Hello, When validating the site http://feestdagen2013.nl I get the following error: Error Line 17, Column 5889: The allowtransparency attribute on the iframe element is obsolete. Use CSS instead. When looking at the issue I see this is generated from the Twitter button with the following code: <a href="http://twitter.com/share" class="twitter-share-button" data-url=" http://feestdagen2013.nl" data-text="Alle feestdagen in 2013!" data-count="horizontal">Tweet</a><script type="text/javascript" src=" http://platform.twitter.com/widgets.js"></script> This is the code from a default Twitter share button. Is there anyway I can resolve the issue within the code? Any comment would be appreciated. SamReceived on Sunday, 12 August 2012 16:24:38 UTC
