noInvalidDirectionInLinearGradient

Diagnostic Category: lint/correctness/noInvalidDirectionInLinearGradient

Since: v1.9.9

Same as: stylelint/function-linear-gradient-no-nonstandard-direction

Description

Disallow non-standard direction values for linear gradient functions.

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A common mistake (matching outdated non-standard syntax) is to use just a side-or-corner without the preceding to.

Examples

Invalid

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