How can I create responsive joystick-layout buttons in HTML?
<p>I'm creating Raspberry Pi WiFi controlled webcam robot. I've created a responsive window for the webcam feed, but I am unable to create the joystick buttons to control my robot.</p>

<p>This is the type of joystick I want to display below the feed:</p>
