A plain version of the OSD without annotations can be found <a href="http://www.opensource.org/docs/osd">here</a>.</div><h2>Introduction</h2>Open source doesn't just mean access to the <a class="zem_slink" href="http://en.wikipedia.org/wiki/Source_code" rel="wikipedia nofollow" target="_blank" title="Source code">source code</a>. The distribution terms of <a class="zem_slink" href="http://en.wikipedia.org/wiki/Open_source_software" rel="wikipedia nofollow" target="_blank" title="Open source software">open-source software</a> must comply with the following criteria:<br /><h3>1. Free Redistribution</h3>The license shall not restrict any party from selling or giving away the software as a component of an aggregate software distribution containing programs from several different sources. The license shall not require a royalty or other fee for such sale.<br /><div class="annotation"><b>Rationale:</b> By constraining the license to require free redistribution, we eliminate the temptation to throw away many long-term gains in order to make a few short-term sales dollars. If we didn't do this, there would be lots of pressure for cooperators to defect.</div><h3>2. Source Code</h3>The program must include source code, and must allow distribution in source code as well as compiled form. Where some form of a product is not distributed with source code, there must be a well-publicized means of obtaining the source code for no more than a reasonable reproduction cost preferably, downloading via the Internet without charge. The source code must be the preferred form in which a programmer would modify the program. Deliberately obfuscated source code is not allowed. Intermediate forms such as the output of a preprocessor or translator are not allowed.<br /><div class="annotation"><b>Rationale:</b> We require access to un-obfuscated source code because you can't evolve programs without modifying them. Since our purpose is to make evolution easy, we require that modification be made easy.</div><h3>3. <a class="zem_slink" href="http://en.wikipedia.org/wiki/Derivative_work" rel="wikipedia nofollow" target="_blank" title="Derivative work">Derived Works</a></h3>The license must allow modifications and derived works, and must allow them to be distributed under the same terms as the license of the original software.<br /><div class="annotation"><b>Rationale:</b> The mere ability to read source isn't enough to support independent peer review and rapid evolutionary selection. For rapid evolution to happen, people need to be able to experiment with and redistribute modifications.</div><h3>4. Integrity of The Author's Source Code</h3>The license may restrict source-code from being distributed in modified form <i>only</i> if the license allows the distribution of "patch files" with the source code for the purpose of modifying the program at build time. The license must explicitly permit distribution of software built from modified source code. The license may require derived works to carry a different name or version number from the original software.<br /><div class="annotation"><b>Rationale:</b> Encouraging lots of improvement is a good thing, but users have a right to know who is responsible for the software they are using. Authors and maintainers have reciprocal right to know what they're being asked to support and protect their reputations.<br /><br />Accordingly, an <a class="zem_slink" href="http://en.wikipedia.org/wiki/Open_source_license" rel="wikipedia nofollow" target="_blank" title="Open source license">open-source license</a> must guarantee that source be readily available, but may require that it be distributed as pristine base sources plus patches. In this way, "unofficial" changes can be made available but readily distinguished from the base source.</div><h3>5. No Discrimination Against Persons or Groups</h3>The license must not discriminate against any person or group of persons.<br /><div class="annotation"><b>Rationale:</b> In order to get the maximum benefit from the process, the maximum diversity of persons and groups should be equally eligible to contribute to open sources. Therefore we forbid any open-source license from locking anybody out of the process.<br /><br />Some countries, including the <a class="zem_slink" href="http://maps.google.com/maps?ll=38.8833333333,-77.0166666667&spn=10.0,10.0&q=38.8833333333,-77.0166666667%20(United%20States)&t=h" rel="geolocation nofollow" target="_blank" title="United States">United States</a>, have export restrictions for certain types of software. An OSD-conformant license may warn licensees of applicable restrictions and remind them that they are obliged to obey the law; however, it may not incorporate such restrictions itself.</div><h3>6. No Discrimination Against Fields of Endeavor</h3>The license must not restrict anyone from making use of the program in a specific field of endeavor. For example, it may not restrict the program from being used in a business, or from being used for genetic research.<br /><div class="annotation"><b>Rationale:</b> The major intention of this clause is to prohibit license traps that prevent open source from being used commercially. We want commercial users to join our community, not feel excluded from it.</div><h3>7. Distribution of License</h3>The rights attached to the program must apply to all to whom the program is redistributed without the need for execution of an additional license by those parties.<br /><div class="annotation"><b>Rationale:</b> This clause is intended to forbid closing up software by indirect means such as requiring a non-disclosure agreement.</div><h3>8. License Must Not Be Specific to a Product</h3>The rights attached to the program must not depend on the program's being part of a particular software distribution. If the program is extracted from that distribution and used or distributed within the terms of the program's license, all parties to whom the program is redistributed should have the same rights as those that are granted in conjunction with the original software distribution.<br /><div class="annotation"><b>Rationale:</b> This clause forecloses yet another class of license traps.</div><h3>9. License Must Not Restrict Other Software</h3>The license must not place restrictions on other software that is distributed along with the licensed software. For example, the license must not insist that all other programs distributed on the same medium must be open-source software.<br /><div class="annotation"><b>Rationale:</b> Distributors of open-source software have the right to make their own choices about their own software.<br /><br />Yes, the GPL v2 and v3 are conformant with this requirement. Software linked with <a class="zem_slink" href="http://en.wikipedia.org/wiki/GNU_General_Public_License" rel="wikipedia nofollow" target="_blank" title="GNU General Public License">GPLed</a> libraries only inherits the GPL if it forms a single work, not any software with which they are merely distributed.</div><h3>10. License Must Be Technology-Neutral</h3>No provision of the license may be predicated on any individual technology or style of interface.<br /><div class="annotation"><b>Rationale:</b> This provision is aimed specifically at licenses which require an explicit gesture of assent in order to establish a contract between licensor and licensee. Provisions mandating so-called "click-wrap" may conflict with important methods of software distribution such as FTP download, <a class="zem_slink" href="http://en.wikipedia.org/wiki/CD-ROM" rel="wikipedia nofollow" target="_blank" title="CD-ROM">CD-ROM</a> anthologies, and web mirroring; such provisions may also hinder code re-use. Conformant licenses must allow for the possibility that <b>(a)</b> redistribution of the software will take place over non-Web channels that do not support click-wrapping of the download, and that <b>(b)</b> the covered code (or re-used portions of covered code) may run in a non-GUI environment that cannot support popup dialogues.</div></div></div></div></div><div class="clearfix"></div></div></div></div></div></div><div class="block block-block clearfix" id="block-block-11"><div class="content"><a href="http://creativecommons.org/licenses/by/3.0/" rel="license"><img alt="Creative Commons License" src="http://i.creativecommons.org/l/by/3.0/88x31.png" style="border-width: 0;" /></a><br />Opensource.org site content is licensed under a <a href="http://creativecommons.org/licenses/by/3.0/" rel="license">Creative Commons Attribution 3.0 License</a>. | <a href="http://opensource.org/ToS">Terms of Service</a> </div></div><div class="zemanta-pixie"><img alt="" class="zemanta-pixie-img" src="http://img.zemanta.com/pixy.gif?x-id=4e017e85-3d45-442a-92c1-ed81d7e5b5ce" /></div>

