removing a css style with javascript
<p>I have normal HTML input fields, that have default borders depending on Window/Browser settings.</p>

<p>During form validation I set the border of elements to red. for Example</p>

<pre><code>elem.style.border = "1px solid #ff0000";
</code></pre>

<p>If the user corrects the input, I want to remove the red border, so that the input field contains again the
default border.</p>
