The last version of Internet Explorer, version 11, was released on October 17, 2013. This is a very long time ago when taking into account the rapid development of web technologies. These days it is often difficult and time consuming to get modern technologies to work well in this old browser. More and more frameworks are dropping support, and even Microsoft themselves has announced that they will fully drop support for IE in their own services in 2021.
Consequently, we have decided to not include support for IE in the Design Library website.
Use "regular" FontAwesome icons for sizes up to 32 px
As of 2019-09-04, we are changing the recommendation on using icons:
Originally the “light” version of FontAwesome icons was recommended as it aligns well with our brand. We have since then learned that the lines look too subtle in smaller sizes. This is a small but important shift to make our icons clearer for our users.
Everything else stays the same (i.e "use these icons up to 32 px", "choose icons freely but avoid icons that are framed in circle/square", etc).
Please let us know if you have any questions or input.
