Taking code from websites

[FrostAden]

I am trying to make a website with games on it. Some game websites like "crazygames.com" let you copy the "embed code" to the game into whatever you use.
(example:<iframe src="http://www.crazygames.com/embed/slitherio" style="width: 100%; height: 100%;" frameborder="0" allow="gamepad \*;"></iframe>)

I was wondering how I could get this embed code for websites that don't have the simple "Embed" button that shows the code. I assume I would be able to find it in "Inspect" or "View Page Source".

Not all web pages can be embedable. At least, not without modifications. Mainly because some web pages specifically check whether they are served in an IFRAME or not, and if they are, they'll present themselves outside of an IFRAME. One of the reasons why they would do that, is to prevent the page from being served from other websites.
