Modern browsers are now the vast percentage of website users and it is quite safe to use advanced features from CSS3 to some HTML5 as well as one of the most needed features which is using fonts the user didn’t have in its computer. Google is making a great effort on enabling and easing this feature to all web developers by releasing a huge collection of open source fonts created by great typographers that generously have shared them.
