Ajustar slider en blog

[triumphalis]

Buenas. Necesito un poco de ayuda. Puse el siguiente código en mi blog, (slider automatico ultimas entradas) pero me descuadra por completo el blog (columna derecha). ¿A que se debe?
Mi blog www.tweetnastic.com

Código:

<style scoped="" type="text/css">
#coinautoslide{margin:0 auto;border:4px solid white;border-radius:2px;font:normal normal 11px Verdana,Geneva,sans-serif;line-height:1.6em}
.coin-slider{overflow:hidden;zoom:1;position:relative}
.coin-slider a{text-decoration:none;outline:none;border:none}
.cs-buttons{font-size:0;padding:10px;float:left}
.cs-buttons a{margin-left:5px;height:10px;width:10px;float:left;border:1px solid #B8C4CF;color:#B8C4CF;text-indent:-1000px}
.cs-active{background-color:#B8C4CF;color:#FFFFFF}
.cs-buttons a{border-radius:50%;background:#CCC;background:-webkit-linear-gradient(top,#CCCCCC,#F3F3F3);background:-moz-linear-gradient(top,#CCCCCC,#F3F3F3);background:-o-linear-gradient(top,#CCCCCC,#F3F3F3);background:-ms-linear-gradient(top,#CCCCCC,#F3F3F3);background:linear-gradient(top,#CCCCCC,#F3F3F3)}
a.cs-active{background:#599BDC;background:-webkit-linear-gradient(top,#599BDC,#3072B3);background:-moz-linear-gradient(top,#599BDC,#3072B3);background:-o-linear-gradient(top,#599BDC,#3072B3);background:-ms-linear-gradient(top,#599BDC,#3072B3);background:linear-gradient(top,#599BDC,#3072B3);border-radius:50%;box-shadow:0 0 3px #518CC6;border:1px solid #3072B3!important}
.cs-title{width:100%;padding:5px 0;background-color:#000000;color:#FFFFFF}
.cs-title strong{display:block;font-size:120%}
.cs-title p{margin:0}
.cs-title cite{font-size:90%}
.cs-title strong,.cs-title cite,.cs-title p{padding:0 10px}
.cs-prev,.cs-next{background-color:#000000;color:#FFFFFF;padding:0 10px}
</style>
