# function-linear-gradient-no-nonstandard-direction
|
|
|
|
Disallow direction values in `linear-gradient()` calls that are not valid according to the
|
|
[standard syntax](https://developer.mozilla.org/en-US/docs/Web/CSS/linear-gradient#Syntax).
|
|
|
|
```css
|
|
.foo { background: linear-gradient(to top, #fff, #000); }
|
|
/** ↑
|
|
* This (optional) first argument is the "direction" */
|
|
```
|
|
|
|
A valid and standard direction value is one of the following:
|
|
|
|
- an angle
|
|
- `to ` plus a side-or-corner (`to top`, `to bottom`, `to left`, `to right`; `to top right`, `to right top`, `to bottom left`, etc.)
|
|
|
|
A common mistake (matching outdated non-standard syntax) is to use just a side-or-corner without the preceding `to`.
|
|
|
|
## Options
|
|
|
|
### `true`
|
|
|
|
The following patterns are considered warnings:
|
|
|
|
```css
|
|
.foo { background: linear-gradient(top, #fff, #000); }
|
|
```
|
|
|
|
```css
|
|
.foo { background: linear-gradient(bottom, #fff, #000); }
|
|
```
|
|
|
|
```css
|
|
.foo { background: linear-gradient(left, #fff, #000); }
|
|
```
|
|
|
|
```css
|
|
.foo { background: linear-gradient(45, #fff, #000); }
|
|
```
|
|
|
|
```css
|
|
.foo { background: linear-gradient(to top top, #fff, #000); }
|
|
```
|
|
|
|
The following patterns are *not* considered warnings:
|
|
|
|
```css
|
|
.foo { background: linear-gradient(to top, #fff, #000); }
|
|
```
|
|
|
|
```css
|
|
.foo { background: linear-gradient(to bottom right, #fff, #000); }
|
|
```
|
|
|
|
```css
|
|
.foo { background: linear-gradient(45deg, #fff, #000); }
|
|
```
|
|
|
|
```css
|
|
.foo { background: linear-gradient(1.57rad, #fff, #000); }
|
|
```
|
|
|
|
```css
|
|
/* Direction defaults to "to bottom" */
|
|
.foo { background: linear-gradient(#fff, #000); }
|
|
```
