RevSlider_Individual slide edit

[j powers+ 8]

Need a little help, I cant seem to id the need CSS to edit. I am trying to add this 

.revslider-container h2.slider-text{

background: rgb(54, 25, 25);

background: rgba(54, 25, 25, .5);

}

But just to t he text on one slide, it is adding to both slides at the moment.  How can I identify the text on just one slide using Chrome inspect element?

 

Thanks
