in presenting a text document (html) what is the best part and critical part?
Sorry, but I have absolutely no idea what you’re talking about. I have never heard of “best part” or “critical part” in the context of HTML. Please rephrase your question or post an example if that might help me to understand.
I’m also unclear what you’re asking here, @prolifichrconsultanc.
Are you asking which part of a web page we consider to be the most important?
In terms of the HTML, it’s all important. The HTML is what defines the structure of the page, so that it can be understood by search engines, screen readers and others.
The whole document.
The html, head, and body tags.
If I take your question literally (I tend to so at the first read anyway). 
You have a text document in a html file format. The file contains tree parts:
– The html code; head and body and paragraph elements needed for an html reader/browser to present the content in a readable way.
– Then there is the content itself that can be divided and styled in different sections.
– Further, if you wish to present the text in a suitable style, you could add some CSS code to shape the content.
So, to answer your question literally:
The html tags are “critical parts” because they presents the content in a way that makes sense to the human reader. That is the purpose of the html.
The text content part is a “critical part” because that is what holds the information. Any html reader/browser can show raw unformatted text.
The “best part”, visually, would be the added CSS that styles the document to make the presentation suitable to the information it holds.
tl;dr
As others already told you; All parts of an html document are critical, if you like, as they all works together in presenting the information.
