CSS -Filter- Eigenschaft


Beispiel

Ändern Sie alle Bilder in Schwarzweiß (100 % Grau):

img {
  filter: grayscale(100%);
}

Tipp: Weitere "Try it Yourself"-Beispiele unten.


Definition und Verwendung

Die filterEigenschaft definiert visuelle Effekte (wie Unschärfe und Sättigung) für ein Element (häufig <img>).

Standardwert: keiner
Vererbt: Nein
Animierbar: ja. Lesen Sie mehr über animierbare
Ausführung: CSS3
JavaScript-Syntax: Objekt .style.filter="Grayscale(100%)"

Browser-Unterstützung

Die Zahlen in der Tabelle geben die erste Browserversion an, die die Eigenschaft vollständig unterstützt.

Zahlen gefolgt von -webkit- geben die erste Version an, die mit einem Präfix funktioniert hat.

Property
filter 53.0
18.0 -webkit-
13.0 35.0 9.1
6.0 -webkit-

CSS-Syntax

filter: none | blur() | brightness() | contrast() | drop-shadow() | grayscale() | hue-rotate() | invert() | opacity() | saturate() | sepia() | url();

Tipp: Um mehrere Filter zu verwenden, trennen Sie jeden Filter durch ein Leerzeichen (siehe „Weitere Beispiele“ unten).


Filterfunktionen

Hinweis: Die Filter, die Prozentwerte verwenden (z. B. 75 %), akzeptieren den Wert auch als Dezimalzahl (z. B. 0,75).

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

Beispiel für Unschärfe

Wenden Sie einen Unschärfeeffekt auf das Bild an:

img {
  filter: blur(5px);
}

Unschärfe Beispiel 2

Wenden Sie ein unscharfes Hintergrundbild an:

img.background {
  filter: blur(35px);
}

Helligkeit Beispiel

Passen Sie die Helligkeit des Bildes an:

img {
  filter: brightness(200%);
}

Kontrastbeispiel

Passen Sie den Kontrast des Bildes an:

img {
  filter: contrast(200%);
}

Beispiel Schlagschatten

Wenden Sie einen Schlagschatteneffekt auf das Bild an:

img {
  filter: drop-shadow(8px 8px 10px gray);
}

Beispiel für Graustufen

Konvertieren Sie das Bild in Graustufen:

img {
  filter: grayscale(50%);
}

Beispiel für die Farbtonrotation

Wenden Sie eine Farbtonrotation auf das Bild an:

img {
  filter: hue-rotate(90deg);
}

Beispiel umkehren

Kehren Sie die Beispiele im Bild um:

img {
  filter: invert(100%);
}

Beispiel für Deckkraft

Legen Sie die Deckkraft für das Bild fest:

img {
  filter: opacity(30%);
}

Beispiel sättigen

Bild sättigen:

img {
  filter: saturate(800%);
}

Sepia-Beispiel

Wandeln Sie das Bild in Sepia um:

img {
  filter: sepia(100%);
}

Verwenden mehrerer Filter

Um mehrere Filter zu verwenden, trennen Sie jeden Filter durch ein Leerzeichen. Beachten Sie, dass die Reihenfolge wichtig ist (d. h. die Verwendung von grayscale() nach sepia() führt zu einem vollständig grauen Bild):

img {
  filter: contrast(200%) brightness(150%);
}

Alle Filter

Eine Demonstration aller Filterfunktionen:

.blur {
  filter: blur(4px);
}

.brightness {
  filter: brightness(0.30);
}

.contrast {
  filter: contrast(180%);
}

.grayscale {
  filter: grayscale(100%);
}

.huerotate {
  filter: hue-rotate(180deg);
}

.invert {
  filter: invert(100%);
}

.opacity {
  filter: opacity(50%);
}

.saturate {
  filter: saturate(7);
}

.sepia {
  filter: sepia(100%);
}

.shadow {
  filter: drop-shadow(8px 8px 10px green);
