Is there a shorthand way to write the following css classes that all have the same style?
.gtlab1-17, .gtlab1-19, .gtlab1-21, .gtlab2-17, .gtlab2-19, .gtlab2-21, .gtlab3-17, .gtlab3-19, .gtlab3-21 {margin-left:-3px;}
I need to avoid picking up:
.gtlab1-16, .gtlab2-16, .gtlab3-16
and
.gtlab1-15, .gtlab2-15, .gtlab3-15
which have different styles.
Thanks.
