In this file is where you place some CSS rules to set some margins, padding, and some color. The index.html file references a stylesheet named site.css. Listing 1: Create an HTML page to display the geolocation coordinate information. After creating your Web project and the index.html page, open the index.html file and add the code shown in Listing 1 into this file.
