The HTML5 Projects series combines HTML5, CSS3, and recent javascript API technologies to enhance your web projects with interactivity and multimedia. This installment shows how to create a basic to-do list widget with an editable field so users can enter their tasks and delete them as they are completed, and a more advanced version with all the bells and whistles, including a drag-and-drop interface that allows for quick and easy sorting. Author Joseph Lowery covers HTML5 technologies such as web databases, content editing in the browser, and CSS transitions and transforms.
