SharePoint 2013: OOTB Behind the Scenes 1

In this blog, I am going to give some information on default font family used by the SharePoint 2013.
 
When I am investigating the OOTB corev15.css file, I have found the same font is used for different areas like heading, body area, navigation etc... Based on my analysis I have summarized the default font-family used by the SharePoint 2013.
 
Body, Small Headings (h4), Navigation:
  1. font-family: "Segoe UI","Segoe",Tahoma,Helvetica,Arial,sans-serif;  
Large Heading Content (h1), Large Title:
  1. font-family: "Segoe UI Light","Segoe UI","Segoe",Tahoma,Helvetica,Arial,sans-serif;  
Heading Content (h2, h3), Large Body:
  1. font-family: "Segoe UI Semilight","Segoe UI","Segoe",Tahoma,Helvetica,Arial,sans-serif;  
Ribbon:
  1. font-family: "Segoe UI",Tahoma,Verdana,sans-serif;  
Content Menu:
  1. font-family: "Segoe UI",Tahoma,Verdana,Arial,Sans-Serif;  
I'll include more details in upcoming blog posts. Stay tuned :)
