How to view the HTML code

I am trying to find the HTML code just to view and search through it, that way I can know the classes of everything so I can edit the proper things in the CSS code. 

Where can I view and search the HTML? 


Re: How to view the HTML code

There are a few things in the Theme menu (Theme > Edit HTML/CSS) under header type that will give you class names of header specific elements and few classes hither and thither about the partials folder, but I'm not sure if there is a comprehensive, full-site list of element ids/classes. In my experience I check things out via the Chrome/FireFox/IE dev tools (F12) when I need to inspect and change a certain item but I'm curious if anyone else has insight on this as well. A master list of (default) components would be nice, especially for things like social icons or buttons.
