That maybe but it differs from what is shown in the inspector (which shows the <head> and <body> tags). This could be confusing as the source html doesn't match how the browser interprets it.

Web inspectors are showing a representation of the DOM, they are not showing the raw source. Netscape and IE used to have "Show Source" functions that literally showed just the page source.

Inspectors will do things like display colors as their RGB triples i.e. rgb(x, y, z) in computed styles when a color has been defined in the HTML like in a body tag or table cell's bgcolor attribute.

All browsers still have show source. It's just not usually that useful anymore.

Yes I am aware. It can be confusing if you are new. I had someone ask me why it was different the other day.

I usually look at the network log for that information now.

Just because it is valid does not mean you should do it.

That's true. The reasons to do it are in the article.

TIL!
