<!DOCTYPE html> <html> <head> <style> h1 { font-size: 2.5em; /* 40px/16=2.5em */ } h2 { font-size: 1.875em; /* 30px/16=1.875em */ } p { font-size: 0.875em; /* 14px/16=0.875em */ } </style> </head> <body> <h1>This is heading 1</h1> <h2>This is heading 2</h2> <p>This is a paragraph.</p> <p>Specifying the font-size in em allows all major browsers to resize the text. Unfortunately, there is still a problem with older versions of IE. When resizing the text, it becomes larger/smaller than it should.</p> </body> </html>
