How Can I Dynamically Resize Font Size to Fit Text Within a Div?

Dynamic Font Sizing Within a Div

To seamlessly adapt text content within a div to fit its dimensions, consider the following solution:

jQuery Implementation:

This JavaScript code, implemented using jQuery, adjusts the font size iteratively until the text fits within the div:

$(function() {
    while( $('#fitin div').height() > $('#fitin').height() ) {
        $('#fitin div').css('font-size', (parseInt($('#fitin div').css('font-size')) - 1) + "px" );
    }
});

HTML Structure:

Define a div with the ID "fitin" and nest another div within it containing the text:

<div>
<p><strong>CSS Styling:</strong></p>
<p>To constrain the div size and hide overflowing content, add this CSS:</p>
<pre class="brush:php;toolbar:false">#fitin {
    width: 300px;
    height: 100px;
    border: 1px solid black;
    overflow: hidden;
    font-size: 1em;
}

Example Usage:

Initialize the JavaScript code within the $(function() {...}) block to automatically adjust the font size when the page loads.

This solution ensures that text content can gracefully fit within a div, regardless of its dimensions, providing a flexible and user-friendly experience for dynamic content.
