Transparente iFrames
Wird das Attribut color-scheme im eingebetteten Dokument nicht korrekt gesetzt, kann der Browser einen systemseitigen Hintergrund (z. B. Weiß im Light Mode, Dunkelgrau im Dark Mode) anstelle eines transparenten Hintergrunds rendern. Um sicherzustellen, dass der iFrame-Hintergrund in allen Umgebungen wirklich transparent bleibt, muss der folgende Code-Abschnitt abhängig von der Werbeform in das jeweilige Dokument vor dem schließenden </body>-Tag eingebunden werden.
| Werbeform | Position | Code |
|---|---|---|
| Page Skin | <script>
window.addEventListener("message", (event) => {
const referrer = new URL(document.referrer).hostname;
const origin = new URL(event.origin).hostname;
if (origin !== referrer || event.data.type !== "iqdIframeTransparency") return;
if (event.data.htmlNeedsColorScheme && event.data.isFirefox) document.querySelector('html').style.colorScheme = 'dark';
});
</script>
