In CSS, you can use the font-size attribute to adjust the font size; the font-size attribute is used to set the font size. If an element does not explicitly define the font-size attribute, it will automatically inherit the calculation result of the font-size attribute of the parent element.

Note that the font-size attribute actually sets the height of the character boxes in the font; the actual character glyph may be taller or shorter than these boxes (usually shorter).

Attribute values that can be set:
