D. Answer these questions

1. Discuss the use of src and alt attributes of <img> element.

The <img> element is used to display images in a webpage. Two important attributes of <img> are:

• src (source)

  • This attribute specifies the path or URL of the image to be displayed.

  • Example:

    <img src="flower.jpg" alt="A red rose">
    

• alt (alternative text)

  • This attribute provides descriptive text for the image.

  • 
    

  • Example:

  • <img src="flower.jpg" alt="A red rose in full bloom">
    

Usefulness:

• src ensures the image appears correctly.

• alt improves accessibility and SEO and provides information when images fail to load.

2. Discuss the use of any three attributes of <video> / <audio> elements.

The <video> and <audio> elements are used to embed media in webpages. Important attributes are:

1. controls

   • Displays play, pause, volume, and other controls for users.

   • Example:

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

2. autoplay

   • Starts playing the media automatically when the page loads.

   • Example:

     <audio src="song.mp3" autoplay></audio>
     

3. loop

   • Plays the media repeatedly in a loop.

   • Example:

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

Other attributes: muted (start muted), preload (load media in advance).

    • circle (hollow circle)

    • square (square bullet)
