What is it?
SiteShow is a very easy to use, self-contained HTML/CSS/Javascript page that facilitates a slideshow of web pages. Each web page becomes a “slide” in the show. The pages can be your own web content, direct links to images, or any other web page on the Internet.
See it in action! See the source code
Things you should know
SiteShow uses an IFRAME to contain the slide pages. If any of your slide pages have script to force itself out of a frameset, the page will obviously break the show.
If any of your slide pages are slow loading, it detracts from the show’s effect. Not my problem. 🙂 I designed the show for use on an Intranet for display in a company’s lobby. In this environment, the show works fantastic.
SiteShow works best in IE. I welcome suggestions to make it work better in Mozilla/Firefox. The issues in Firefox are:
- The fading in and out is a bit jerky. It is smooth in IE.
- The SiteShow body background color is inherited by the slide pages. This can produce undesirable results. This is not a problem in IE.
TIP: Use SiteShow in your browser’s full-screen mode (F11 key).
Features
- Easily define as many slides as you want. For each, you specify a title, URL, and duration time in seconds.
- SiteShow Menu allows people to pause, play, or go directly to any specific slide. The menu auto-fades in on page mouseover. It auto fades-out after a few seconds.
- Modify the fade out color by changing the CSS background-color.
- Requires zero server-side code. Entire utility is contained in a single, simple, client-side page.
How do I use it?
Simply copy the page source below into a new HTML file then edit the slides[] array in the Javascript.
