Usually you will create a Bookmark in a content rich web page, positioning it where you want the top of the web page to be when you refer to the content on that page.
Creating a bookmark position in a web page is achieved by placing this HTML code where you want the bookmark to position. <a name="Bookmark"></a> Bookmark can be any name enclosed in "...." you want it to be.
To refer to this position within a page, your link code will be: <a href="#Bookmark">Bookmark Link</a> Bookmark Link is the text that will appear on your page.
To refer to this position from another place append #Bookmark to your page's URL, e.g. www.pagename.html#Bookmark
Sample: On this website visit www.valuewebsites.co.nz/links.html#VWwebs This will take you to Value Websites' designed websites - a position part way down our Links page. In this position (above "Value Websites Designed or Supported Websites") we have located the code: <a name="VWwebs"></a>
You'll see that a visitor arriving at the top of the Links page can locate the bookmarked position by clicking the link VW Designed Websites at the top right of the page.
