Button not working with wordpress 4.0

At my website the button is not working either. (https://www.hotelsandproperties.com) Someone told me to add #callnowbutton:active {initial;} to the CSS. It did not work, but maybe it works for your site.

PS, I have another website: http://www.garagevanewijk.nl/ which uses WP 4.1, there it works fine.
