no-invalid-repeat-count

Disallow invalid fixed repeat counts in CSS Grid track templates.

The first argument to a fixed repeat() must be a positive integer. Counts such as 0, negative numbers, and decimals make the track template invalid. This rule leaves auto-fit, auto-fill, and dynamic values to the rules that own those cases.

  grid-template-columns: repeat(0, 1fr);

}
