Dynamic Text Size Scaling Based on Browser Width

Problem:

In the context of a project, the text size remains static and needs to be dynamically adjusted to approximately 90% of the browser window's width, with corresponding scaling of the vertical text size.

Answer:

Scaling Body Font Size Using JavaScript:

Implement a JavaScript function that sets the body font size based on the browser window's width.

<code class="javascript">$(document).ready(function() {
  var $body = $('body');

  var setBodyScale = function() {
    var scaleSource = $body.width(),
      scaleFactor = 0.35,
      maxScale = 600,
      minScale = 30;

    var fontSize = scaleSource * scaleFactor;

    if (fontSize > maxScale) fontSize = maxScale;
    if (fontSize < minScale) fontSize = minScale;

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

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

  // Fire it when the page first loads:
  setBodyScale();
});</code>

Explanation:

This script adjusts the font size of the entire body element based on the browser window's width. The scaling factor and minimum and maximum font size values can be customized as desired.

Result:

This method ensures that text elements, set in em units, dynamically scale to approximately 90% of the browser's width and adjust their vertical size accordingly.
