Advantages of documentation that is written using only HTML and CSS for formatting include:
- Independent of operating system and web browser
- Cheap and easy to distribute (typically supplied over the Internet)
- Relatively simple to implement.
However, some problems exist:
- Page formatting is difficult and restricted
- If supplied over the Internet, large graphics take a relatively long time to download
- It is not suitable for extended reading (this applies to all forms of online help)
- Navigation and search features are restricted. (This can be overcome using Microsoft compiled HTML, WebHelp or other formats.)
From a structural perspective, many similarities exist between HTML help and a website (and therefore, HTML help is sometimes called 'web help' or 'web-based help'). However, typically they have different purposes.
