Semantic elements include using a tag with emp instead of i for creating italics. This allows italics to be coded using CSS allowing emphasis to be shown elsewhere. Semantic markup also neatly organizes your code. By adding header or main tag elements before coding, it allows the viewer to easily know and understand ehat it is they are looking at.
