   1 # function-linear-gradient-no-nonstandard-direction
   2
   3 Disallow direction values in `linear-gradient()` calls that are not valid according to the
   4 [standard syntax](https://developer.mozilla.org/en-US/docs/Web/CSS/linear-gradient#Syntax).
   5
   6 ```css
   7 .foo { background: linear-gradient(to top, #fff, #000); }
   8 /**                                ↑
   9  * This (optional) first argument is the "direction" */
  10 ```
  11
  12 A valid and standard direction value is one of the following:
  13
  14 -   an angle
  15 -   `to ` plus a side-or-corner (`to top`, `to bottom`, `to left`, `to right`; `to top right`, `to right top`, `to bottom left`, etc.)
  16
  17 A common mistake (matching outdated non-standard syntax) is to use just a side-or-corner without the preceding `to`.

  19 ## Options

  21 ### `true`

  23 The following patterns are considered violations:
  24
  25 ```css
  26 .foo { background: linear-gradient(top, #fff, #000); }
  27 ```
  28
  29 ```css
  30 .foo { background: linear-gradient(bottom, #fff, #000); }
  31 ```
  32
  33 ```css
  34 .foo { background: linear-gradient(left, #fff, #000); }
  35 ```
  36
  37 ```css
  38 .foo { background: linear-gradient(45, #fff, #000); }
  39 ```
  40
  41 ```css
  42 .foo { background: linear-gradient(to top top, #fff, #000); }
  43 ```
  44
  45 The following patterns are *not* considered violations:
  46
  47 ```css
  48 .foo { background: linear-gradient(to top, #fff, #000); }
  49 ```
  50
  51 ```css
  52 .foo { background: linear-gradient(to bottom right, #fff, #000); }
  53 ```
  54
  55 ```css
  56 .foo { background: linear-gradient(45deg, #fff, #000); }
  57 ```
  58
  59 ```css
  60 .foo { background: linear-gradient(1.57rad, #fff, #000); }
  61 ```
  62
  63 ```css
  64 /* Direction defaults to "to bottom" */
  65 .foo { background: linear-gradient(#fff, #000); }
  66 ```
