Files used
The following files were used in this example:
● api.css: The Cascading Style Sheet which includes the formatting specifications of the
user page. The use is optional but can simplify the design of the user page.
● index.html: The user page in the figure shown above.
● api.js: Example of using the Web API in JavaScript
● Wind_turbine.jpg: The background image displayed on the user page. The use of images
is optional. User-defined pages with many images require a lot of space in the load
memory.
