HTML Canvas implementation guide on Parent Resize - Need Guidance with Event Listeners
I'm wondering if anyone has experience with I'm working on a responsive web application and using an HTML `<canvas>` to render some dynamic graphics... However, I've run into an scenario where the canvas does not resize or update correctly when its parent container changes size. I'm using plain JavaScript and I've set up an event listener for the `resize` event, but it seems like the canvas is not responding as expected. Here's a simplified version of my code: ```html <div id="canvas-container" style="width: 100%; height: 400px;"> <canvas id="myCanvas" width="800" height="400"></canvas> </div> ``` ```javascript const canvas = document.getElementById('myCanvas'); const context = canvas.getContext('2d'); function draw() { context.clearRect(0, 0, canvas.width, canvas.height); // Drawing some shapes context.fillStyle = 'blue'; context.fillRect(10, 10, 50, 50); } draw(); window.addEventListener('resize', () => { const container = document.getElementById('canvas-container'); canvas.width = container.clientWidth; canvas.height = container.clientHeight; draw(); }); ``` The question is that when I resize the browser window, the canvas does receive the new width and height but the graphics don't scale properly, and I can see a flickering effect. I've tried logging the new dimensions, and they appear correct, but the drawn shapes don't adjust. What am I missing here? I've also considered the potential impact of CSS styles affecting the canvas, but I made sure there are no conflicting styles. I’ve checked for common pitfalls with the `resize` event and tried debouncing it as well, but the question continues. Any suggestions on how to ensure that my canvas graphics update correctly upon resizing the parent element? I'm working with Javascript in a Docker container on CentOS. Am I missing something obvious?
