Some HTML editors may modify or even remove some of the HTML tags that you insert without any warning. Always verify that all the tags you've inserted appear on your web page after publishing or uploading your pages to the web site. To view HTML tags of an uploaded page, first view the page in question using your favorite web browser. Then select "View | Source" (or "View | Document Source" or similar) menu item. If you do not see these items in the main menu, try right clicking on the web page. This should bring up the HTML code for that particular page, so that you can check to make sure the custom tags you've entered remin as-is.
