Web Development Resources

HTML

HTML stands for Hypertext Markup Language and is how documents (web pages) are structured so that they appear a certain way in a web browser. When your web browser (Firefox / Chrome / Safari / etc...) receives an HTML document, it renders the markup into the "page" that you see.

• Introduction to HTML -- This looks like a great starter resource that shows you how basic markup is rendered in the browser. It even has a live preview so that you can try things out and see how they appear.

If your Linux distribution is so out of date that you can no longer install updated patches, you'll typically need to either reach for an unsupported package or install the software via source. Additionally, I didn't want to interfere with installed software in fear of rendering the system unusable.

Become Root and Grab Tarballs

You're going to be installing stuff that requires root access, so it's easier to just be able to do it when you want without having to worry about using sudo and permissions. Be careful you don't delete anything you can't recover
