The line break tag <br> is used for creating a break element in an HTML document. The <br> element is classified as a “void element” since it has no content. This also means that there is no end tag.
换行标签<br> i用于在HTML文档中创建换行元素。<br> 元素被归类为“无效元素”，因为它没有内容。这也意味着没有结束标签。
Note: The line break tag <br> should only be used for line breaks that are actually part of the content, such as a line break in a poem or address. It should not be used for separating thematic groups in a string of text. Thematic groups should be separated by using multiple paragraph tags <p>.
注意：换行标记<br> 只应用于实际上是内容一部分的换行符，例如诗歌或地址中的换行符。它不应用于在一串文本中分隔主题组。主题组应使用多个段落标记<p>分隔。
Syntax 语法:
The line break tag is written as <br> at the point where the line break should occur. The line break is a singular element, and does not have different open and close variations like most other tags.
换行标签在应该发生换行的位置写入<br>。换行符是一个单数元素，不像大多数其他标签那样具有不同的打开和关闭变化。
