Add the information you want to show at the top of all your pages. Name the page/file xheader.htm and save it in text format.
NOTE: there will be 2 pages created - one is for your header and the other is for your footer. You will refer to them on your webpages with a simple code, that puts them online for you. Have you ever printed on to stationary before? Well, that's what headers are footers are similiar to, except you don't have to provide spacing for it on your page. Another thing to remember is that xheader.htm and xfooter.htm do NOT have < body > or < html > on the page. Those are strictly for your webpage.
The code to use is below. Add this code immediately after the < body> code of your page. You will do the exact same for a footer only make the file's name be xfooter.htm and the code as well. The footer code goes immediately above the < /body> tag.
<!--#include virtual="xheader-test.htm"-->
The code must be in this format, spacing, dashes, etc.
You will not see the xheader/xfooter information on your computer. It will only display after you have uploaded the page which contains the code.
