Did you finish your work?

When i run this code i get an error saying its reading null from .style which dosent make any sense to me because im assigning it an value not reading it.

  document.body.style.background = "rgb(29, 33, 240);";
}

setInterval(colorChange, 1);

    document.body.style.backgroundColor = "red";

    just use this line then you can see your element color has changed….

    You need to remove the semicolon after the rgb for it to work, as you’re assigning a value, not writing a complete CSS statement. Also, your setInterval isn’t really doing anything (it just perpetually sets the background color to a semi-blue color every millisecond).

    function colorChange() {
  document.body.style.background = "rgb(29, 33, 240)";
}

colorChange();
