HTML5 <canvas> Not Rendering on Mobile Safari with Touch Events
I'm learning this framework and I'm having trouble with I'm attempting to set up I'm trying to figure out I'm working with an scenario with an HTML5 `<canvas>` element that fails to render correctly on Mobile Safari (iOS 15.4). The canvas appears blank, and I'm not seeing any errors in the console. I have a simple drawing application that works perfectly on desktop browsers but doesn't behave the same way on mobile devices. Here is the relevant snippet of my code: ```html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Canvas Test</title> <style> canvas { border: 1px solid black; } </style> </head> <body> <canvas id="myCanvas" width="400" height="400"></canvas> <script> const canvas = document.getElementById('myCanvas'); const ctx = canvas.getContext('2d'); let drawing = false; canvas.addEventListener('touchstart', (e) => { drawing = true; ctx.beginPath(); ctx.moveTo(e.touches[0].clientX - canvas.offsetLeft, e.touches[0].clientY - canvas.offsetTop); }); canvas.addEventListener('touchmove', (e) => { if (drawing) { ctx.lineTo(e.touches[0].clientX - canvas.offsetLeft, e.touches[0].clientY - canvas.offsetTop); ctx.stroke(); } }); canvas.addEventListener('touchend', () => { drawing = false; }); </script> </body> </html> ``` I've confirmed that touch events are firing by adding some console logs, but none of my drawings are visible on the canvas. I suspect it might be related to the fact that the touch events behave differently on mobile compared to mouse events. I've also tried setting `touch-action: none;` in CSS, but that didn't resolve the scenario. Any insights on how to make the canvas rendering work on Mobile Safari would be greatly appreciated! This is my first time working with Html 3.9. Thanks, I really appreciate it! I'm using Html stable in this project. This is part of a larger desktop app I'm building. Cheers for any assistance! I'd love to hear your thoughts on this. I'm working on a CLI tool that needs to handle this. I'd be grateful for any help.
