title color and image description

hi all,

in the bwg_frontend.css file I can not change the font color for bwg_image_title and bwg_image_description.
To put it in the center of the photo and on the page I have created the text-align: center command on appearance / personalize / add css.

.bwg_image_info,
.bwg_image_rate,
.bwg_image_hit {
   display: inline-block;
   position: relative;
   text-decoration: none;
   word-wrap: break-word;
   z-index: 11;
   text-align: center;

but if I add these two strings the color and the font do not change:

`.bwg_image_info,
.bwg_image_rate,
.bwg_image_hit {
   display: inline-block;
   position: relative;
   text-decoration: none;
   word-wrap: break-word;
   z-index: 11;
   text-align: center;
font-family: Arial;
color: # 000000;’

How can I solve the problem??
thank you
