CSS - hard: External Style Sheets
We are now going to look at creating external style sheets. Unfortunately, this means the fun has come to an end, as we can no longer use the in-house HTML editor that I've provided with the website. We must now turn to a text editor and local file system to continue our development.
If you are using Windows then I recommend downloading the latest version of Notepad++. You can grab it here.
If you are using a Mac then I suggest downloading the latest version of an editor called Brackets. You can grab it here.
Next we are going to have to turn to out local file system to continue development.
