Canvas Fixed Html

Welcome to another intriguing post, where we will explore the realm of HTML5, with a specific emphasis on the Canvas element and its successful incorporation of a fixed position within your HTML structure.

What is HTML5 Canvas?

The Canvas element is one of the versatile components offered by HTML5. This powerful feature allows for dynamic, scriptable rendering of 2D shapes and images. It is a container for graphics, where we can draw graphics via JavaScript, with the power to create and manipulate visual content on the fly.

Fixing the Position of the Canvas

Now, let’s dive into the heart of this blog post: fixing the position of our Canvas. There are scenarios where you want your Canvas to maintain a fixed position, irrespective of the scrolling on the page. Fortunately, CSS gives us the power to do this with the style property position: fixed.

Check out the code snippet below on how to implement this:

  canvas {
    position: fixed;
    top: 0px;
    left: 0px;

<canvas id="myCanvas" width="500" height="500"></canvas> 

In the above code, we’re positioning the canvas in a way that it sticks to the top-left corner of the page. The position: fixed property makes sure the canvas remains in the same place even when the page is scrolled.

Adding Content into the Canvas

Now that we have a fixed canvas, let’s add some content to it. We will draw a simple rectangle using JavaScript. Here’s how you can do it:

  let canvas = document.getElementById('myCanvas');
  let ctx = canvas.getContext('2d');

  ctx.fillStyle = 'red';
  ctx.fillRect(20, 20, 150, 100);

In the JavaScript code above, we’re first getting a reference to our canvas, then defining a 2D drawing context. We set the fill color to red, then create a rectangle with the fillRect() method.


The HTML5 Canvas element opens up a world of possibilities for web developers, and learning to fix its position makes it even more powerful, providing a consistent user interface regardless of page scrolling. It’s just one of the ways you can enhance your pages with HTML5 and CSS. Happy coding!
