-                <p>Launched by a <strong>Saturn V</strong> rocket from <a href="http://en.wikipedia.org/wiki/Kennedy_Space_Center" title="Kennedy Space Center">Kennedy Space Center</a> in Merritt Island, Florida on July 16, Apollo 11 was the fifth manned mission of <a href="http://en.wikipedia.org/wiki/NASA" title="NASA">NASA</a>&#39;s Apollo program. The Apollo spacecraft had three parts:</p>
-                <ol>
-                        <li><strong>Command Module</strong> with a cabin for the three astronauts which was the only part which landed back on Earth</li>
-                        <li><strong>Service Module</strong> which supported the Command Module with propulsion, electrical power, oxygen and water</li>
-                        <li><strong>Lunar Module</strong> for landing on the Moon.</li>
-                </ol>
-                <p>After being sent to the Moon by the Saturn V&#39;s upper stage, the astronauts separated the spacecraft from it and travelled for three days until they entered into lunar orbit. Armstrong and Aldrin then moved into the Lunar Module and landed in the <a href="http://en.wikipedia.org/wiki/Mare_Tranquillitatis" title="Mare Tranquillitatis">Sea of Tranquility</a>. They stayed a total of about 21 and a half hours on the lunar surface. After lifting off in the upper part of the Lunar Module and rejoining Collins in the Command Module, they returned to Earth and landed in the <a href="http://en.wikipedia.org/wiki/Pacific_Ocean" title="Pacific Ocean">Pacific Ocean</a> on July 24.</p>

-/**
- * CSS classes applied to aligned images. Useful to take control over the way
- * the images are aligned, i.e. to customize output HTML and integrate external stylesheets.
- *
- * Classes should be defined in an array of three elements, containing left, center, and right
- * alignment classes, respectively. For example:
- *
- *              config.image2_alignClasses = [ 'align-left', 'align-center', 'align-right' ];
- *
- * **Note**: Once this configuration option is set, the plugin will no longer produce inline
- * styles for alignment. It means that e.g. the following HTML will be produced:
- *
- *              <img alt="My image" class="custom-center-class" src="foo.png" />
- *
- * instead of:
- *
- *              <img alt="My image" style="float:left" src="foo.png" />
- *
- * **Note**: Once this configuration option is set, corresponding style definitions
- * must be supplied to the editor:
- *
- * * For [classic editor](#!/guide/dev_framed) it can be done by defining additional
- * styles in the {@link CKEDITOR.config#contentsCss stylesheets loaded by the editor}. The same
- * styles must be provided on the target page where the content will be loaded.
- * * For [inline editor](#!/guide/dev_inline) the styles can be defined directly
- * with `<style> ... <style>` or `<link href="..." rel="stylesheet">`, i.e. within the `<head>`
- * of the page.
- *
- * For example, considering the following configuration:
- *
- *              config.image2_alignClasses = [ 'align-left', 'align-center', 'align-right' ];
- *
- * CSS rules can be defined as follows:
- *
- *              .align-left {
- *                      float: left;
- *              }
- *
- *              .align-right {
- *                      float: right;
- *              }
- *
- *              .align-center {
- *                      text-align: center;
- *              }
- *
- *              .align-center > figure {
- *                      display: inline-block;
- *              }
- *
- * Read more in the [documentation](#!/guide/dev_captionedimage) and see the
- * [SDK sample](http://sdk.ckeditor.com/samples/captionedimage.html).
- *
- * @since 4.4
- * @cfg {String[]} [image2_alignClasses=null]
- * @member CKEDITOR.config
- */
-/**
- * Determines whether alternative text is required for the captioned image.
- *
- *              config.image2_altRequired = true;
