BEM. Not a concept of basic concepts - block, element, modifier?

Question

css

An element is an integral part of a block that cannot be used in isolation from it. (from off-dock)

.post{}
.post__date{} // может использоваться как дата в комментариях к посту
.post__header{} //может использоватся как заголовок страницы
.post__body{} //может использоватся в том же комментарии

if you think about it, then any element, any block can be reused somewhere, then this is not an element but a block. As a result, it turns out that everything can be represented as blocks and their modifiers, and the block will be empty or have minimal styles so that it can be used in other projects and parts of the vertex. It turns out that the block is purely a Namespace for other entities.

<div class="post"> 
   <div class="header header_post">Заголовок поста</div>
   <div class="date date_post">19.19.1900</div>
   <div class="body body_post">текст</div>
</div>
<div class="comment"> 
   <div class="date date_comment">19.19.1900</div>
   <div class="body body_comment">текст</div>
</div>
