Public Distribution of Dreamweaver CSS Syntax Validation Definition

This is a property sheet for Dreamweaver's CSS editor to disable warnings related to custom properties and universal selectors.
I created this because the warnings are annoying.

Note: To enable custom properties, warnings for non-existent (undefined in CSS) properties will also be disabled.

For example, the following warnings (like "Expected RBRACE at line xxxxxxx") will be disabled:

:root {
    --cfw-body-font-color: #000; // ← Warning here
}

@keyframes blinking { // ← Warning here
    0% {
        opacity: 0.1;
        color: var(--cfw-theme-font-color); // ← Warning here
    }
    100% {
        opacity: 1;
        color: var(--cfw-color-red); // ← Warning here
    }
}

.ql-editor ul[data-checked=true] > li *, // ← Warning here
.ql-editor ul[data-checked=false] > li * { // ← Warning here
    pointer-events: all;
}
