HTML Media

  • This lesson explains how to add and use media elements such as images, audio, and video in HTML webpages using simple examples.

  • HTML media elements transform a boring text webpage into an interactive, visual, engaging experience.

    🌟 Why HTML Media Is Important

    Websites use media everywhere:

     🎵 Music / Podcasts (Spotify, Soundcloud)
     🎬 Videos & Tutorials (YouTube, Udemy)
     🗺️ Maps & Tools (Google Maps embeds)
     📺 External embeds (YouTube, Vimeo, ads)

    👉 Media increases engagement, clarity, and user experience.

  • 🎵  Audio in HTML

    🎧 Basic Audio Player

    <audio controls>

        <source src="song.mp3" type="audio/mpeg">

    </audio>

    🔍 Browser loads audio → shows a music player.

    User can:

    • Play

    • Pause

    • Adjust volume

    • Seek

      🎚️ Audio Attributes

      Attribute Purpose
      controlsShows play/pause UI
      autoplayStarts automatically
      loopRepeats the audio
      mutedStarts muted
      preloadHow much audio to preload

    Using the HTML Audio Tag

    The HTML audio tag is used to add sound to a webpage and allows users to play audio files directly in the browser using built-in controls. 

    <audio controls loop muted> 
	<source src="song.mp3"> 
</audio>

    • 📌 Autoplay usually needs muted (browser rules).

      🎼 Multiple Audio Formats (Compatibility)

    Multiple Audio Formats for Browser Compatibility

    This example shows how to use multiple audio formats in HTML so the audio plays correctly across different browsers. 

    <audio controls> 
	<source src="song.mp3" type="audio/mpeg"> 
	<source src="song.ogg" type="audio/ogg">
	Your browser does not support audio. 
</audio>
    • ✔ Browser picks the first supported format
      ✔ Ensures compatibility across devices

    • 🎬 Video in HTML

      🎥 Basic Video Example

      <video width="400" controls>

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

      </video>

      🔍 How Video Works

      • Browser loads video file

      • Displays built-in video player

      • User controls playback (play/pause/fullscreen)

      AttributeMeaning
      controlsPlay/pause UI
      autoplayAuto play
      loopReplay forever
      mutedRequired for autoplay

      ✨ Background Video (Used in Modern Websites)

    Background Video Section

    This video plays automatically in a loop without sound, creating an engaging background effect for the webpage. 

    <video autoplay muted loop width="100%"> 
    <source src="bg.mp4" type="video/mp4"> 
</video>

    • ✔ Used on homepages
      ✔ Great visual effect
      ✔ Must be muted to autoplay

      🎞️ Multiple Video Formats

    Multiple Video Formats

    This example shows how to use multiple video formats in the video tag to ensure better browser compatibility and smooth video playback. 

    <video controls> 
    <source src="video.mp4" type="video/mp4"> 
    <source src="video.webm" type="video/webm"> 
</video>
    • Ensures browser compatibility.

    • 🌍 4. Iframe (Embedding External Content)

      🧩 Basic Iframe Syntax

      <iframe 

          src="https://www.youtube.com/embed/xyz" 

          width="400" 

          height="250">

      </iframe>

      What is an Iframe?

      An iframe embeds another website inside your page.

      ⭐ Common Uses

       📺 YouTube embeds
       🗺️ Google Maps
       📄 External dashboards
       📦 Ads & widgets

      srcPurpose

      sandboxSecurity restrictions

      🔐 Secure Iframe Example

    Using iframe in HTML

    The iframe tag is used to embed another webpage inside the current page. 

    <iframe src="page.html" sandbox loading="lazy"> </iframe>

    • ✔ Blocks malicious scripts
      ✔ Safer embedding

      Always provide:

      ✔ alt for images
       ✔ captions/subtitles for videos
       ✔ Avoid autoplay audio
       ✔ Provide fallback text

      Example:

    HTML Video Tag Example

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