title: How to make fontAwesome Icon at the end of the input field clickable too
body: <p>I have an input field with jQuery date picker. So when you click on the input field it will show the calendar. I have also inserted a calendar Font Awesome icon in the :after. How do I make that part clickable too and launch the jQuery calendar? I can't make the background of the input field transparent because I need it to be white. </p>
