Click button under canvas in HTML
<p>I have a button in html.</p>

<p>Button is partially covered by canvas (with transparent background) and I can't click it in area covered by canvas.</p>

<p><a href="https://i.stack.imgur.com/kEz67.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/kEz67.png" alt="enter image description here"></a></p>

<p>It is very complicated form rich in graphic and moving these things will require a lot of work.</p>

<p>Is is possible to make canvas "invisible" for mouse click?</p>
