How do I change the properties of a textarea depending on whether it is being typed into

Question

So I have a website, and I have a text area. The background is white and the text is black. How do I make the background color and color change when it is being typed into?

Please share a code snippet of what you have already done. – MrMaavin Oct 25 '18 at 11:40 — MrMaavin, Oct 25 '18 at 11:40

Simply use :focus pseudo code

textarea:focus {
  background: red;
  color: white;
}

<textarea></textarea>

<textarea rows="4" cols="50" id= "textId">
    My text
</textarea>

<div id="colorChange">My DIV</div>

<script type="text/javascript">
    var textAr = document.getElementById("textId");
    var colorDiv = document.getElementById("colorChange");

    function changeColor(){
        colorDiv.style.color = "blue";
    }

    textAr.addEventListener('keyup',changeColor);
</script>
