1. Adding Images to Your Website with HTML

Images can significantly improve the visual appeal and informativeness of your website. Here’s how you can add images using HTML.

Using the <img> Element

html
<img src="images/mountain.jpg" alt="A beautiful mountain landscape" width="600" height="400">

Responsive Images

To make images responsive, you can use CSS.

  img {
    max-width: 100%;
    height: auto;
  }
</style>

2. HTML Audio and Video: Adding Multimedia to Your Site

Adding Audio

The <audio> element is used to embed audio files.

  Your browser does not support the video element.
</video>

• controls: Adds play, pause, and volume controls.

  <source src="videos/movie.ogg" type="video/ogg">
  Your browser does not support the video element.
</video>

3. HTML Canvas: Creating Dynamic Graphics

The <canvas> element allows you to draw graphics using JavaScript. This can be used for creating dynamic, interactive visuals on your web page.

Basic Canvas Setup

First, create a canvas element in your HTML.

html
<canvas id="myCanvas" width="600" height="400"></canvas>

Drawing on the Canvas

Use JavaScript to draw on the canvas.

html
<script>
  var canvas = document.getElementById("myCanvas");
  var ctx = canvas.getContext("2d");

  // Draw a rectangle
  ctx.fillStyle = "#FF0000";
  ctx.fillRect(20, 20, 150, 100);
</script>

Drawing Shapes and Text

You can draw various shapes and text on the canvas.

html
<script>
  var canvas = document.getElementById("myCanvas");
  var ctx = canvas.getContext("2d");

  // Draw a circle
  ctx.beginPath();
  ctx.arc(200, 150, 50, 0, 2 * Math.PI);
  ctx.stroke();

  // Draw text
  ctx.font = "30px Arial";
  ctx.fillText("Hello Canvas", 10, 50);
</script>

Animations

Create animations by repeatedly drawing and clearing shapes.

html
<script>
  var canvas = document.getElementById("myCanvas");
  var ctx = canvas.getContext("2d");
  var x = 0;

  function draw() {
    ctx.clearRect(0, 0, canvas.width, canvas.height);
    ctx.fillStyle = "#0095DD";
    ctx.fillRect(x, 100, 50, 50);
    x += 2;
    requestAnimationFrame(draw);
  }

  draw();
</script>
