Description

Disallow non-standard directions in linear gradients.

A gradient direction must be either an angle with a unit, such as 45deg, or a side or corner preceded by to, such as to top or to bottom right. Writing only top or a unitless number uses invalid or outdated syntax.

Examples

Invalid

1
.foo { background: linear-gradient(top, #fff, #000); }

code-block.css:1:36 lint/correctness/noInvalidDirectionInLinearGradient ━━━━━━━━━━━━━━━━━━━━━━━━━━━━

  ✖ Unexpected nonstandard direction

      │                                    ^^^

  ℹ You should fix the direction value to follow the syntax.
