Description: 

Support for the -khtml- prefix has been removed from Drupal core. The khtml prefix was used by the Konqueror engine, but Konqueror has less than 1% of browser share, and Konqueror can now optionally use the Webkit engine instead.

When writing CSS, simply just omit extra CSS properties for the -khtml- prefix.
