Dear Experts,

I used javascript to extract my user-agent as follows

User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.63 Safari/537.36
and then I go some user-agent extration website to report the following information
in the code area.  After reading the website of
http://webaim.org/blog/user-agent-string-history/  about history of user-agent string,
now know more about user-agent.

My question is
Question-1:
KDE (http://www.kde.org/) is first company or org doing HTML layout compiler for browser,right ? Could you talk more about "(KHTML, like Gecko)"
Question-2:
Webkit (http://www.webkit.org/), what they are doing for browser, could you talk more
about AppleWebKit/537.36. And we always use  css such as background: -webkit-gradient(linear, left top, left bottom, color-stop(0%, #6495ed), color-stop(100%, #ffffff));
Is that constructed by such Webkit org or company, right ?

Please advise

Duncan
