HTML, or Hypertext Markup Language, is the primary language for structuring web pages. It collaborates with CSS and JavaScript to define content, appearance, and behavior. HTML comprises elements enclosed in angle brackets, encompassing various webpage components like headings, paragraphs, images, and links. The standard structure includes the , , and elements. HTML facilitates hyperlink creation through the tag, enabling seamless navigation between web pages. HTML5, the latest version, introduces new elements and attributes, enhancing web functionality and accessibility. In essence, HTML serves as the foundation for creating structured, interactive web content, essential for web development and design.

Canvas and SVG elements
About Lesson

Canvas and SVG are two different approaches for creating graphics in HTML.

1. **Canvas:**
– `<canvas>` is an HTML element introduced in HTML5.
– It provides a drawing surface that allows you to create and manipulate graphics using JavaScript.
– Canvas is pixel-based, meaning you directly manipulate individual pixels on the canvas.
– You can draw shapes, lines, text, images, and perform animations using Canvas API methods like `getContext(‘2d’)`.
– Canvas is well-suited for dynamic, interactive graphics and animations, such as games, data visualizations, and drawing applications.

<canvas id=”myCanvas” width=”400″ height=”200″></canvas>
var canvas = document.getElementById(‘myCanvas’);
var ctx = canvas.getContext(‘2d’);
ctx.fillStyle = ‘blue’;
ctx.fillRect(50, 50, 100, 100); // Draw a blue rectangle

2. **SVG (Scalable Vector Graphics):**
– SVG is an XML-based markup language for describing vector graphics.
– It allows you to create graphics that scale seamlessly to any size without losing quality.
– SVG graphics are resolution-independent and can be manipulated with CSS and JavaScript.
– You can create shapes, paths, text, gradients, and complex illustrations using SVG elements and attributes.
– SVG is ideal for static or interactive graphics that require scalability and precision, such as icons, logos, and diagrams.

<svg width=”400″ height=”200″>
<rect x=”50″ y=”50″ width=”100″ height=”100″ fill=”blue”/>

In summary, Canvas is pixel-based and suitable for dynamic graphics, while SVG is vector-based and suitable for scalable, static or interactive graphics. Depending on the requirements of your project, you can choose between Canvas and SVG to create the desired visual effects and functionality.
