| Perbandingan -- layout engines (non-standard HTML)The following tables compare deprecated and proprietary HTML elements and attributes compatibility and support for a number of layout engines. Please see the individual products' articles for further information. This article is not all-inclusive or necessarily up-to-date. Unless otherwise specified in footnotes, comparisons are based on the stable versions without any add-ons, extensions or external programs. In the early years of the World Wide Web, the standards which today are used in most web browsers and web pages were mostly non-existent. Different browsers and HTML editors were being offered by competing vendors such as Netscape, Microsoft and WebTV, all of whom had their own ideas for how web sites should be constructed. These varying features resulted in web developers coding for specific web browsers, using elements which could often be recognized by only one browser. The WebTV and IBM WebExplorer inventions have never seen adoption by mainstream browsers. Explanation of the tables Engine nomenclatureRather than the names of web browsers, the names of the underlying engines are used. The browsers that use the various engines are listed below. | Layout engine | Release version | Preview version | Used by |

Supported values are implemented correctly. | | Incorrect | Indicates that the property/element is understood, but that it is not implemented correctly in all cases. | | Experimental | Indicates that the property/element is understood, but supported under an alternate name. May be incomplete or buggy. | | Dropped | Indicates that the property/element is no longer supported. | | Nightly build | Indicates that the property/element is supported to some extent in an experimental/nightly build.
