View Source
From Wiki @ Karl Jones dot com
View Source is a feature in many web browsers which displays the source code for a particular web page which the browser is displaying.
Inspect Element
View Source is related to, but different from, Inspect Element.
View Source shows the source code which the browser loaded, exactly as the browser loaded it.
Inspect Element shows the Document Object Model (DOM).
The DOM is the browser's internal model of the source code.
The browser constructs the DOM upon loading the web page.
The DOM can be modified using JavaScript. See:
