CSS 필터 속성
예시
모든 이미지를 흑백(100% 회색)으로 변경:
img {
filter: grayscale(100%);
}
팁: 아래에서 더 많은 "직접 사용해 보기" 예제를 참조하세요.
정의 및 사용
filter속성은 요소(종종 <img>)에 대한 시각 효과(예: 흐림 및 채도)를 정의합니다 .
브라우저 지원
표의 숫자는 속성을 완전히 지원하는 첫 번째 브라우저 버전을 지정합니다.
-webkit- 뒤에 오는 숫자는 접두사와 함께 작동한 첫 번째 버전을 지정합니다.
| Property | |||||
|---|---|---|---|---|---|
| filter | 53.0 18.0 -webkit- |
13.0 | 35.0 | 9.1 6.0 -webkit- |
40.0 15.0 -webkit- |
CSS 구문
filter: none | blur() | brightness() | contrast() | drop-shadow() | grayscale() | hue-rotate() | invert() | opacity() | saturate() | sepia() | url();
팁: 여러 필터를 사용하려면 각 필터를 공백으로 구분하십시오(아래 "추가 예" 참조).
필터 기능
참고: 백분율 값(예: 75%)을 사용하는 필터는 값을 소수(예: 0.75)로도 허용합니다.
| Filter | Description | Play it |
|---|---|---|
| none | Default value. Specifies no effects | |
| blur(px) | Applies a blur effect to the image. A larger value will create more blur. If no value is specified, 0 is used. |
|
| brightness(%) | Adjusts the brightness of the image. 0% will make the image completely black. 100% (1) is default and represents the original image. Values over 100% will provide brighter results. |
|
| contrast(%) | Adjusts the contrast of the image. 0% will make the image completely black. 100% (1) is default, and represents the original image. Values over 100% will provide results with more contrast. |
|
| drop-shadow(h-shadow v-shadow blur spread color) | Applies a drop shadow effect to the image. Possible values: h-shadow - Required. Specifies a pixel value for the horizontal shadow. Negative values place the shadow to the left of the image. v-shadow - Required. Specifies a pixel value for the vertical shadow. Negative values place the shadow above the image. blur - Optional. This is the third value, and must be in pixels. Adds a blur effect to the shadow. A larger value will create more blur (the shadow becomes bigger and lighter). Negative values are not allowed. If no value is specified, 0 is used (the shadow's edge is sharp). spread - Optional. This is the fourth value, and must be in pixels. Positive values will cause the shadow to expand and grow bigger, and negative values will cause the shadow to shrink. If not specified, it will be 0 (the shadow will be the same size as the element). Note: Chrome, Safari and Opera, and maybe other browsers, do not support this 4th length; it will not render if added. color - Optional. Adds a color to the shadow. If not specified, the color depends on the browser (often black). An example of creating a red shadow, which is 8px big both horizontally and vertically, with a blur effect of 10px: filter: drop-shadow(8px 8px 10px red); Tip: This filter is similar to the box-shadow property. |
|
| grayscale(%) | Converts the image to grayscale. 0% (0) is default and represents the original image. 100% will make the image completely gray (used for black and white images). Note: Negative values are not allowed. |
|
| hue-rotate(deg) | Applies a hue rotation on the image. The value defines the number of degrees around the color circle the image samples will be adjusted. 0deg is default, and represents the original image. Note: Maximum value is 360deg. |
|
| invert(%) | Inverts the samples in the image. 0% (0) is default and represents the original image. 100% will make the image completely inverted. Note: Negative values are not allowed. |
|
| opacity(%) | Sets the opacity level for the image. The opacity-level describes the transparency-level, where: 0% is completely transparent. 100% (1) is default and represents the original image (no transparency). Note: Negative values are not allowed. Tip: This filter is similar to the opacity property. |
|
| saturate(%) | Saturates the image. 0% (0) will make the image completely un-saturated. 100% is default and represents the original image. Values over 100% provides super-saturated results. Note: Negative values are not allowed. |
|
| sepia(%) | Converts the image to sepia. 0% (0) is default and represents the original image. 100% will make the image completely sepia. Note: Negative values are not allowed. |
|
| url() | The url() function takes the location of an XML file that specifies an SVG filter, and may include an anchor to a specific filter element. Example: filter: url(svg-url#element-id) |
|
| initial | Sets this property to its default value. Read about initial | |
| inherit | Inherits this property from its parent element. Read about inherit |

여러 필터 사용
여러 필터를 사용하려면 각 필터를 공백으로 구분하세요. 순서가 중요합니다(예: 세피아() 다음에 grayscale()를 사용하면 완전히 회색 이미지가 생성됨).
img {
filter: contrast(200%) brightness(150%);
}
