Definitions and usages

HTML5 defines the title by the label. D efine the largest title. Define the smallest title.

Because the h element has exact semantics, choose the appropriate label hierarchy carefully to structure your document. T herefore, do not use the title label to change the font size in the same line. Instead, we should use the Cascade Style Sheet definition to achieve a nice display.
