There are cases where Chrome simply doesn't like if your web page accesses remote information from a different protocol. And, most other remote information are sitting behind an HTTP server.
Although, later on, we will not need a web server, but for this lab, and the next few ones, you will need one.
In this class, we will be using Git (or the GitHub client) and GitHub
So install a Git client, and create an account on GitHub.
The HTML you write tells the browser on how to build a tree.
Each leaf of the node represents a box that contains text and images, and you can style these boxes (almost) however you like using CSS attributes.
CSS is used to style your pages.
When writing CSS, don't think of it as just styling your page. Think of it as a language to query the DOM, and then applying specific attributes to the queried DOM elements.
On most (if not, all) browsers, JavaScript is used for adding interactivity to your applications.
Think of JavaScript as being bolted on to the browser, with features injected into the language to modify the web page's content (more specifically, the DOM).
