style.css werkt niet goed

mijn probleem is dat de achtergrond niet opnieuw begint
style.css:

body {
    background-image: url(images/bg.gif);
    background-repeat: repeat-x;
    background-position: ;
    background-color: #ffffff;
    margin: auto;
    padding: 0px;
    font-family: Verdana, Arial, Helvetica, sans-serif;
    font-size: 10px;
    line-height: 150%;
    text-align: center;
    }
    
a {
    color: #5aadc6;
    text-decoration: none;
    }
    
a.hover {
    color: #ffffff;
    text-decoration: underline;
    }
    
#header_news a {
    color: #ffffff;
    text-decoration: none;
    }
    
#header_news a:hover {
    color: #ffffff;
    text-decoration: underline;
    }

Niet opnieuw begint?
Welke achtergrond?

body {
    background-image: url(images/bg.gif);
    background-repeat: repeat;

misschien die repeat-x vervangen door gewoon repeat, zoals hierboven?

Dan kan je de hele regel weghalen.

als je background-position: ; doet
kan je die beter weghalen of iets invullen.

doe dan gewoon

background: #FFF url(blaat.gif) repeat-x;

Veel makkelijker

werkt!
