Current Background Images
There are currently 100+ background images available on www.pa.msu.edu for use in your documents. Background images are declared in the body tag of an HTML source document as follows:
Background images are usually "gif"-type or "jpg"-type. These file types differ in that they have different compression techniques, thus different rendering quality.
This demonstration also shows what is called "client pull" . This feature uses META tags. In brief, the client-side browser interprets the META tag and follows the appropraite directive. In this case, the META tag is used to pull the next document from the server as follows;
In essence, the HTML file which is currently being viewed waits for approx. 6 seconds, then "refreshes" the window with the document declared in the META tag. I have used a similar tag to deliver a short sound file of an old project from a few years back. I modified the url attribute of the META tag so that the sound file would be delivered as soon as the document is completely loaded. Thus, reducing the "refresh" time from 6, as above, to 0.
With that in mind, you can also deliver a sound file of the current homework due, for example.
The background images are declared in the same amout of HTML files. Each file
calls a different background. To stop the automatic scrolling, simply choose
the link to the particular image. This link appears in the first line. The
"Next" link takes you to the next document in series. To exit out of
the demo, the smily
is present.
Click on this image at any time during the demo and you will return to this
page.
To use one of these images in your own page, simply declare the path to it in the body tag of your document, i.e. <body background="/backgrounds/filename.yyy">.
The scrolling will continue on it's own until the last file is "pulled" by the client. For this reason, here are various starting points:
