   คณะสัตวแพทยศาสตร์ มหาวิทยาลัยมหิดล

   หมายเหตุสำคัญ:
   - Class ทั้งหมด prefix ด้วย "donation-channel-" เพื่อไม่ให้ชนกับ
     CSS เดิมของเว็บไซต์ (main.css / Site1.Master)
   - สีที่กำหนดไว้ด้านล่างเป็นค่าประมาณจากโทนสีที่ปรากฏใน
     donation.aspx เดิม (fund-area, ปุ่ม, ฯลฯ) ทีมพัฒนาควรเทียบกับ
     ตัวแปรสี/ธีมจริงใน Site1.Master และ main.css แล้วปรับค่าตัวแปร
     ในบล็อก :root ด้านล่างให้ตรงกับธีมของเว็บไซต์คณะฯ
