All fonts are sized in relative units. This means that font sizes can be easily increased in all browsers. Modern browsers (e.g. Firefox, Chrome, Internet Explorer 11, and Safari) allow web pages to be magnified by holding down CTRL and type “+” or “-“. To return text to normal hold down CTRL and type “0”. This method works on most web sites if they have been properly coded.
In older versions of Internet Explorer such as IE7, the size of the text on a page can be increased by going to the View menu and selecting Text Size and then Largest.
