HTML slideshows display a series of images in succession, changing when users click buttons or a timer. They can be created using HTML alone or a combination of languages like JavaScript and Flash. Basic presentations use HTML links, while timed ones use meta tags. Combining languages allows for more functionality, including zoom, pan, and slide thumbnails. Creating feature-rich presentations requires knowledge of multiple programming languages, but plug-ins are available to simplify the process.
A slideshow in Hypertext Markup Language (HTML) is a series of images displayed in succession using a web browser. The images in an HTML slideshow change when a user clicks a button to view the next or previous slides, or based on a timer . Also, some presentations combine a timer with user controls. HTML presentations can be encoded using HTML alone or a combination of HTML and other languages, such as JavaScript and Flash®. Depending on the types of code used to create the HTML presentation, the presentation might include additional features, such as zoom capabilities and the ability to view an entire presentation on the same web page.
Basic HTML presentation allows a viewer to click links or buttons that take you to the next or previous slide and uses HTML code only. This type of presentation does not use a timer or provide additional features, such as the ability to zoom in on a slide. To create this type of presentation, one HTML page is created per slide and each page provides links that a user clicks to advance through the presentation. Each slide can contain images, captions and additional text. Presentation pages should be designed using similar styles or the same HTML page templates, which allow the viewer to perceive the content as a presentation, rather than separate web pages.
You can create a timed HTML presentation using the http-equiv refresh HTML meta tag. Additional user controls can be added, including buttons that allow the user to go to the next image or go back to the previous one. Like the basic HTML presentation, one HTML page is created per slide. The Web developer adds the http-equiv refresh meta tag to each slide’s HTML page and defines the number of seconds to wait before loading the next slide by adding the content parameter to the meta tag. The Uniform Resource Locator (URL) that identifies the location of the next slide is also found in the meta tag using the URL parameter.
Most HTML presentations are created using a combination of languages, including HTML, Flash®, JavaScript, jQuery, and cascading style sheets (CSS). These presentations provide more functionality than HTML-only ones. In addition to timed slides and user controls that allow viewers to skip slides, you can add zoom, pan, and built-in slide thumbnails. Slide thumbnails are especially useful for presentations containing a large number of slides, as each clickable thumbnail shows a preview of the linked slide and allows the user to jump to any slide they want to view. Also, using additional languages allows website designers to embed an entire slide presentation into a single web page.
Adding a feature-rich HTML presentation using a mix of languages requires the website designer to know at least two programming languages. Fortunately, the code needed to create these presentations is printed in web programming books and freely available online. Also, some content management systems (CMS) support adding plug-ins, and some presentation plug-ins are available. These plug-ins allow you to add an HTML or multilingual presentation to a web page without learning HTML or other languages.
