HTML Tutorial: Collection of commonly used HTML tags (6)

These introduced HTML tags do not necessarily fully conform to the XHTML specification. You should make some choices when making actual layout, for example: the B tag and the FONT tag are not in compliance with the XHTML specification.

These introduced HTML tags do not necessarily fully conform to the XHTML specification. You should make some choices when making actual layout, for example: the B tag and the FONT tag are not in compliance with the XHTML specification.
1. Basic TAG elements
--------------------------------------------------------------------------
File format <HTML></HTML> (beginning and end of HTML file)
Title <TITLE></TITLE> (Must be placed in the header section)
Header section <HEAD></HEAD> (description of the document, such as "subject")
Body section <BODY></BODY> (where the content is located)
2. Structural elements
--------------------------------------------------------------------------
Title <H?></H?> (There are six types: H1, H2, H3, H4, H5, H6)
Title alignment <H? ALIGN=LEFT|CENTER|RIGHT></H?>
Section <DIV></DIV>
Section alignment <DIV ALIGN=LEFT|RIGHT|CENTER></DIV>
Short quotes <Q> and </Q>
Yes for some referenced files, if the referenced part is not long. Then you can consider using this tag, which is the new syntax of HTML3.0.
Citation section
<BLOCKQUOTE></BLOCKQUOTE> (usually indented when displayed) blockquote is used to indicate that the document in the area is quoting a person or information in a document. Usually quoted text is quoted using <BLOCKQUOTE> and
</BLOCKQUOTE> to mark them. Then most browsers will represent it in another way when reading these words. This is just to remind readers that this is a quote from someone else.
Emphasis (usually in italics)
Strong emphasis (usually in bold) This character is STRONG, which is similar to
EM is just a way of strengthening the tone of speech. Most browsers use bold font to indicate words marked with and .
Citation statement <CITE></CITE> (usually in italics) Use <CITE> and </CITE> to mark the words quoted by others Program source code <CODE></CODE> If the reader is writing something about computers, then CODE
This tag marks some related words together. The way of using it is to mark the related words with <CODE> and </CODE>.
Program output sample <SAMP></SAMP> is not modified in HTML. If you want to print HTML
The syntax of . Then readers may need to use some special techniques to print these characters. Outside of these characters, readers can use SAMP
This symbol marks them. The characteristic of this tag is that the marked text will be represented by a fixed width.
Keyboard input <KBD></KBD> The KBD tag is usually used to tell the reader which words can be typed. These are marked as
KBD characters are usually represented in fixed-width bold font. But some browsers only use fixed-width characters.
Program variables <VAR></VAR> For some words that may change, HTML provides a
It is displayed with the VAR tag, which is meant for variables or words that may be easily changed. You can use <VAR> and
<VAR> to mark them. This serves to alert the user that these variables may be subject to change.
Define <DFN></DFN> (some browsers do not have this function) If the reader in HTML
The words used in it are some definitions. Then readers can consider using the DFN label. If the reader uses Mosaic browser. Then <DFN> and
The text marked by </DFN> will be shown in italics. Other browsers may not.
Author address <ADDRESS></ADDRESS>
Big font <BIG></BIG>
Small font 
Language <LANG>
If more than two languages are used in a document, <LANG> and </LANG> can be used to mark them. This is also the new syntax of HTML3.0.
Author (AU)
<AU> and </AU> do not represent general AU files. This tag is used in readers' articles. If certain authors are mentioned, they can be marked with a tag. This is also
HTML 3.0 is a tag specially designed for authors.
personal
(PERSON) In many indexing programs, the program sometimes displays some information pages, and when displaying these information pages. If any individual names are mentioned. Then you can use
<PERSON> and </PERSON> to mark these names. This syntax is also a new syntax added in HTML 3.0.
A word composed of several words (ACRONYM)
In English, some words are composed of several words. If you encounter this kind of word, you can consider using <ACRONYM> and
The </ACRONYM> tags enclose them in special brackets. Although this is a new syntax in HTML3.0. But for those of us who use Chinese, such a grammar is not very helpful.
Abbreviation (ABBREV) Like ACRONYM, there are many abbreviations in English. HTML 3.0
A new tag is also specially created for these abbreviations. This new tag is called <ABBREV> and of course it also has an ending symbol called </ABBREV>.
Insert (INS) In HTML files, if you want to insert a word into an existing file, you can consider using <INS> and
</INS> to mark these words. This will make it easier for readers to know whether the document has been revised when they check it. Of course, this syntax is also HTML 3.0
New syntax added in .
The syntax of delete (DEL) is used to tell the reader that certain words or some parts related to deletion are going to be deleted. This new tag also appeared in HTML3.0.

Line break (You can break the line here if necessary)
6. List element <list>
--------------------------------------------------------------------------
Unordered list <UL><LI></UL>
UL COMPACT
Header symbol type <UL TYPE=DISC|CIRCLE|SQUARE> (for all enumeration items)
<LI TYPE=DISC|CIRCLE|SQUARE> (this item and the following items)
Ordered List<OL><LI></OL>
COMPACT
Numeric type <OL TYPE=A|a|I|i|1> (for all enumeration items)
<LI TYPE=A|a|I|i|1> (this item and the following items)
Starting number <OL START=?> (for all enumeration items)
<LI VALUE=?> (this item and the following items)

--------------------------------------------------------------------------
Special characters &#?; (? is ISO 8859-1 code)
< <
> >
& &

Non-Breaking Space
9. Mathematical equations
--------------------------------------------------------------------------
Example 1:
<math>
H(s)=∫0∞
esth(t)dt
</math>
Example 2:
<math>
C<box>dVout
<over>dt</box>=Ib
&tanh;(<box>κ(Vin
-Vout)<over>2</box>
CdVoutdt=Ib &tanh;(κ(Vin-Vout)2
Example 3:
<math>
(<array align="C"><item>
&ldet;<array align="cc">
<item>x11
<item>x12
<item>x21
<item>x22
<array><rd>&rdet;
<item>y<item>z
</array>)</math> ,
From these three examples we can see:
We use &int to represent the "integral symbol", to represent a subscript, and to represent a superscript;
<box> is used to indicate that the following items will be considered as a group; <over> represents a division sign. <array> to process the matrix symbol, <array
align=C|L|R> Position of table items in center, left, or right. Items are indicated by adding <item> in front of the data. &Ldet represents the left side of the determinant, and &Rdet represents the right side of the determinant.

> (right angle bracket, greater than sign) >
