What, who, where am I?!?
Craig Lotter is a web developer based in Gordon's Bay, South Africa, who seems completely incapable of shaking off that pesky inner child within, the one that forces him to love all things animated or hand drawn.
The Rugged Rock of Craig contains snippets of his life, popular culture and all the important things like anime, manga, games and comic books. The CodeUnit of Craig on the other hand contains the more serious stuff like code snippets and tutorials, while the House of C chronicles his foray into the world of web comics.
For which it never seems he has enough time anyway.

jQuery: How to Locate the Selected Radio Button out of a Group of Radio Buttons
Radio buttons are pretty awesome when you need to ensure that a user has picked ONE of the given options presented to them, and using jQuery, it turns out to be a pretty simple affair to determine and manipulate exactly which radio button is currently selected from the group. Continue reading
jQuery Draggable, Droppable and Sortable User Interface not working in Internet Explorer 9 (IE 9)
I received a bit of a nasty shock when by sheer chance, one of the project managers updated their machines and got Internet Explorer 9 installed in the process, only to instantly come back to me and announce that the drag and drop features on our web project no longer worked – at all.
