To access your team site, you use a web browser, such as Internet Explorer, Google Chrome, or Mozilla Firefox. You need the web address or URL of your team site, which you can get from your primary SharePoint administrator or IT department. You also need a network user account with permissions to access the team site.
To access your team site:
Open your web browser.
Type the web address for your team site in the address bar and press Enter.
Header: The header spans the entire top of the page. The header in a SharePoint page acts much like the menu in a traditional Windows application, such as Microsoft Word. SharePoint 2013 even features the Ribbon in the page header, similar to how the Ribbon appears in the top of many Office applications.
Left navigation pane: The navigation pane provides quick access to the site’s document libraries, lists, and discussion boards. You can even add links to content you create, such as documents and web pages.
Page content: The content displays in the body of the page.
Generally speaking, the header and left navigation pane stay fairly consistent, whereas the body of the page changes to display the content for the webpage. This is very similar to how most websites work.
Microsoft has spent a lot of money on usability research to determine how best to lay out the pages in SharePoint. Save time by using the layouts provided by Microsoft instead of creating your own custom layouts for team sites.
