CSS font Property
The font property is a shorthand property for the following properties:
font-style
font-variant
font-weight
font-size
line-height
font-family
You can set all the properties with the following order: 1. font-style, 2. font-variant, 3. font-weight, 4. font-size / line-height, 5. font-family. The line-height property is used for setting the space between lines.
It is required to define font-size and font-family properties’ values. If one of the values is missed, its default value is used.
All the individual values of the font-size property that are not specified, will be set to their initial value.

Font as a shorthand property
Font as a shorthand property
While using this shorthand property you should know some important things about it:
Mandatory values
The “font-size” and “font-family” values are considered to be mandatory ones. The whole declaration will be ignored if one of these values are absent.
Optional values
The other five values are optional. In case of using one of these values, take into account that they must come before the “font-size” value in the declaration, otherwise they will be ignored.
The font and font-stretch properties
The font-stretch property is new in CSS3, and if you use it in an older browser, the whole line will be ignored.
The inheritance for optional values
If you omit the optional values they will not inherit values from their parent element. They will be restored to their initial state.
Keywords that define system fonts
Keywords that define system fonts
The following values of the font property can be used as keywords:
caption
icon
menu
message-box
small-caption
status-bar
They set the font to the one that is used on the operating system of the user for that specific category. For example, if you specify the “menu” value, the font will be set on that element for using the same font that is used on the operating system for dropdown menus and menu lists.
These keyword-values can only be used with the font shorthand property.
