The lack of standards and the crazy amount of quirks between each individual e-mail client (both web and mobile) is pretty crazy. For example, some e-mail clients completely strip the <style> and <head> tags, and support the bare-bones inline CSS styles (and not everything, at that), and other e-mail clients are slightly more technologically caught up, and have HTML standards that aren't ancient. The differences are too much between various clients, and lots of e-mail templates out there look perfect on certain clients, and then make you do a "facepalm" on others. I recently had to do a responsive e-mail template as a project, and let's just say... it was quite a trip making it work across various e-mail clients! I thought that this template here would help some people who are looking to make an HTML e-mail that works across most e-mail clients, both web based and mobile based, by providing a very simple and basic layout to get started, and working off of that. There are tons of templates out there, with tons of notes, comments, and code clamored in them, all over the place, and they fail to make it simple. This is what I am trying to do here for the community (not sure how much help it will be, but nevertheless) - just provide an HTML skeleton template, so that writing an HTML e-mail that works across multiple clients doesn't have to be such a hair-pulling, eye-gouging task. I had no idea how different and crazy the coding of an HTML e-mail would be, when compared to tradition HTML web design. If you made it here, then you are probably looking for a simple solution that doesn't fill your head with too much unnecessary info (not saying that info isn't good, just saying some of it COULD be not as vital as you need for your specific task). Well, hope this is of at least some use to someone...
