HTML and CSS Reference
Figure 1.17. The Super HTML5 Editor you'll build in chapter 3 will allow you to perform file operations such as
creating a new blank file and importing an existing file either by selecting it or dragging it into the application.
It'll store these files in a sandboxed local filesystem, from which you can view, edit, and delete the files or export
them to your computer by dragging them out of the application.
