! 47: <h3 id="about">About this Service</h3>
! 48:
! 49: <h4 id="what">What is this? Do I need it?</h4>
! 50:
! 51: <p>The W3C CSS Validation Service is a free software created by the W3C
! 52: to help Web designers and Web developers check Cascading Style Sheets (CSS).
! 53: It can be used on this <a href="./">free service</a> on the web, or downloaded
! 54: and used either as a java program, or as a java servlet on a Web server.</p>
! 55:
! 56: <p>Do <em>you</em> need it? If you are a Web developer or a Web designer, this
! 57: tool will be an invaluable ally. Not only will it compare your style sheets to the
! 58: CSS specifications, helping you find errors, typos, or incorrect uses of CSS, it will
! 59: also tell you when your CSS poses some risks in terms of usability.</p>
! 60:
! 61: <h4 id="help">The explanation above is incomprehensible! Help!</h4>
! 62: <p>Most documents on the Web are written in a computer language called HTML. This language
! 63: can be used to create pages with structured information, links, and multimedia objects. For
! 64: color, text, and layout, HTML uses a styling language called CSS, short for "Cascading Style Sheets".
! 65: What this tool does is help people authoring CSS check, and fix if necessary, their CSS Style Sheets.</p>
! 66:
! 67: <h4 id="reference">So, this is the authority on what is correct CSS and what isn't?</h4>
! 68: <p>No. It is a helpful and reliable tool, but a software tool, and like every software, it has some
! 69: <a href="http://www.w3.org/Bugs/Public/buglist.cgi?product=CSSValidator">bugs and issues</a>.
! 70: The actual reference on Cascading Style Sheets are the <a href="http://www.w3.org/Style/CSS/#specs">CSS
! 71: Specifications</a>.</p>
! 72:
! 73: <h4 id="free">How much does it cost?</h4>
! 74: <p>Nothing. The service is free. The source is <a href="DOWNLOAD.html">open</a> and you are free
! 75: to download it, use it, modify it, distribute it,
! 76: and <a href="http://www.w3.org/Consortium/Legal/copyright-software">more</a>.
! 77: If you really like it, you are welcome to <a href="#participate">join the project</a> or donate to W3C via the
! 78: <a href="http://www.w3.org/Consortium/sup">W3C supporters program</a>, but nobody forces you to.</p>
! 79:
! 80: <h4 id="who">Who wrote this tool? Who maintains it?</h4>
! 81: <p>W3C maintains and hosts the tool, thanks to the work and contributions by W3C staff,
! 82: volunteer developers and translators. See the <a href="thanks.html">credits and acknowledgments page</a>
! 83: for details. <a href="#participate">You too can help</a>.</p>
! 84:
! 85: <h4 id="participate">Can I help?</h4>
! 86: <p>Of course. If you are a java programmer, you can help the CSS Validator project by
! 87: checking out the <a href="#code">code</a>,
! 88: adopting and fixing <a href="http://www.w3.org/Bugs/Public/buglist.cgi?product=CSSValidator">bugs</a>,
! 89: or helping build new features.</p>
! 90: <p>But you do not need to be a coder to help build and maintain this tool: you can also help improve the
! 91: documentation, participate in translating the validator in your language, or subscribe to the
! 92: <a href="http://lists.w3.org/Archives/Public/www-validator-css/">mailing-list</a> and discuss about the tool
! 93: or help other users.</p>
! 94:
! 95: <h4 id="contact">Any other question?</h4>
! 96: <p>If you have any question regarding CSS or the CSS validator, check out the available
! 97: <a href="Email">mailing-lists and forums</a>. But before that, make sure that your question
! 98: or comment is not covered already by the <a href="http://www.websitedev.de/css/validator-faq">CSS Validator
! 99: <acronym title="Frequently Asked Questions">FAQ</acronym> document</a>.</p>

! 103: <h4 id="code">What is the CSS Validator written in? Is the source available somewhere?</h4>
! 104: <p>The W3C CSS validator is written using the java language, and yes, its source
! 105: is available, using CVS: you can
! 106: <a href="http://dev.w3.org/cvsweb/2002/css-validator/">browse the code online</a>
! 107: or follow the instructions there to download the whole source tree. For a quick
! 108: overview of the classes used in the CSS Validator code, check out the
! 109: <a href="README.html">README</a> file.</p>
! 110:
! 111: <h4 id="install">Can I install and run the CSS Validator myself?</h4>
! 112: <p>It is possible to download and install the CSS validator, and to run it either from the command line, or
! 113: as a servlet in a Web server. Read the <a href="RUN.html">instructions</a> for installation and use.</p>
! 114:
! 115: <h4 id="api">Can I build an application upon this validator? Is there an API?</h4>
! 116: <p>Yes, and <a href="api">yes</a>. The CSS Validator has a (RESTful) <a href="api">SOAP interface</a>
! 117: which should make it reasonably easy to build applications (Web or otherwise) upon it. Good manners and
! 118: respectful usage of shared resources are of course customary: make sure your applications sleep() between
! 119: calls to the validator, or install and run your own instance of the validator.</p>
