Escape tags in html
提问by
What are escape tags in html?
html中的转义标签是什么？
Are they "<>to represent "<>?
And how do these work?
Is that hex, or what is it?
How is it made, and why aren't they just the characters themselves?
他们"<>要代表"<>吗？
这些是如何工作的？
那是十六进制，还是什么？
它是如何制作的，为什么它们不只是角色本身？

Here are some common entities. You do not need to use the full code - there are common aliases for frequently used entities. For example, you can use < and > to indicate less than and greater than symbols. & is ampersand, etc.
下面是一些常见的实体。您不需要使用完整代码 - 常用实体有通用别名。例如，您可以使用 < 和 > 来表示小于和大于符号。& 是＆符号等。
EDIT: That should be - < > and &
编辑：那应该是- < > and &
EDIT: Another common character is  which is often used to represent tabs in <code>segments
编辑：另一个常见字符 通常用于表示<code>段中的制表符

How do these work?
这些是如何工作的？
Anything &#num;is replaced with character from ASCII table, matching that num.
任何东西&#num;都被 ASCII 表中的字符替换，匹配那个num.
Is that hex, or what is it?
那是十六进制，还是什么？
It's not hex, the number represents characters number in decimal in ASCII table. Check out ASCII table. Check Dec and HTML columns.
它不是十六进制，数字代表ASCII表中十进制的字符数。查看ASCII 表。检查 Dec 和 HTML 列。
Why aren't they just the characters themselves?
为什么他们不只是角色本身？
Look at this example:
看这个例子：
<div>Hey you can use </div> to end div tag!</div>
It would mess up the interpreter. It's a bad example, but you got the idea.
它会搞乱口译员。这是一个不好的例子，但你明白了。
Why you can't use escape characters like in programming languages?
为什么不能像在编程语言中那样使用转义字符？
I don't have exact answer to that. But html same as xml is a markup language and not programming language and answer probably lies within history of how markup languages become what they are now.
对此我没有确切的答案。但是 html 与 xml 一样是一种标记语言而不是编程语言，答案可能就在标记语言如何成为现在的样子的历史中。

No, it's not hex, it's decimal. Hex equivalent is < But one usually uses < (less-than) for < and > for > instead.
不，它不是十六进制，它是十进制。十六进制等效是 < 但是通常使用 < (小于) < 和 > 代替 >。

Here is the complete reference of html entities:
这是 html 实体的完整参考：
It is use for correct character formatting
它用于正确的字符格式
HTML has a set of special characters which browsers recognize as part of the HTML language itself. For example, browsers know that when they encounter a < character in the HTML code, they are to interpret it as a beginning of a tag. > is one of an example of reserved character. Therefore use html character to avoid any problem and for correct practice also
HTML 有一组特殊字符，浏览器将其识别为 HTML 语言本身的一部分。例如，浏览器知道当它们在 HTML 代码中遇到 < 字符时，它们会将其解释为标签的开头。> 是保留字符的示例之一。因此，使用 html 字符来避免任何问题并进行正确的练习
