Internet Explorer 6 (IE6) was released on 27 August 2001, more than 8 years ago, and is the default browser shipped with Windows XP. The market share of this browser continues to decline, now being below 14% globally and less than 7% in Europe and USA. This version of Internet Explorer (IE) has several problems:
- Does not support PNG transparencies
- Contains errors when using float + margin / padding
- Inability to use pseudo-classes and pseudo-elements.
- Incomplete support of CSS 2.1
- Presents display errors
Developing systems or websites with IE6 compatibility means spending hours to solve displaying bugs and limit the designs so that they appear correctly in this browser. Besides the user experience is limited to the possibilities available in IE6, modern browsers (IE7, IE8, Firefox 3.5, Safari 4, Google Chrome, Opera 10, etc.) can offer a much better online experience.
It is because of this that from March 2010 IE6 won’t have support on systems and sites developed by Serfe. This means that if you want to have support for this version of Internet Explorer, you must explicitly request it.