HTML Background Code

<div dir="ltr" style="text-align: left;" trbidi="on"><div dir="ltr" style="text-align: left;" trbidi="on">This page contains HTML background code. Feel free to copy and paste the HTML background code into your own website, blog, MySpace page, or other HTML document.

Strictly speaking, this is a CSS property but you use it in conjunction with your HTML code. The <code>background</code> property is a shorthand property for setting all background properties at once. <br /><table border="0" cellspacing="0" class="example"><tbody><tr><th>Source Code</th><th>Result</th></tr><tr><td><textarea class="exampleCode" cols="70" name="bodyText" rows="3" style="height: 91px; width: 386px;"><!-- Codes by HTMLcodes.me --> <div style="background:#eee url(http://1.bp.blogspot.com/-_aidXOZSyS8/UTg3Gxg40II/AAAAAAAAEKs/cYFzSKP-XMo/s1600/DSCF0494.JPG) repeat fixed; overflow:scroll; width:200px; height:100px;"><p>This example sets all the background properties with one property - the 'background' property.

This example sets all the background properties with one property - the 'background' property. This keeps the code shorter and easier to read.

Page Background

To set the background for the whole page, simply apply the background property against the body tag.
Example:
<body style="background:#eee url(http://1.bp.blogspot.com/-_aidXOZSyS8/UTg3Gxg40II/AAAAAAAAEKs/cYFzSKP-XMo/s1600/DSCF0494.JPG) repeat fixed;"> ... </body>

Alternative Background Codes

Below are more HTML background codes. In these examples, instead of using the background shorthand property, we use a property more specific to the actual effect we want to achieve. Doing this is simply an alternative - it's your choice which method you use.

Background Color

This example code applies a background color to a p tag using the background-color property. You can apply background color to any other HTML element, such as a div tag, body tag etc. Here, we also apply color to the text by using the color property.
Choose a color with the HTML color picker.

Source Code	Result
<!-- Codes by HTMLcodes.me --> <p style="background-color:#0f0;color:black;width:200px;">This text has got a background color applied. You could also apply background color to the whole page if you like.</p>	This text has got a background color applied. You could also apply background color to the whole page if you like.

Background Image

This example code applies a background color to a p tag using the background-color property. You can apply background color to any HTML element, such as a div tag, body tag etc. Here, we also apply color to the text by using the color property.

You could also apply a background image to the whole page if you like.</div>	This div tag has got a background image. You could also apply a background image to the whole page if you like.

Fixed Background Image

You can fix the background image so that it doesn't scroll when you scroll the div (or page, as the case may be).
