推荐答案
By looking up the W3C Recommendations Form elements description, it clearly shows that you better not use that way.
您可以在以下位置使用Form元素:
You can use the Form element in:
可以使用此元素的上下文:流内容在哪里 预期的.
Contexts in which this element can be used: Where flow content is expected.
流内容的描述如下:
文档和应用程序主体中使用的大多数元素 被归类为流内容.
Most elements that are used in the body of documents and applications are categorized as flow content.
因此，由于不遵循这些建议，因此任何HTML验证程序也将向您报告错误，因为在正文定义中未找到打开开始标记的表单.这是完全有效的，因为:
So by not following these recommendations, any HTML validators will also report you errors, since the forms opening closing tags are not found in side the body definition. Which is perfectly valid since:
在text/html中省略标签:两个标签都不能省略.
