CSS3에서 이미지를 Grayscale로 변환하려면 filter 속성에 grayscale 값을 사용하세요.
예시
예를 들어 보겠습니다 -
<!DOCTYPE html>
<html>
<head>
<style>
img.demo {
filter: brightness(120%);
filter: contrast(120%);
filter: grayscale(130%);
}
</style>
</head>
<body>
<h1>Spring Framework</h1>
<img src="https://www.tutorialspoint.com/spring/images/spring-mini-logo.jpg" alt="Spring" width="160" height="150">
<h1>Learn MySQL</h1>
<p>Below image is brighter and has more contrast than the original image above. With that the image is in grayscale:</p>
<img class="demo" src="https://www.tutorialspoint.com/spring/images/spring-mini-logo.jpg" alt="Spring" width="160" height="150">
</body>
</html> 출력
