In this exercise you create two themes: Monochrome and DarkGrey. For
each theme, you add the CSS layout, which is applied to the site automatically.
You configure the application to use one of the themes and then switch to the other to see the differences.
1. Add the special App_Themes folder to your website. To do this,
right-click the website in the Solution Explorer and choose Add
Í Add ASP.NET Folder Í Theme. This not only creates the App_Themes folder, but immediately creates a subfolder for the theme called Theme1 by default. Type Monochrome as the new name instead. Your Solution Explorer should now look like
Figure 6-14.
2. From the Styles folder, move the Styles.css file into this new
Monochrome folder. You can either drag it directly into the new
folder or use Ctrl+X to cut the file, click the Monochrome folder,
and press Ctrl+V to paste it again. You can leave the empty Styles folder because it’s used again later.
