Bạn có thể thử chạy đoạn mã sau để tạo các bộ lọc hình ảnh như độ mờ, độ tương phản, độ sáng bằng CSS -
Ví dụ
<!DOCTYPE html>
<html>
<head>
<style>
img {
height: auto;
float: left;
}
.contrast {
-webkit-filter: contrast(180%);
filter: contrast(180%);
}
.brightness {
-webkit-filter: brightness(250%);
filter: brightness(250%);
}
.blur {
-webkit-filter: blur(4px);
filter: blur(4px);
}
</style>
</head>
<body>
<img
src = "https://www.tutorialspoint.com/assets/videos/courses/19/images/course_19_image.png" alt = "Animation Training" width = "200" height = "200">
<img class = "contrast"
src = "https://www.tutorialspoint.com/assets/videos/courses/19/images/course_19_image.png" alt = "Animation Training" width = "200" height = "200">
<img class = "brightness"
src = "https://www.tutorialspoint.com/assets/videos/courses/19/images/course_19_image.png" alt = "Animation Training" width = "200" height = "200">
<img class="blur"
src = "https://www.tutorialspoint.com/assets/videos/courses/19/images/course_19_image.png alt = "Animation Training" width = "200" height = "200">
</body>
</html>
