need help color changeing shape isnt loading did i make an infanat loop?

im suposed to make one of those circles or squares that randomly change color but all its doing is constantly reloading i tryed changeing 'px' to ('px') but it only works with '10px' or '20px'and still wont show.

function showPattern(){
    const colorArray= ['red', 'orange', 'yellow', 'green', 'blue', 'indigo', 'violet'];
    let topPosition = 25;
    let leftPosition = 25;
    let width = 500;
    let height = 500;

    while(width > 50){
        const randomColorIdx = Math.floor(Math.random() * colorArray.length);
        const newDiv = document.createElement("div");
        newDiv.style.top = topPosition + 'px';
        newDiv.style.left = leftPosition + 'px';
        newDiv.style.width = width +'px';
        newDiv.style.height = height + 'px';
        newDiv.style.background = colorsArr[randomColorIdx];

        document.body.appendChild(newDiv);
        topPosition += 10;
        leftPosition += 10;
        width -= 20;
        height -= 20;
    }
}
