CSS agtergrond Eiendom


Voorbeeld

Stel verskillende agtergrondeienskappe in een verklaring:

body {
  background: lightblue url("img_tree.gif") no-repeat fixed center;
}

Definisie en gebruik

Die backgroundeiendom is 'n snelskrif eiendom vir:

Dit maak nie saak of een van die waardes hierbo ontbreek nie, bv. agtergrond:#ff0000 url(smiley.gif); word toegelaat.

Standaard waarde: sien individuele eiendomme
Geërf: geen
Animateerbaar: ja, sien individuele eiendomme . Lees oor animeerbaar
Weergawe: CSS1 + nuwe eiendomme in CSS3
JavaScript-sintaksis: object .style.background="rooi url(smiley.gif) links bo geen herhaling"

Blaaierondersteuning

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

Property
background 1.0 4.0 1.0 1.0 3.5

Let wel: Sien individuele blaaierondersteuning vir elke waarde hieronder.



CSS-sintaksis

background: bg-color bg-image position/bg-size bg-repeat bg-origin bg-clip bg-attachment initial|inherit;

Let wel: As een van die eienskappe in die snelskrifverklaring die bg-grootte-eienskap is, moet jy 'n / (skuinsstreep) gebruik om dit van die bg-posisie-eienskap te skei, bv. background:url(smiley.gif) 10px 20px/50px 50px ; sal lei tot 'n agtergrondprent, geposisioneer 10 pixels van links, 20 pixels van bo af, en die grootte van die prent sal 50 pixels breed en 50 pixels hoog wees.

Let wel: As u veelvuldige agtergrondprentbronne gebruik, maar ook 'n agtergrondkleur wil hê, moet die agtergrondkleurparameter laaste in die lys wees.
