• The CERN logo should always be an active link to http://cern.ch
• The CERN logo should not be animated or have states (such as :hover or :focus) or scripted interactions

• The logo should be no less than 60px wide, and its correct proportions must be respected
• Observe the general guidelines for use of the CERN logo, such as minimum spacing and colour restrictions
