How to set "z-index" of canvas elements?

To set the z-index of a canvas element, you can use the CSS property "z-index".

1. First, make sure the canvas element has a unique ID or class attribute so you can target it specifically in your CSS. For example, if your canvas element has an ID of "myCanvas", you can target it like this:

1
2
3

#myCanvas {
  z-index: 2;
}

1. In the above code snippet, "z-index: 2;" sets the z-index of the canvas element with the ID "myCanvas" to 2. You can adjust the value as needed to position the canvas element behind or in front of other elements on the page.
2. Make sure the canvas element is positioned either "absolute", "relative", or "fixed" in order for the z-index property to take effect. For example:

1
2
3
4

#myCanvas {
  position: absolute;
  z-index: 2;
}

With these steps, you can set the z-index of a canvas element to control its stacking order on the page.
