# font-weight-notation
|
||
|
|
|
||
|
|
Require numeric or named (where possible) `font-weight` values. Also, when named values are expected, require only valid names.
|
||
|
|
|
||
|
|
```css
|
||
|
|
a { font-weight: bold }
|
||
|
|
/** ↑
|
||
|
|
* This notation */
|
||
|
|
|
||
|
|
a { font: italic small-caps 600 16px/3 cursive; }
|
||
|
|
/** ↑
|
||
|
|
* And this notation, too */
|
||
|
|
```
|
||
|
|
|
||
|
|
Valid font-weight names are `normal`, `bold`, `bolder`, and `lighter`.
|
||
|
|
|
||
|
|
This rule ignores `$sass`, `@less`, and `var(--custom-property)` variable syntaxes.
|
||
|
|
|
||
|
|
## Options
|
||
|
|
|
||
|
|
`string`: `"numeric"|"named-where-possible"`
|
||
|
|
|
||
|
|
### `"numeric"`
|
||
|
|
|
||
|
|
`font-weight` values *must always* be numbers.
|
||
|
|
|
||
|
|
The following patterns are considered warnings:
|
||
|
|
|
||
|
|
```css
|
||
|
|
a { font-weight: bold; }
|
||
|
|
```
|
||
|
|
|
||
|
|
```css
|
||
|
|
a { font: italic normal 20px; }
|
||
|
|
```
|
||
|
|
|
||
|
|
The following patterns are *not* considered warnings:
|
||
|
|
|
||
|
|
```css
|
||
|
|
a { font-weight: 700; }
|
||
|
|
```
|
||
|
|
|
||
|
|
```css
|
||
|
|
a { font: italic 900 20px; }
|
||
|
|
```
|
||
|
|
|
||
|
|
### `"named-where-possible"`
|
||
|
|
|
||
|
|
`font-weight` values *must always* be keywords when an appropriate keyword is available.
|
||
|
|
|
||
|
|
This means that only `400` and `700` will be rejected, because those are the only numbers with keyword equivalents (`normal` and `bold`).
|
||
|
|
|
||
|
|
The following patterns are considered warnings:
|
||
|
|
|
||
|
|
```css
|
||
|
|
a { font-weight: 700; }
|
||
|
|
```
|
||
|
|
|
||
|
|
```css
|
||
|
|
a { font: italic 400 20px; }
|
||
|
|
```
|
||
|
|
|
||
|
|
The following patterns are *not* considered warnings:
|
||
|
|
|
||
|
|
```css
|
||
|
|
a { font-weight: bold; }
|
||
|
|
```
|
||
|
|
|
||
|
|
```css
|
||
|
|
a { font: italic normal 20px; }
|
||
|
|
```
|
||
|
|
|
||
|
|
## Optional secondary options
|
||
|
|
|
||
|
|
### `ignore: ["relative"]`
|
||
|
|
|
||
|
|
Ignore the [*relative*](https://drafts.csswg.org/css-fonts/#font-weight-prop) keyword names of `bolder` and `lighter`.
|
||
|
|
|
||
|
|
The following patterns are *not* considered warnings:
|
||
|
|
|
||
|
|
```css
|
||
|
|
a { font-weight: 400; }
|
||
|
|
a b { font-weight: lighter; }
|
||
|
|
```
