This may answer your question, you can test it in this playground playground
@sfdcfox did you share all code? otherwise, how do we get the event?
contacts; renderedCallback() { this.setBackgroundImage(); } setBackgroundImage() { const divs = this.template.querySelectorAll('div'); if (divs) { this.contacts.map((contact) => { const div = Object.values(divs).filter(div => (div.getAttribute('data-id') === contact.Id))[0]; div.style.backgroundImage = `url(${contact.Offer_Image__c})`; }); } }
