By definition :before and :after are CSS pseudo elements. You can use them to insert something before or after the content of an element. There are some great articles giving the basics, but I wanted to write down a blog post for the real use cases. Or, at least, to show what I'm using them for.

The replace method in JavaScript is pretty much the same as in the other languages. Replace part/s of a string with something else.

Probably I'll be in the same situation after week or so and I'll just check here for the proper solution.

FlashDevelop is one of the most preferred editors for the flash development. I've been also using it last few years. I found it helpful for writing JavaScript, HTML, CSS and PHP code as well.
