<h1>Button with div practice</h1>

<canvas id = "d1">



<p>CSS exposes the graphical properties of each object and heading. The structure here resembles a class, where {} specifies useful knowledge.<br>
When using CSS, try to rely on the extended list of parameters. I recommend W3Schools for a detailed look at function arguments.<br>
