CSS treats an HTML document as a hierarchical tree of elements, where each element can have zero or more child elements arranged in an ordered way. The topmost element of this tree is called as the root element or the parent element. These elements display their content at a specific position, which is defined by using CSS properties. The box model allows placing a border around the elements and also provides space between elements.
