My first post, please forgive me if I'm doing it wrong.

For some reason when switching to the visual editor WordPress will strip out my a tags. "Don't use the visual editor" isn't an option, I'm making a website for clients and I'm trying to make it foolproof. I don't want them to be able to go to the visual editor and accidentally have all the links stripped out.

This is a sample of the code. When switching to visual and back to text, everything is there but the a tags.

<a href="" target="_blank" title="Donate Now">
<div class="donate-now">
<div class="wred">
<h1>Click here to Donate Now</h1>
<div class="wbumpred"> </div>
</div>
</div>
</a>

class="wred" styles a background colour and shape.
class="wbumpred" adds a small graphic element to the bottom of the "wred" element.

Please help!

Thanks,
Sarah
