newtype Percentage

The <percentage> data type. Many CSS properties can take percentage values, often to define sizes in terms of parent objects. Percentages are formed by a <number> immediately followed by the percentage sign %. There is no space between the % and the number. Specification:

1. <https://drafts.csswg.org/css-values-3/#percentages CSS Value and Units Module Level 3 (§4.3)
2. <https://www.w3.org/TR/CSS2/syndata.html#percentage-units CSS2.1 (§4.3.3)
3. <https://www.w3.org/TR/CSS1/#percentage-units CSS1 (§6.2)

newtype Number

The <number> data type. Real numbers, possibly with a fractional component. When written literally, a number is either an integer, or zero or more decimal digits followed by a dot (.) followed by one or more decimal digits and optionally an exponent composed of "e" or E and an integer. It corresponds to the <number-token> production in the CSS Syntax Module [CSS3SYN]. As with integers, the first character of a number may be immediately preceded by - or + to indicate the number’s sign. Specifications:

1. CSS Values and Units Module Level 3 (§4.2)
2. CSS2.1 (§4.3.1)
3. CSS1 (6 Units)

newtype Alphavalue
