Problem med blogg..

Försöker hjälpa en polare, men jag märkte rätt snabbt att jag är helt lost på det här.

Här är koden.. Jag vill få headern i centrerad :)!

Utan resultat :/

Jag gjorde väl det på slutet?

Kan du vara väldigt snäll då att ändra det som skall ändras åt mig så att jag förstår?

#header {position:relative; height:180px;background:#333 url(http://www.sweclockers.com/imagebank...MG_1241001.jpg) center top;width:50%; margin:0 auto;}

Nu förstod jag vad du menade, tackar så mycket! Vart ju riktigt bra!

EDIT: Dock hittar jag ingenstans att ändra bakgrunden för själv "bakgrunden" på hela bloggen, endast för div. wrappers.

body {background: #eee url() repeat-x left top; color: #333;
font: 12px Arial, verdana,tahoma, Helvetica, Sans-Serif; height: 100%; line-height:160%;}

Ah, det var det jag misstänkte. Dock hade jag endast repeat på x axeln och därmed så trodde jag det blev lite fel, så ändrade till repeat och då fungerade det finemang!
