CSS agtergrond-beeld eiendom


Voorbeeld

Stel 'n agtergrondprent vir die <body>-element:

body {
 background-image: url("paper.gif");
 background-color: #cccccc;
}

Voorbeeld

Stel twee agtergrondprente vir die <body>-element:

body {
  background-image: url("img_tree.gif"), url("paper.gif");
  background-color: #cccccc;
}

Meer "Probeer dit self" voorbeelde hieronder.


Definisie en gebruik

Die background-imageeiendom stel een of meer agtergrondprente vir 'n element.

By verstek word 'n agtergrondprent in die boonste linkerhoek van 'n element geplaas en beide vertikaal en horisontaal herhaal.

Wenk: Die agtergrond van 'n element is die totale grootte van die element, insluitend vulling en rand (maar nie die kantlyn nie).

Wenk: Stel altyd 'n agtergrondkleur in wat gebruik moet word as die prent nie beskikbaar is nie.

Standaard waarde: geen
Geërf: geen
Animateerbaar: geen. Lees oor animeerbaar
Weergawe: CSS1 + nuwe waardes in CSS3
JavaScript-sintaksis: voorwerp .style.backgroundImage="url(img_tree.gif)"

Blaaierondersteuning

Die nommers in die tabel spesifiseer die eerste blaaierweergawe wat die eiendom ten volle ondersteun.

Property
background-image 1.0 4.0 1.0 1.0 3.5

Let wel: IE8 en vroeër ondersteun nie veelvuldige agtergrondprente nie.



CSS-sintaksis

background-image: url|none|initial|inherit;

Eiendomswaardes

Value Description
url('URL') The URL to the image. To specify more than one image, separate the URLs with a comma
none No background image will be displayed. This is default
conic-gradient() Sets a conic gradient as the background image. Define at least two colors
linear-gradient() Sets a linear gradient as the background image. Define at least two colors (top to bottom)
radial-gradient() Sets a radial gradient as the background image. Define at least two colors (center to edges)
repeating-conic-gradient() Repeats a conic gradient
repeating-linear-gradient() Repeats a linear gradient
repeating-radial-gradient() Repeats a radial gradient
initial Sets this property to its default value. Read about initial
inherit Inherits this property from its parent element. Read about inherit

Meer voorbeelde

Voorbeeld

Stel twee agtergrondprente vir die <body>-element. Laat die eerste prent slegs een keer verskyn (met geen herhaling), en laat die tweede prent herhaal word:

body {
  background-image: url("img_tree.gif"), url("paper.gif");
  background-repeat: no-repeat, repeat;
  background-color: #cccccc;
}

Voorbeeld

Gebruik verskillende agtergrondeienskappe om 'n "held"-beeld te skep:

.hero-image {
  background-image: url("photographer.jpg"); /* The image used */
  background-color: #cccccc; /* Used if the image is unavailable */
  height: 500px; /* You must set a specified height */
  background-position: center; /* Center the image */
  background-repeat: no-repeat; /* Do not repeat the image */
  background-size: cover; /* Resize the background image to cover the entire container */
}

Voorbeeld

Stel 'n lineêre gradiënt (twee kleure) as 'n agtergrondprent vir 'n <div>-element:

#grad1 {
  height: 200px;
  background-color: #cccccc;
  background-image: linear-gradient(red, yellow);
}

Voorbeeld

Stel 'n lineêre gradiënt (drie kleure) as 'n agtergrondprent vir 'n <div>-element:

#grad1 {
  height: 200px;
  background-color: #cccccc;
  background-image: linear-gradient(red, yellow, green);
}

Voorbeeld

Die repeating-linear-gradient() funksie word gebruik om lineêre gradiënte te herhaal:

#grad1 {
  height: 200px;
  background-color: #cccccc;
  background-image: repeating-linear-gradient(red, yellow 10%, green 20%);
}

Voorbeeld

Stel 'n radiale-gradiënt (twee kleure) as 'n agtergrondprent vir 'n <div>-element:

#grad1 {
  height: 200px;
  background-color: #cccccc;
  background-image: radial-gradient(red, yellow);
}

Voorbeeld

Stel 'n radiale-gradiënt (drie kleure) as 'n agtergrondprent vir 'n <div>-element:

#grad1 {
  height: 200px;
  background-color: #cccccc;
  background-image: radial-gradient(red, yellow, green);
}

Voorbeeld

Die repeating-radial-gradient() funksie word gebruik om radiale gradiënte te herhaal:

#grad1 {
  height: 200px;
  background-color: #cccccc;
  background-image: repeating-radial-gradient(red, yellow 10%, green 20%);
}
