CSS syntax to not display .ms-long class as well as a title attritubute

All, What would the syntax be to not display an item whose class is of .ms-long and where the title is equal to in this example - embedwaiver - I tried the following without any luck:

<style type="text/css">

.ms-long, [title~="embedwaiver"]
{
 display:none;
}
  
</style>
