To understand this "HTML thorough analysis" of the mark classification, please see " Mark List ".
Please also understand the distinction between containment and empty tags, see "HTML concept ."

 
<!--notes: ▲top

Usage: Used to insert some comments and explanatory languages that are not displayed in the browser
Start/End Identification: must/must
Properties: No
Null: Allow
Note: Its content length does not need to be limited to one line, can be arbitrary length. End identity and start identification can not be on a single line.

Like many computer languages, HTML also provides annotation functionality. The browser ignores the text in this tag (which can be many rows) without displaying it for general purposes:

  • Add a description to the different parts of the article to facilitate future modification.
    This is especially important for more complex or private pages, not just reminding yourself of what the other colleagues are doing and what that part does.
    Example:
    <!--Starting here is the product order form-->

  • used as a copyright notice.
    If you do not want someone else to use or copy your Web page, add a warning phrase.
    Example:<!--copyright of this article, fortuneage all, without permission, do not copy-->
 
<P>: ▲top

Usage: Define a paragraph
Start/End ID: must/optional
Properties:%coreattrs,%i18n,%events
Align= "..." is opposed. Used to control alignment (left, right, center, justify)
Null: Not Allowed

<P> is called a paragraph mark . Function: Leave a blank line.

Originally <P> is a containment mark, marked at the end of a paragraph, but no </P> is required to begin with HTML 2.0.

<P> Common parameters: such as: <p align= "center" >

    • Align= "center"
      Optional value: Right, left, center.
      Default value: align= "Left"

Example:

Original code This is the text for my paragraph. It does ' t matter how long it is,
How many spaces are between the words or when I decide to hit the return key.
It'll create a new paragraph only if I begin the tag with another one.
<P> Here ' s the next paragraph.
Show results

This is the text for my paragraph. It does ' t matter how-long it is, how many spaces are between the words the "I decide to hit the" Return key. It'll create a new paragraph only if I begin the tag with another one.

<BR>: ▲top

Usage: Force One line of text to break
Start/End Identification: must/must

Clear= "..." sets the starting position of the next paragraph after a floating object (none, left, right, all)
Null: Not Allowed

<BR> is called a newline tag . Function: Make subsequent content appear on the next line.

Because the browser automatically ignores whitespace and line-wrapping parts of the original code, this makes <BR> one of the most commonly used tags. Because no matter how beautiful the article is in the original code, if you add a newline or paragraph mark inappropriately, the browser will only display it as a large segment.
