如何實現基於瀏覽器寬度的動態文字縮放？

<code class="javascript">$( document ).ready( function() {
    var $body = $('body'); // Cache this for better performance

    var setBodyScale = function() {
        var scaleSource = $body.width(),
            scaleFactor = 0.35,                     
            maxScale = 600,
            minScale = 30; // Adjust these values to your preference.

        var fontSize = scaleSource * scaleFactor; // Multiply the body width by the scale factor.

        if (fontSize > maxScale) fontSize = maxScale;
        if (fontSize < minScale) fontSize = minScale; // Enforce minimum and maximums.

        $('body').css('font-size', fontSize + '%');
    }

    $(window).resize(function(){
        setBodyScale();
    });

    // Initializing when the page first loads.
    setBodyScale();
});</code>
