How to style the Scrolling Block of text in 7.1 as bold and italic?

Is there Custom CSS to style the Scrolling Block of text in 7.1 as bold, italic paragraph text at 50% black. I'm working in a trial site in 7.1, and I can not unlock the site due to client confidentiality.

Thanks for having a look.

You are amazing! Thank you. That worked.

What would the code be for 50% black?

Thanks again,

Brad

Here's the complete code. I added the color attribute, and it worked for 50% Black.

.marquee-block, .marquee-block p, .marquee-block h1 {
    font-weight: normal;
    font-style: italic;
  	color: #808080;
}

Thank you again for your help.

Sorry about that. Your code is correct. I also updated the original answer I gave.

I like your solve for the color best. Thank you kind sir.
