Using defuz's method also works in jsFiddle, but not on my site grr. <a href="http://jsfiddle.net/SqzL5/1/" rel="nofollow">http://jsfiddle.net/SqzL5/1/</a></p> <p><em><strong></em>*</strong><em>Edit 11:17GMT 26/06/2012</em><strong><em>*</em>*</strong></p> <p>Right I gave up on this method as the code seemed to only be getting 1 paragraph value. Anyway I did this instead.</p> <pre><code> // Read more after first paragraph if($('.read-bio').length&gt;0){ //has to be in an each to get different values of varying paragraph lengths $('.actor-bio').each(function(index, item){ $('p:not(:first)', item).hide(); }); $('.read-bio').click(function(){ //If class has class 'clicked' animate to first p height + h3 height if($(this).hasClass('clicked')){ $('.actor-bio p:not(:first)', $(this).closest('.actor-bio-wrapper')).animate({height: 'toggle'}); $(this).html('&amp;raquo; &lt;strong&gt;Read&lt;/strong&gt; More').removeClass('clicked'); } //If no 'clicked' class, animate the height to the original height of the text else{ $('.actor-bio p:not(:first)', $(this).closest('.actor-bio-wrapper')).animate({height: 'toggle'}); $(this).html('&amp;raquo; &lt;strong&gt;Read&lt;/strong&gt; Less').addClass('clicked'); } //stops the stupid # appearing the address bar return false; }); } </code></pre>
