You have probably encountered embed codes before, but they may seem like a bit of a mystery.
An embed code is, in short, a bit of HTML that allows you to embed part of another web site on your own – like a YouTube video, for example.
Embed codes come in two general flavors these days, and each has its strengths and weaknesses.
So, how do embed codes work? Why are some hugemongous, and others teeny-tiny? Are iframe tags really the spawn of the devil?
Okay, I know this one has been done like 8 bazillion times, but this method of creating a drop shadow on elements in a web page via CSS and a 1 pixel by 1 pixel transparent PNG file actually DOES work.
You see, I tried all kinds of different methods of creating drop shadows in CSS, both with and without an image file, and there was always a problem. It would render properly in certain browsers. It would render properly, but it only worked for fixed-width elements on the page. Or, maybe it would only render properly for variable width page elements. Or, the darn thing just didn’t work at all.
Well, I got tired of all of that, so I decided to make my own version of the CSS drop shadow. It may not be the prettiest, but it works.
