How Can I Achieve Dynamic Text Scaling Based on Browser Width?

Dynamic Text Scaling with Browser Width

Achieving dynamic text scaling based on browser width is indeed possible. Here's how:

Set your document's body font size using JavaScript upon window resizing. This can be achieved using the following jQuery code:

<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>

By setting the font size of the body element in percentage, you create a "universal text zoom" effect, scaling any text set in ems. If desired, you can also target specific elements by setting the percentage font-size on a enclosing div.
