Ví dụ
<!DOCTYPE html> <html> <head> <style> div { width: 500px; height: 400px; background: yellow; border: 5px dashed yellow; background-image: url('https://www.tutorialspoint.com/latest/microservice_architecture.png'); animation: myanim 3s infinite; background-position: bottom left; background-size: 50px; } @keyframes myanim { 20% { background-color: maroon; background-position: bottom right; background-size: 90px; border-bottom: 25px solid orange; } } </style> </head> <body> <h2>Performing Animation for bottom border</h2> <div></div> </body> </html>
