How to add css to specific blocks or view with CSS injector module?
I am try already this but i think it would be helpfull

Use php section to add css against any view or block
and try this one 

&lt;?php
if ( $block-&gt;module == 'your_block_id/name'){
          //add some code here
}
?&gt;


Or can do it by add a class in view or block
