Final answer:
True, block level elements are rendered on a new line and create a block of space, which is a key characteristic distinguishing them from inline elements. b) False.
Step-by-step explanation:
Block level elements in HTML are indeed rendered on a new line from the content they follow. This is one of the defining properties of block-level elements compared to inline elements. Block-level elements like <div>, <p>, and <h1> to <h6> typically start on a new line and stretch out as wide as their parent container, effectively creating a 'block' of space in the layout. This is contrasted with inline elements such as <span> and <a>, which do not start on a new line and only take up as much width as necessary.
