In my CSS file I'm using custom CSS as can be seen from the photo. WebStorm gives errors. How can I fix it?

When hovered on it full error is here

Cannot resolve '--color-gray-1' custom property
This inspection warns about CSS custom property variable references which cannot be resolved to any valid target

Adding the property to custom CSS properties suppresses the 'Unknown CSS property' inspection; But in your screenshot I am guessing the warning comes from W3C validator. W3C Validator Inspection is based on external tool provided by W3C (online version available at http://jigsaw.w3.org/css-validator/#validate_by_input), so we can do nothing to fix such warnings. Plus w3C validator is not always up-to-date and reports errors for valid CSS, but some users still like to have it enabled.

You can only disable this inspection if you don't like these errors being displayed: hit Alt+Enter and choose 'Disable W3C CSS validation'.

two ways you can try：

1. :root {
     --color-gray-1: #666666;
   }

2. html, body {
     --color-gray-1: #666666;
     color: var(--color-gray-1)
   }

Make sure directory css file resides in is not excluded: right click on directory > Mark Directory As > Not Excluded
