URL Regex Walkthrough

One of the biggest challenges of programming with web interfaces and various web applications is consistently parsing through URLs.

It can often be incredibly difficult and messy to find certain pieces of a URL, or even just simply determining if a user input is a URL to begin with.

Thankfully most general purpose programming languages these days have built in or third party libraries that allow usage of matchers called Regular Expressions (often called "regex" or "regexp"). These handy character sequences allow developers to easily detect and parse through strings fitting a particular pattern.

Summary

In this gist, I'll be breaking down one to help with URLs:

A Quick Forword On This Gist

This gist is for people who are willing to learn some basic skills regarding Cascading Style Sheets to create their own custom CSS for the MHGHApp.

In it we will have a quick overview of what CSS looks like, how to properly write it, and some examples of how you can apply it to the MHGHApp layout.

I know what some of you are thinking: "... But wait... Isn't this supposed to be a cheatsheet?"
