Understanding ArcGIS Online Code

Can someone point me to a good resource to better understand the code that drives ArcGIS Online's ability to embed a map and use a template so I can gain more control of the output?


For example, when I select embed in website option, I get a little paragraph of text that looks something like this:


<style>.embed-container {position: relative; padding-bottom: 80%; height: 0; max-width: 100%;} .embed-container iframe, .embed-container object, .embed-container iframe{position: absolute; top: 0; left: 0; width: 100%; height: 100%;} small{position: absolute; z-index: 40; bottom: 0; margin-bottom: -15px;}</style><div class="embed-container"><iframe width="500" height="400" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" title="Manna Food Center Distribution Sites" src="//;extent=-78.2349,38.6246,-75.5432,39.5752&amp;zoom=true&amp;scale=true&amp;disable_scroll=true&amp;theme=light"></iframe></div>

I understand the width = "500" height = "400" is the canvass size because there is an option to adjust this in the Embed Map Dialogue box. However, I would like to better understand all the other code so I can manipulate it better. Is this JavaScript?
