HTML Canvas

Subject: html

🎨 HTML <canvas> Element

The <canvas> element in HTML defines a drawable area where graphics can be rendered using JavaScript. It allows you to draw shapes, images, text, and animations directly onto the web page.

Canvas is pixel-based and ideal for:

  • 📊 Real-time visualizations and graphs
  • 🎮 Web-based games
  • 🧩 Interactive animations and simulations

🔧 Syntax

🚀 Try it in Compiler
  • Always include fallback text for browsers that do not support canvas.
  • You control the canvas entirely through JavaScript.

🧰 Use Cases for Canvas

  • 📈 Drawing real-time charts and graphs
  • 🎮 Creating game engines and visual logic
  • ✨ Building custom animations and particle effects
  • 🖼️ Image processing or editing tools

📌 Key Takeaway

  • The <canvas> element provides a high-performance, low-level drawing API.
  • It requires JavaScript for all interactions.
  • Best for graphics-intensive tasks like animations, visualizations, and games.
  • Not semantic — use it when interactive rendering is needed, not for layout or content structure.
