How do you create links to sections within the same page? Links can be created using the <a> tag, with referencing through the use of the number (#) symbol. For example, you can have one line as <a href=”#topmost”>BACK TO TOP</a>, which would result in the words “BACK TO TOP” appearing on the webpage and links to a bookmark named topmost. You then create a separate tag command like <a name=”topmost”> somewhere on the top of the same webpage so that the user will be linked to that spot when he clicked on “BACK TO TOP”.
