HTML canvas fillRect() Method

The fillRect() method of the HTML canvas is used to create a filled rectangle on the web page. The default color is black. The <canvas> element allows you to draw graphics on a web page using JavaScript. Every canvas has two elements that describes the height and width of the canvas i.e. height and width respectively.

Following is the syntax −



  • p: The x-coordinate of the upper-left corner of the rectangle
  • q: The y-coordinate of the upper-left corner of the rectangle
  • width: Width of the rectangle
  • height: Height of the rectangle
