re formatting css - collapse redundant paths?
/* example one: different attributes */
div#main_work > div.main_work table.data td span.rating,
div#main_work > div.main_work table.data td span.follow
   { white-space: nowrap; vertical-align: center; }

/* example two: same upstream, different downstream */
div#main_work > div.main_work > form table,
div#main_work > div.main_work > table,
div#main_work > div.main_work div table
   { width: 100%; margin: 0px;  -moz-box-sizing: border-box; box-sizing: border-box; }

/* example one: different attributes */
.main_work .rating,
.main_work .follow
   { white-space: nowrap; vertical-align: center; }

/* example two: same upstream, different downstream */
.main_work table,
.main_work form table,
.main_work div table
   { width: 100%; margin: 0px;  -moz-box-sizing: border-box; box-sizing: border-box; }
