With the basic skeleton of the web journal in place, let's change the look of the pages to reflect a preset theme. By default, Aperture applied the Stock theme, which uses a white background, but let's use something more dramatic.
1.
Click the Site Theme button in the upper left corner of the Webpage Editor. The Choose Web Theme window appears, offering a selection of preset templates for creating standard HTML webpages.
2.
Select the Stock Black theme and then click the Choose button to apply the new theme and return to the Webpage Editor. Aperture returns to page 1 of the site when you apply a new theme.
You have now created the structure of your web journal and given it a theme, or style. Now, you need to customize the text.
