Name	Values	Description	Support
`font`	`[ [ <"font-style"> \|\| <"font-variant"> \|\| <"font-weight"> ]? <"font-size"> [ / <"line-height"> ]? <"font-family"> ] \| caption \| icon \| menu \| message-box \| small-caption \| status-bar \| inherit`	This property is the shorthand format for setting font properties at the same place in the style sheet.	Yes
`font-size`	`<absolute-size> \| <relative-size> \| <length> \| <percentage> \| inherit`	This property indicates the desired height of glyphs from the font. For scalable fonts, the font-size is a scale factor applied to the `em` unit of the font. (Note that certain glyphs may bleed outside their `em` box.) For non-scalable fonts, the font-size is converted into absolute units and matched against the declared font-size of the font, using the same absolute coordinate space for both of the matched values.	Yes
`font-size-adjust`	`<number> \| none \| inherit`	This property is a way to preserve the readability of text when font fallback occurs. It does this by adjusting the font-size so that the x-height is the same regardless of the font used.	No
`font-variant`	`normal \| small-caps \| inherit`	In a small-caps font, the glyphs for lowercase letters look similar to the uppercase ones, but in a smaller size and with slightly different proportions. The "`font-variant`" property requests such a font for bicameral (having two cases, as with Latin script).	Yes

Name	Values	Description	Support
`font-family`	`<family-name>`	This property descriptor defines the font family name that will be used in all CSS font family name matching, overriding font family names contained in the underlying font data.	Yes
`font-stretch`	`normal \| ultra-condensed \| extra-condensed \| condensed \| semi-condensed \| semi-expanded \| expanded \| extra-expanded \| ultra-expanded`	This property descriptor is used to expand or contract (condense) the horizontal width of the font. The change is relative to the normal width of the font as displayed by the browser.	No
`font-style`	`normal \| italic \| oblique`	This property descriptor defines if your font will be italic, oblique, or not (the default is normal).	Yes
`font-weight`	`normal \| bold \| 100 \| 200 \| 300 \| 400 \| 500 \| 600 \| 700 \| 800 \| 900`	This property descriptor allows control of the weight (thickness) of a font.	Yes

Name	Values	Description	Support
`unicode-range`	`<urange> [, <urange>]*`	This character range descriptor defines the range of Unicode characters supported by a given font. The values of `<urange>` are expressed using hexadecimal numbers prefixed by "`U+`", corresponding to Unicode character code points. The unicode-range descriptor serves as a hint for user agents when deciding whether or not to download a font resource.	No

Name	Values	Description	Support
`src`	`[ <uri> [format(<string> [, <string>])] \| <font-face-name> ] [, <uri> [format(<string> [, <string>])] \| <font-face-name> ]*`	This font reference descriptor specifies the resource containing font data. It is required, whether the font is downloadable or locally installed.	Yes

Name	Values	Description	Support
`@font-face`	`<font-description>`	The CSS `@font-face` rule is used to hold a set of font descriptions, and allows linking to fonts that are automatically activated when needed.	Yes
