The elements in the HTML document are arranged one after another. Line breaks are simply added before and after the block-level elements, which is a streamlined layout. However, the Web pages we see are laid out according to certain rules (usually multi-column), so we need to use certain methods to achieve this layout. The usual solution is: use block elements ) to lay out the content of a Web page.
Using tables for layout is an older layout solution. It is not recommended, we should always use tables to display tabulated data.
