Small self-contained websites can be submitted as additional files, in such a way that they will be browsable from within the full text HTML version of the article. In order to do this, please follow these instructions:
Create a folder containing a starting file called index.html (or index.htm) in the root. Put all files necessary for viewing the mini-website within the folder, or sub-folders.
Ensure that all links are relative (ie “images/picture.jpg” rather than “/images/picture.jpg” or “http://yourdomain.net/images/picture.jpg” or “C:\Documents and Settings\username\My Documents\mini-website\images\picture.jpg”) and no link is longer than 255 characters.
Access the index.html file and browse around the mini-website, to ensure that the most commonly used browsers (Internet Explorer and Firefox) are able to view all parts of the mini-website without problems, it is ideal to check this on a different machine.
Compress the folder into a ZIP, check the file size is under 20 MB, ensure that index.html is in the root of the ZIP, and that the file has .zip extension, then submit as an additional file with your article.
