HTML Block Level Tags
HTML
Block element always occupies the whole horizontal space of its parent element.
HTML Block level Tags
Block elements stack vertically and take up as much horizontal space as possible.
Block elements force the text to start with a new line.
One Block level element can be placed in a row by default, but using css we can put multiple block elements in a single line.
Block-level elements may contain other block-level elements or inline elements.
