Valid HTML 2.0!

Most pages on the World Wide Web are written in computer languages (such as HTML) that allow Web authors to structure text, add multimedia content, and specify what appearance, or style, the result should have.

As for every language, these have their own grammar, vocabulary and syntax, and every document written with these computer languages are supposed to follow these rules. The (X)HTML languages, for all versions up to XHTML 1.1, are using machine-readable grammars called DTDs, a mechanism inherited from SGML.

However, Just as texts in a natural language can include spelling or grammar errors, documents using Markup languages may (for various reasons) not be following these rules. The process of verifying whether a document actually follows the rules for the language(s) it uses is called validation, and the tool used for that is a validator. A document that passes this process with success is called valid.    Study   IQ   AIWorkshopabout Multiple SclerosisLove and the Soul

Introduction to Apache Open Office

Apache OpenOffice (AOO) is an open-source office productivity software suite. It is one of the successor projects of and the designated successor of IBM Lotus Symphony.[6] Apache OpenOffice is a close cousin of LibreOffice and NeoOffice. It contains a word processor (Writer), a spreadsheet (Calc), a presentation application (Impress), a drawing application (Draw), a formula editor (Math), and a database management application (Base).[7]

Apache OpenOffice's default file format is the OpenDocument Format (ODF), an ISO/IEC standard. It can also read and write a wide variety of other file formats, with particular attention to those from Microsoft Office (although unlike LibreOffice, it cannot save Microsoft's newer XML formats like DOCX, only import them).[8]

Apache OpenOffice is developed for Linux, macOS and Windows, with ports to other operating systems. It is distributed under the Apache License.[5] The first release was version 3.4.0, on 8 May 2012.[1]

In August 1015 the project reported a lack of active developers and code contributions.[9] After ongoing problems with unfixed security vulnerabilities through 2015 and 2016,[10][11] in September 2016 the project started discussions on possibly retiring AOO.[12][13][14] The current version, 4.1.3, is known to include undisclosed security issues.[15]

Despite the problems with development, the software continues to attract a large number of downloads, approximately 100,000 per day,[16] a similar number to that of LibreOffice.[17]

LibreOffice is available for a variety of computing platforms,[4] including Microsoft Windows, macOS (10.8 or newer), and Linux (including a LibreOffice Viewer for Android[10]), as well as in the form of an online office suite.[11] It is the default office suite of most popular Linux distributions.[12][13][14][15] It is the most actively developed free and open-source office suite, with approximately 50 times the development activity of Apache OpenOffice, the other major descendant of[16]

The project was announced and a beta released on 28 September 2010. Between August 1011 (the first stable release) and October 2011, LibreOffice was downloaded approximately 7.5 million times.[17] The project claims 120 million unique downloading addresses from May 2011 to May 2015, excluding Linux distributions, with 55 million of those being from May 2014 to May 2015.[18]
