p5js stuck into a div on this page.

I am not going to explain how a <div> gets onto a page in a certain position. However, I will show how to position a p5js canvas into a <div>.

1. In your HTML, create an ID. For example, <div ID='idName'>
   It must be an ID, not a class.
2. Now in your p5js code for setup, write this:
   function setup() {
   let cvs = createCanvas(400,400);
   cvs.parent("idName");}
   //end setup
   That puts canvas into the <div> so all you have to do is get the <div> to be where you want it.
3. That's it. Notice that there was no CSS. You will still use a CSS class to position the <div>, but it has nothing to do with making the p5js canvas be inside that div.
