Its sibling elements must not be on the same line as it (unless out of the document flow). In fact, in layman's terms, block elements are generally container elements for other elements and can accommodate other block elements or inline elements. The most common ones are P and div. To put it simply, the block element is like a four-square box that can hold other four squares and can be presented anywhere on the page.
