How Can I Automatically Adjust Text Size to Fit Within a Div?

Adapting Text Size to Fit a Div

In your situation, you have a background image with a div where you want to display text. However, you'd like the text's font size to automatically adjust to fit within the div. To accomplish this, consider the following solution:

jQuery Implementation:

HTML:

<div>
<p><strong>CSS:</strong></p>
<pre class="brush:php;toolbar:false">#fitin {
    width: 300px;
    height: 100px;
    border: 1px solid black;
    overflow: hidden;
    font-size: 1em;
}

JavaScript:

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

This code iteratively reduces the font size until the text fits snugly within the div.
