The canvas is an HTML non-empty element that is used to draw graphics on web pages. The HTML <canvas> gives you an easy and powerful way to draw graphics using JavaScript.<\/p>\n\n\n\n

HTML Canvas Example<\/h3>\n\n\n\n
<canvas id="myCanvas" width="200" height="200"><\/canvas><\/pre>\n\n\n\n
The width and height attribute is necessary to define the size of the canvas.<\/p>\n\n\n\n
The <canvas> element must have an id attribute so it can be referred to by JavaScript.<\/p>\n\n\n\n
By default, the <canvas> element has no border and no content we can add a border and other styles using CSS.<\/p>\n\n\n\n
How to draw the canvas With JavaScript.<\/h3>\n\n\n\n
Note:-<\/strong> The <canvas> element is only a container for graphics. You must use a script to actually draw the graphics.<\/p>\n\n\n\n
Step 1: Define the canvas by using <canvas> element.<\/p>\n\n\n\n
<canvas id="myCanvas" width="200" height="200" style="border:solid"><\/canvas><\/pre>\n\n\n\n
Step 2: Find the Canvas Element by using the HTML DOM method getElementById():<\/p>\n\n\n\n
var canvas = document.getElementById("myCanvas");<\/pre>\n\n\n\n
Step 3: Create a Drawing Object<\/p>\n\n\n\n
The getContext() is a predefined HTML object, with properties and methods for drawing:<\/p>\n\n\n\n
var obj = canvas.getContext("2d");<\/pre>\n\n\n\n
Step 4: Set the fill style of the drawing object.<\/p>\n\n\n\n
In my example we fill the style of the drawing object to the color blue:<\/p>\n\n\n\n
obj.fillStyle = "blue";<\/pre>\n\n\n\n
The fillStyle property can be a CSS color, a gradient, or a pattern. The default fillStyle is black.<\/p>\n\n\n\n
Overall code:<\/h3>\n\n\n\n
<!DOCTYPE html>\n<head>\n    <title>HTML Camvas<\/title>\n<\/head>\n<body>\n    <canvas id="myCanvas" width="200" height="200" style="border: solid;"><\/canvas>\n    <script>\n        var canvas = document.getElementById("myCanvas");\n        var obj = canvas.getContext("2d");\n        obj.fillStyle = "blue";\n        obj.fillRect(0,0,200,200);\n    <\/script>\n<\/body>\n<\/html><\/pre>\n\n\n\n
In the above code, we used the fillRect(x, y, width, height) method to draw a rectangle, filled with the fill style, on the canvas.<\/p>\n\n\n\n
-:Output:-<\/p>\n\n\n
