you can customize SharePoint sites

We will continue with the same example of our blank site which we discussed previously. On the left hand side corner, you will see a site actions menu. Click on the site action menu and click on the site settings menu link. Once you click on the link, you will be popped with different settings by which you can do customization. We will not discuss right now what every setting is, but in later sections, we will understand some important settings by which we can achieve customization.
To increase your confidence, you can play around with the ‘Look and feel’ settings. But this will be the landing page when we want to implement customization in SharePoint.
