C. To add images to a webpage

D. To style text content

Solution

1. Step 1: Understand the role of the <video> tag

   The <video> tag is designed to embed video content directly into HTML pages.

2. Step 2: Compare with other options

   Options A, B, and C relate to audio, images, and text styling, which are not the purpose of <video>.

3. Final Answer:

   To embed videos directly on a webpage -> Option A

4. Quick Check:

   <video> tag = embed videos [OK]

Hint: Remember: <video> is for videos, not audio or images [OK]

Common Mistakes:

• Confusing <video> with <audio> tag
• Thinking <video> adds images
• Assuming <video> styles text

2. Which of the following is the correct way to add playback controls to a video using the <video> tag?

easy

A. <video src="movie.mp4" play></video>

B. <video src="movie.mp4" playcontrols></video>

C. <video src="movie.mp4" control></video>

D. <video src="movie.mp4" controls></video>

Solution

1. Step 1: Identify the correct attribute for controls

   The correct attribute to add playback controls is controls without any extra letters.

2. Step 2: Check each option's attribute spelling

   <video src="movie.mp4" controls></video> uses controls correctly; others have incorrect or non-existent attributes.

3. Final Answer:

   <video src="movie.mp4" controls></video> -> Option D

4. Quick Check:

   Use controls attribute to add buttons [OK]

Hint: Use exactly 'controls' attribute to show video buttons [OK]

Common Mistakes:

• Misspelling 'controls' as 'control' or 'playcontrols'
• Using non-existent attributes like 'play'
• Forgetting to close the video tag properly

3. What will the following HTML code do when opened in a modern browser?

<video controls>
  <source src="video.webm" type="video/webm">
  <source src="video.mp4" type="video/mp4">
  Your browser does not support the video tag.
</video>

medium

A. Show error message and no video

B. Play video.mp4 only, ignoring video.webm

C. Play video.webm if supported, else video.mp4

D. Play both videos simultaneously

Solution

1. Step 1: Understand multiple <source> tags in <video>

   The browser tries each <source> in order and plays the first supported format.

2. Step 2: Analyze the source order and browser support

   If the browser supports WebM, it plays video.webm; otherwise, it falls back to video.mp4.

3. Final Answer:

   Play video.webm if supported, else video.mp4 -> Option C

4. Quick Check:

   Multiple sources = fallback to supported video [OK]

Hint: Browser picks first supported source in order [OK]

Common Mistakes:

• Assuming both videos play at once
• Thinking only the last source is used
• Ignoring fallback text for unsupported browsers

4. Identify the error in this video tag code:

<video src="movie.mp4" controls>
  <source src="movie.webm" type="video/webm">
</video>

medium

A. The controls attribute is misspelled

B. The src attribute should not be used with <source> tags inside <video>

C. The <source> tag is missing a closing slash

D. The <video> tag cannot have multiple sources

Solution

1. Step 1: Understand usage of src and <source> tags

   When using multiple <source> tags, the src attribute on <video> should be omitted to avoid conflicts.

2. Step 2: Check other options for errors

   controls is spelled correctly, <source> tags do not require closing slashes in HTML5, and multiple sources are allowed.

3. Final Answer:

   The src attribute should not be used with <source> tags inside <video> -> Option B

4. Quick Check:

   Use either src or <source>, not both [OK]

Hint: Don't mix video src attribute with source tags [OK]

Common Mistakes:

• Using src on video with source tags
• Thinking <source> needs closing slash
• Believing controls attribute is misspelled

C. <video src="clip.mp4" autoplay loop controls></video>

D. <video src="clip.mp4" loop controls></video>

Solution

1. Step 1: Identify required attributes for autoplay, loop, and mute

   <video src="clip.mp4" autoplay loop muted></video> has all three attributes and no controls, matching the requirement exactly.

3. Final Answer:

   <video src="clip.mp4" autoplay loop muted></video> -> Option A

4. Quick Check:

   Use autoplay, loop, muted together for silent looping video [OK]

Hint: Combine autoplay, loop, muted attributes for silent looping video [OK]

Common Mistakes:

• Forgetting muted causes autoplay to block
• Adding controls when not needed
• Missing one of the required attributes
