HTML Canvas Drawing

Draw on the Canvas With JavaScript

All drawing on the HTML canvas must be done with JavaScript:


var canvas = document.getElementById("myCanvas");
var ctx = canvas.getContext("2d");
ctx.fillStyle = "#fcdda4";

Step 1: Find the Canvas Element

First of all, you must find the <canvas> element.

This is done by using the HTML DOM method getElementById():

var canvas = document.getElementById("myCanvas");

Step 2: Create a Drawing Object

Secondly, you need a drawing object for the canvas.

The getContext() is a built-in HTML object, with properties and methods for drawing:

var ctx = canvas.getContext("2d");

Step 3: Draw on the Canvas

Finally, you can draw on the canvas.

Set the fill style of the drawing object to the color red:

ctx.fillStyle = "#fcdda4";

The fillStyle property can be a CSS color, a gradient, or a pattern. The default fillStyle is black.

The fillRect(x,y,width,height) method draws a rectangle, filled with the fill style, on the canvas:
