HTML and CSS Reference
down a bit in the window shown in Figure 6-6, you will find a Background input field. As you learned
in Chapter 2, “Making sense of HTML5,” HTML colors are expressed in the format #rrggbb where rr,
gg, and bb indicate the hexadecimal values of the red, green, and blue color components. To get a
nice light blue color, enter #2eccfa .
Adding a splash screen
Every Windows Store application should have a splash screen. A splash screen is an image that
displays right after the user launches the application and remains visible until the application is ready
for interaction. Any Visual Studio project template offers a free splash screen that developers have
only to edit with a graphical tool such as Paint.NET. Figure 6-9 shows a reworked splash screen for the
FIGURE 6-9 The splash screen of the TodoList sample application.
There are a few guidelines to keep in mind that apply to splash screens. To begin with, the only
purpose of a splash screen is giving users immediate feedback about the application. Windows 8
guidelines recommend that you provide extremely simple images that basically consist of the
application's logo placed at the center of the logo surface—620 x 300 pixels.
Ideally, the logo has a transparent background and uses colors that blend well with the selected
background color for the splash screen. You can set the selected background color for the splash
screen in the manifest editor. You should also avoid showing advertisements and versioning
information in the splash screen.
Getting serious with the TodoList application
The next step in the process of building the TodoList application consists of adding an interactive
form for the user to enter information about and keep track of a task. In doing so, you'll get familiar
with some of the input controls available in Windows 8, as well as some of the HTML5 elements you
encountered in Chapter 2.
