Increase/Decrease Font Size Script - How Add Default Text Size Function?
<p>Does anybody know how to modify the below script so that, in addition to the two current functions (changeFontSize( id, true); //Increases the font size - changeFontSize( id ); // Decreases size), I can add a third function whereby the font size will be reset to a default setting?</p>

<p>Thank you, Chris</p>

<p>SCRIPT</p>

<p>function changeFontSize( objId, doIncreaseSize ) {
//Define your variables before use, or they will become global.
    var currentSize = 0, 
     obj = document.getElementById( objId ), 
     newVal = 0, 
     limitMax = 10, 
     limitMin = 0.5, 
     unit = 0.1; </p>

<pre><code>if( !obj ){
 return false; //Avoids errors if obj isn't found.
}
currentSize = parseFloat( obj.style.fontSize );
if( doIncreaseSize ){
 unit = -unit; // unit becomes negative. This turns subtractions into addition.
}
newVal = currentSize - unit;
if( limitMax &gt;= newVal &amp;&amp; limitMin &lt;= newVal ){
 obj.style.fontSize = newVal + "em";
}
</code></pre>

<p>};</p>
