1. Introduction to HTML5 Multimedia Graphics

HTML5 multimedia graphics open the door to visually captivating and interactive web experiences.

2. Harnessing Scalable Vector Graphics (SVG)

Learn the fundamentals of SVG, a markup language for creating two-dimensional vector graphics.

Basic Shapes: <rect>, <circle>, <ellipse>, <line>, <polyline>

 
<svg width="100" height="100">
    <rect x="10" y="10" width="80" height="80" fill="blue" />
    <circle cx="50" cy="50" r="40" fill="red" />
    <ellipse cx="50" cy="50" rx="30" ry="20" fill="green" />
    <line x1="10" y1="90" x2="90" y2="10" stroke="black" />
    <polyline points="10,10 50,90 90,10" fill="none" stroke="orange" />
</svg>

Text: <text> and <tspan>

 
<svg width="200" height="100"> <text x="10" y="30">Hello, <tspan fill="blue">World!</tspan></text> </svg>

Transformations and Styling

 
<svg width="100" height="100"> <rect x="10" y="10" width="80" height="80" fill="blue" transform="rotate(45 50 50)" /> </svg>

3. Unleashing the Power of HTML5 Canvas

Explore the dynamic capabilities of the HTML5 Canvas element for drawing graphics on the fly.

Drawing Shapes and Paths

 
<canvas id="myCanvas" width="200" height="100"></canvas>
<script>
    const canvas = document.getElementById("myCanvas");
    const ctx = canvas.getContext("2d"); ctx.fillStyle = "blue";
    ctx.fillRect(10, 10, 80, 80); 
</script>

Adding Interactivity

 
<canvas id="interactiveCanvas" width="200" height="100"></canvas>
<script>
    const canvas = document.getElementById("interactiveCanvas");
    const ctx = canvas.getContext("2d");
    canvas.addEventListener("mousemove", (event) => {
        ctx.clearRect(0, 0, canvas.width, canvas.height);
        ctx.fillStyle = "red";
        ctx.fillRect(event.clientX - 10, event.clientY - 10, 20, 20);
    }); 
</script>

Applying Transformations

 
<canvas id="transformCanvas" width="200" height="100"></canvas>
<script>
    const canvas = document.getElementById("transformCanvas");
    const ctx = canvas.getContext("2d"); ctx.fillStyle = "green";
    ctx.fillRect(10, 10, 50, 50); ctx.setTransform(1, -0.3, 0, 1, 0, 0);
    ctx.fillStyle = "blue"; ctx.fillRect(10, 10, 50, 50); 
</script>

4. Creating a Simple Animation with SVG and Canvas

Combine SVG and Canvas to create a basic animation.

    <rect x="10" y="10" width="80" height="80" fill="blue" />
    <circle cx="50" cy="50" r="40" fill="red" />
    <rect x="100" y="10" width="80" height="80" fill="green" />
</svg> 
<canvas id="combinedCanvas" width="200" height="100"></canvas>
<script>
    const canvas = document.getElementById("combinedCanvas");
    const ctx = canvas.getContext("2d");
    ctx.fillStyle = "orange"; ctx.fillRect(10, 10, 80, 80); 
</script>

7. Styling Graphics with CSS
