    Is it possible to use select() on a group of radiobuttons to get the selected value? And perhaps execute some code based on the one that was clicked?

    @ 10:38 I'm confused as to why you had to make paragraph a global variable for the changeBackground function to work, but the button variable was made inside of setup and canvasBg() still worked… Why does var button not have to be global??

    is it possible to make a random color in a class? like :

    var c = select('#hello');
    c.style('background-color', 'random(255)');

    5:00 for speed it's faster if it's hard coded in html, yes? then next up, referencing a .js file. Finally, a dynamic call to a db for the content, yes? Can p5.js call on a dynamic reference? e.g. createP(makeSomeDBQuery-XYZ)?

    i mean, What´s the reason why you can´t pick a Canvas with an ID?? . I would be so much easyer, Please, please just update p5.js to make this happend. I beg you.

    P5js DOM library rocks! It would be great if, with selectAll("_____") function, I could also possibly do what I can do in native Javascript with querySelectorAll("p.rainbows"): selecting just the paragraphs of the class "rainbows" (not the button).

    Thanks Daniel, I'm addicted to your videos. A total brain fertilizer.
    And a question as well – once I've selected an element, is there a way to check a specific style attribute, such as width?
