Para ponerlo negro (y con las letras blancas + alguna cosilla) tienes que pegar el codigo en BIO.
Este es el mio, yo tampoco se hacerlo, pero de momento lo tengo negro:
body{ background-color:000000; background-image:url(

); background-position:Top Left; background-attachment:fixed; background-repeat:repeat; scrollbar-track-color:000000; scrollbar-face-color:000000; scrollbar-highlight-color:FFFFFF; scrollbar-base-color:FFFFFF; scrollbar-darkShadow-color:FFFFFF; scrollbar-shadow-color:FFFFFF; scrollbar-arrow-color:FFFFFF; } Table, Td{ background-color:transparent; } table table table{ width:100%; background-color:000000; border-color:FFFFFF; border-style:Dashed; border-width:2px; } table table table table{ width:auto; } table table table table, table table table td{ border-style:none; } body, div, p, strong, td, .text, .blacktext10, .blacktext12, a.searchlinkSmall, a.searchlinkSmall:link, a.searchlinkSmall:visited{ color:FFFFFF; font-weight:normal; font-style:normal; font-family:Arial, verdana, arial, sans-serif; } .orangetext15, .lightbluetext8, .whitetext12, .nametext, .btext, .redtext, .redbtext{ color:FFFFFF; font-weight:bold; font-style:normal; font-family:Arial, verdana, arial, sans-serif; } a, a:link, a:visited, a.navbar, a.navbar:link, a.navbar:visited, a.man, a.man:link, a.man:visited, a.redlink, a.redlink:visited{ color:FFFFFF; font-weight:normal; font-style:normal; font-family:Arial, verdana, arial, sans-serif; } a:hover, a:active, a.navbar:hover, a.navbar:active, a.man:hover, a.man:active, a.searchlinkSmall:hover, a.searchlinkSmall:active, a.redlink:hover, a.redlink:hover{ color:CCCCCC; font-weight:normal; text-decoration:line-through ; font-style:normal; font-family:Arial, verdana, arial, sans-serif; } a img{ filter:gray, alpha(opacity=70) ; opacity:0.7; -moz-opacity:0.7; } a:hover img{ filter:gray, alpha(opacity=70) alpha(opacity=100) ; opacity:1; -moz-opacity:1; }
a .text
{
font-weight: bold;
font-family: Arial, Helvetica, sans-serif;
}
body, html {visibility:visible !important; display:block !important}
..
No me preguntes nada porque no se nada, solo que si lo pegas ahi te saldra más parecido a lo que quieres.
