You asked the same question at Centering <UL> + Keeping <LI>'s Aligned and i already answered you.
Give your div a class name center. Assuming your div width is 200px, margin:0 auto will center and text-align:left will align the text to the left while maintaining its centering due to margin auto.
.center{
width:200px;
margin:0 auto;
text-align:left;
}
