Every HTML document should start with this basic outline:
<html> <head> <title>This appears at the top</title> </head> <body> The content of the page should go here </body> </html>
Named anchors are a way of jumping to specific locations within a large HTML page. The point to jump TO is marked with an anchor like this:
<a name="anchorname">
You can refer to this particular location by using the usual URL for the file along with #anchorname:
<a href="thisfile.html#anchorname"> this text would
take me to the location anchorname in the file thisfile.html
</a>

protocol://webservername.domain[port]/subdirectory(s)/filename.html

On the server files are organized by subdirectories separated by /'s. For small web pages keep everything in one subdirectory and use relative links. For larger projects you may want to use subdirectories. Remember, no spaces in filenames. Use underscores instead.
