Qual é minha questão:
Estou fazendo um tema no fórum de testes e como ainda sou iniciante na versão PUNBB, gostaria de saber em que parte do meu CSS personalizo as bordas vermelhas apresentadas no fórum deixando do as na cor roxa.

Meu CSS:

Código:

.vote {
float: right;
width: 32px;
margin-left: 32px;
}

/*CODES, QUOTES, SPOILERS

dl.codebox {
border-radius: 7px;
-moz-border-radius: 7px;
-webkit-border-radius: 7px;
margin-left: 9px;
margin-right: 7px;
margin-top: 2px;
margin-bottom: 4px;
}

blockquote{
font-size: 0.9em;
border-radius: 7px;
-moz-border-radius: 7px;
-webkit-border-radius: 7px;
margin-left: 2px;
margin-right: 7px;
margin-top: 5px;
margin-bottom: 3px;
}

blockquote cite{
border-bottom: 1px solid #dbdcd4;
padding-bottom: 0px;
}
