You can use the Web to give others access to your presentation by publishing (publish: To save a copy of a file in Hypertext Markup Language (HTML) format to a Web server.) it to a Web server (Web server: A computer that hosts Web pages and responds to requests from browsers. Also known as an HTTP server, a Web server stores files whose URLs begin with http://.) or another computer that is accessible to those you want to view the presentation with a Web browser (browser: Software that interprets HTML files, formats them into Web pages, and displays them. A Web browser, such as Windows Internet Explorer, can follow hyperlinks, transfer files, and play sound or video files that are embedded in Web pages.). When you publish a presentation, a copy of it is created in a file location you choose. You can publish from a presentation that is in .ppt format or that is saved as a Web page (Web page: A presentation saved in HTML format. Supporting graphics and other related files are stored in an associated folder when a presentation is saved as a Web page.) or Single File Web page (Single File Web Page (MHTML): An HTML document saved in MHTML format, which integrates inline graphics, applets, linked documents, and other supporting items referenced in the document.).

When you publish your presentation to the Web or save it as a Web page, your presentation automatically includes the following:
A navigation frame, which is the outline of the presentation.
A slide frame.
A control for showing or hiding the outline of the presentation.
A control for showing or hiding the notes pane.
A full-screen viewing option, which hides the browser controls and is similar to slide show view (view: A way of displaying the contents of a presentation and providing the user with the means to interact with it.) in Microsoft PowerPoint. If you have custom shows (custom show: A presentation within a presentation in which you group slides in an existing presentation so that you can show that section of the presentation to a particular audience.) in your presentation, they can be viewed only in full-screen mode.
Publish a presentation when you want to do any of the following:
- Make available on the Web a copy of a presentation that you can edit and update (you can keep your original work in the PowerPoint presentation [.ppt] format)
- Publish copies of the same presentation to different Web locations
- Make a subset of your presentation available (for example, a custom show, a single slide, or a range of slides)
- Customize the presentation to view best in a particular browser or browser version, such as Microsoft Internet Explorer 5.01 or later or Netscape Navigator 3.0
- Choose which elements, such as speaker notes (notes pane: The pane in normal view in which you type notes that you want to accompany a slide. You print these notes as notes pages or have them display when you save a presentation as a Web page.), animations (animate: To add a special visual or sound effect to text or an object. For example, you can have your text bullet points fly in from the left, one word at a time, or hear the sound of applause when a picture is uncovered.), and navigation buttons, will appear in the Web version of the presentation
