## HTML5 Canvas
|
|
|
|
Canvas is a technology introduced in HTML5 which can be accessed by the `<canvas>` tag. It allows graphics to be drawn via JavaScript, and is a powerful tool for interactivity on all modern web browsers. Learn how to draw shapes, manipulate photos, build games, and animate virtually anything following the links below!

|
## Usage
|
|
|
|
```html
|
|
<!DOCTYPE html>
|
|
<html>
|
|
<body>
|
|
<canvas id="myCanvas" width="200" height="100" style="border:1px solid #000111;"></canvas>
|
|
</body>
|
|
</html>
|
|
```
|
|
|
|
1. In the above example, the `"id=myCanvas"` attribute is referred by JavaScript.
|
|
2. The `"width"` & `"height"` attributes are necessary to define the size of the canvas.
|
|
3. By default, `<canvas>` element has no border & no content. So, to add a border we use the `"style"` attribute.
|
|
4. We can have multiple `<canvas>` elements on one HTML page.
