Why does the whole page refresh when I use jQuery to increase or decrease the font size?
<p>I have a HTML page where I want one button to increase the font size and the same button to decrease the font size when clicked.</p>

<p>I am using jQuery like so:</p>

<pre><code>$("p").css("font-size","20")
</code></pre>

<p>However, when I do that the font size increases for maybe 2 seconds and then goes back to normal. It appears that the page is refreshing after I click the button... Why is that?</p>
