CSS variables follow the standard cascade and inheritance rules, meaning they can be overridden by more specific selectors or modified within a particular scope.

:root {
    --primary-color: #3498db;
}

.header {
    --primary-color: #e74c3c; /* Overriding the global primary color */
}

h1 {
    color: var(--primary-color); /* Uses the header's primary color inside .header */
}
