 Moodle 2.7 has two core themes. The responsive Bootstrap-based theme clean is now the default and other standard themes have been removed. If you used one of the other themes, make sure you reinstall it from the plugins directory before you run your upgrade. There's a new theme, More, which can be customized from within Moodle, making it easier for administrators who don't have access to theme files on the server or who don't have the knowledge to develop their own themes. So if we go to Appearance, Themes, Theme Selector and change the theme from the default theme Clean to the new theme More, we can then see how to modify the More Settings page to configure the theme for our own purposes. We can, for instance, choose our own text color or link color, and then we have the option either of selecting a background color for our theme or, as I'm doing here, bringing in our own created background image. And if we add a background image, there are then options to choose how this image is repeated and its position. Other features include choosing the main content background color and secondary background color for blocks, for example. And if our organization has a logo, again, we can bring this in directly on this page. The More theme also allows us to add custom CSS and to add text in the footer. So if we save the changes and go to the front page of our Moodle, we see that using More enables that administrator quickly to create a customized theme.
