Now that we’ve configured the basics of our blogging site, let’s now look at how we can customize it even further. To-do that let’s go back to WebMatrix and click on the “Files” node within the left-hand navigation bar of the tool:

This will open a file-system explorer view on the left-hand side of the tool, and allow us to browse the site, and open/edit/add/delete its files. 

Most of the applications within the web gallery support a concept of “themes” and enable developers to tweak/customize the layout, styling and UI of the application.  Above I’ve drilled into BlogEngine.NET’s “themes” folder and opened the Site.Master file to customize the “standard” theme’s master layout.  We could tweak/customize it, hit save, and then run the site again to see our changes applied (note: pressing F12 is the keyboard short-cut to re-run the application).
