I want to open login /registration dialogs from simple links on the navigation menu. but jquery adds ui-button class to those links and turns then into ugly buttons. How do I prevent this behaviour on : http://www.kullabs.com/
Just don't attach the button-class to them? If they turn into ui-button, that's because you've assigned the as such.
I didnt add those ui-button ui-widget ... classes to those link. Only class I have on the code is 'open-login-form'. Jquery seems to add those button classes to all the links that open a dialog. The 'register' link I added on the login form dialog has been changed as well.
