ด้วยตัวทำเครื่องหมายขั้นสูง คุณสามารถใช้ HTML และ CSS ที่กำหนดเอง
เพื่อสร้างตัวทำเครื่องหมายที่ให้ผลลัพธ์ที่ชัดเจน สามารถแสดงการโต้ตอบและภาพเคลื่อนไหว
ได้ ระบบจะเพิ่มอินสแตนซ์ AdvancedMarkerElement ทั้งหมดไปยัง DOM เป็นองค์ประกอบ HTML ซึ่งเข้าถึงได้ผ่านพร็อพเพอร์ตี้ element และจัดการได้ในลักษณะเดียวกันกับองค์ประกอบ DOM อื่นๆ เนื่องจาก AdvancedMarkerElement เป็นองค์ประกอบ DOM คุณจึงนำรูปแบบ CSS ไปใช้กับตัวทำเครื่องหมายเริ่มต้นได้โดยตรง และสร้างตัวทำเครื่องหมายที่กำหนดเองใหม่ทั้งหมดโดยใช้ HTML และ CSS

ตัวอย่างต่อไปนี้แสดงการสร้างองค์ประกอบ DIV ใหม่ โดยกำหนดคลาส CSS และเนื้อหาข้อความให้กับ DIV จากนั้นส่ง DIV เป็นค่าของ AdvancedMarkerElement.content
