at-rule.
let ruleList = document.styleSheets[0].cssRules; for (let rule of ruleList) { if (!rule.ownerRule) { /* rule is not imported */ } }
This snipped obtains a reference to the stylesheet associated with the @import

let ruleList = document.styleSheets[0].cssRules; for (let rule of ruleList) { if (rule.ownerRule) { checkStylesheet(rule.ownerRule.styleSheet); } }
