How to Dynamically Scale Text Element Sizes on Window Resize

Scaling Text with Window Resizing

In the world of web design, responsiveness often extends beyond images. When users resize their browser windows, it's desirable for not only images but also text elements to adjust their size accordingly.

One common approach to this challenge is through CSS. Images can be easily set to maintain their aspect ratio and scale with the window using techniques like background-size: contain. However, replicating this functionality for text can prove more elusive.

To achieve dynamic scaling of text, consider implementing a JavaScript solution using jQuery. By setting a base font size for the body element and expressing all other font sizes as percentages of the base, you can dynamically adjust the base font size on window resize. This ripple effect will automatically update all text sizes on the page.

Here's an example jQuery script that accomplishes this:

<code class="javascript">$(function() {
    $(window).bind('resize', function() {
        resizeMe();
    }).trigger('resize');
});

function resizeMe() {
    //Standard height, for which the body font size is correct
    var preferredHeight = 768;
    //Base font size for the page
    var fontsize = 18;

    var displayHeight = $(window).height();
    var percentage = displayHeight / preferredHeight;
    var newFontSize = Math.floor(fontsize * percentage) - 1;
    $("body").css("font-size", newFontSize);
}</code>

With this script in place, your web page's text elements will seamlessly adjust their size as users resize their browser windows.
