What do < and > stand for?
提问by Michiel Pater
I know that the entities <and >are used for <and >, but I am curious what these names stand for.
我知道实体<and>用于<and >，但我很好奇这些名称代表什么。
Does <stand for something like "Left tag" or is it just a code?
是否<代表类似“左边的标记”或者是它只是一个代码？

They're used to explicitly define less than and greater than symbols. If one wanted to type out <html>and not have it be a tag in the HTML, one would use them. An alternate way is to wrap the <code>element around code to not run into that.
它们用于显式定义小于和大于符号。如果想要输入<html>而不是将其作为 HTML 中的标签，则可以使用它们。另一种方法是将<code>元素包装在代码周围，以免遇到这种情况。
They can also be used to present mathematical operators.
它们还可用于表示数学运算符。

Why can't we simply use the <and >characters in HTML?
为什么我们不能简单地在 HTML 中使用<和>字符？
- This is because the
>and<characters are ‘reserved' characters in HTML. - HTML is a mark up language: The
<and>are used to denote the starting and ending of different attributes: e.g.<h1>and not for the displaying of the greater than or less than symbols. But what if you wanted to actually display those symbols? You would simply use<and>and the browser will know exactly how to display it.
- 这是因为
>和<字符是 HTML 中的“保留”字符。 - HTML 是一种标记语言：
<和>用于表示不同属性的开始和结束：例如，<h1>和 不用于显示大于或小于符号。但是，如果您想实际显示这些符号怎么办？您只需使用<and>，浏览器就会确切地知道如何显示它。

> and <是HTML 中>和<字符的字符实体引用。
It is not possible to use the less than (<) or greater than (>) signs in your file, because the browser will mix them with tags.
不能在文件中使用小于 (<) 或大于 (>) 符号，因为浏览器会将它们与标签混合。
for these difficulties you can use entity names(>) and entity numbers(<).
对于这些困难，您可以使用实体名称（>）和实体编号（<）。

In HTML, the less-than sign is used at the beginning of tags.
if you use this bracket "<test1>" in content, your bracket content will be unvisible, html renderer is assuming it as a html tag, changing chars with it's ASCI numbers prevents the issue.
在 HTML 中，小于号用于标签的开头。如果您<test1>在内容中使用此括号“ ”，您的括号内容将不可见，html 渲染器将其假定为 html 标签，使用它的 ASCI 数字更改字符可以防止出现此问题。
with html friendly name:
带有 html 友好名称：
<test1>
or with asci number:
或 asci 编号：
<test1>
or comple asci:
或完整的asci：
<test1>
result: <test1>
结果：<test1>
