PHP HTML, apply class to html button and not to PHP linked text

buttons

I have this code i use for my website:

<?php if ($slide1 != null ) : ?><li><img src="<?php echo $this->baseurl ?>

/<?
php echo htmlspecialchars($slide1); ?>" /><p class="caption">
<a href="/algemene-informatie"><?php echo ($slidedesc1); ?>Meer info</a></p></li>

The code isn't seperated as in the example. For some reason I doesn't display otherwise in this editor

Right now the entire thing is displayed as a button with the class "caption". I only want class "caption" to be aplied on "Meer info" and not to "$slidedesc1". How would I do that? Do I change the position of class?
