Safari Add to Home Screen Question

[gavroche]

I just recently learned about the ability to add a website icon to my phone.... by loading a site, and selecting the Add to Home Screen option.
My question: for Macrumors, it uses a great icon, and when you click the icon it launches as if it's an app.... and it has no bars for safari at top and bottom.... and you can close it like a normal app. But other sites don't do this. It creates an icon, but clicking that icon opens the site within Safari. Can anyone explain how a site like Macrumors does this and others don't....?
Thanks!

I use that so rarely I didn't even realize there were differences like that.

Websites can add a line of code to the header of the site so it acts like an standalone app when it's added to the homepage.

It's site specific. This is another reason why I primarily use MacRumors.
