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

Mozilla/5.0 They claim that it is based on Mozilla user agent (only true for Gecko browsers). It is now used only for historical reasons.Windows NT 6.1 OS signatureWOW64 Windows running on a 64-bit processor signatureAppleWebKit/537.36 Open source application framework ver. 537.36(KHTML, like Gecko) HTML layout engine developed by the KDE projectChrome/31.0.1650.63 browser signatureSafari/537.36 browser signature 1:2:3:4:5:6:7:

Yes, KDE was the first organization to write code specifically for that web browser. Then Apple started working on it and then it was made an open source project under the name Webkit to which Google also has made significant contributions.
"Gecko" refers to the rendering engine by Mozilla, which is used in many browsers, most notably of which is Firefox. The phrases "Mozilla/5.0" and "like Gecko" are both used so old and very poorly written browser sniffers which only recognize Internet Explorer and Mozilla browsers will treat Webkit browsers as they would true Mozilla browsers. (I should mention that browser sniffing is a practice that should be avoided as much as possible.)
"-webkit-gradient()" is a CSS3 prefixed value. To speed up the creation of new CSS standards, browser vendors each have a vendor prefix for use when implementing experimental features (some being much more experimental than others) before the the draft of whichever CSS3 module they belong to is completed. Vendor prefixes include "-webkit-", "-khtml-", "-moz-" for Mozilla, "-ms-" for Microsoft, and "-o-" for Opera.
@Dave, I expect Duncan means "rendering engine", not "compiler".

KDE is a desktop GUI for Linux with a lot of utility programs. I've never heard of an HTML compiler from them. The only HTML compiler I know of is the Help Compiler for Windows. In addition, browsers need to get an un-compiled plain text version of a web page.
Gecko is the Mozilla page rendering 'engine' for Firefox, SeaMonkey, and other Mozilla browsers.
Webkit is a rendering engine like Gecko is and this page http://www.webkit.org/ says that it was derived from KDE. Webkit is also used by Apple products and Google Chrome. When you see something that starts with "-webkit-" the designer is trying to use a non-standard feature of the Webkit rendering engine. Mozilla features start with "-moz".
And there are thousands of User Agent Strings. http://www.useragentstring.com/pages/useragentstring.php
