From the semantic point of view, should the content in the <li> label use the <p> label? -

& Lt; ul & gt; & lt; li & gt; HiIamanitem. & lt; li & gt; AndIamanotherone. & lt; li & gt; & lt; ul & gt;

 
 
    
  
  
 Hi I am an item. 
    
  
  
 And I am another one.

In the past, I also struggled with what elements should be included, until the author of "proficient in CSS and HTML Design Patterns" proposed three terms to divide block-level elements into three categories: structured block elements, terminal block elements, and multi-object block elements.

Structured block elements and multi-target block elements allow documents to form a structure for multiple purposes, that is, they can contain content and other block-level elements.

It is a block element of a terminal. It cannot contain other block-level elements but only content.
This method is not recommended:

text
text

From the example given by the subject, the two are semantically equivalent.

A paragraph may consist of one or more sentences.

The semantics of the change itself, so sometimes

Is redundant. If there is only one p in your li, it is obviously an extra move.
I personally feel that it is a disease and cure for the obsessive-compulsive disorder that requires semantic search and passing the standard test in actual projects. Specific analysis of the specific situation, if the landlord is the case, the P tag should be redundant, but if li is used for layout, the p tag can be used in it, for example, the following layout should be normal:

Li list too! P Paragraph! First, p represents a paragraph. Throughout li, whether there are other content that needs to be "disconnected" from this sentence, if not, then you have to take the paragraph here, it is like talking nonsense. Nonsense is of course meaningless. The effect of adding a p tag to the two types is the same. If you do not need to add a p tag, do not add an object. Therefore, you do not need to use a p tag.
With the implementation of the function, you can write less code, the simpler the better.

Ps think of one sentence, read more books, and write less code. If you use p, why do you need li?
If you use li, why do you need p?
Are you confused about whether your content is a list or paragraph ?...
