How to change the posts text color in vBulletin?
The posts text color and the quote text color can be changed by entering the preferred color in the .postcontent definition.
Check the following example:
.postcontent {
text-align: right;
word-wrap: break-word;
color: green;
}
The variable definition can be altered through your vBulletin admin panel > Styles & Templates > Style Manager > Edit Templates > Go > CSS Templates > postbit.css.
