My apologies; I asssumed you were the owners. My bad, and thank you for assistance.

I am using Joomla.

In case its joomla you need to go to template manager and see if you you can add custom css to your template in its settings. But the CSS code might be different, need to see the site for this.

I tried pasting that before into custom CSS and it didn't work; it is www.finishingandcoating.com

Thank you

Try this:

div#js-jobs-wrapper div.js-toprow div.js-data div.js-first-row span.js-jobtype {
 display: none;
}

I added it, refreshed it all, but it doesn't seem to have removed it.

I've attached some screenshots

Hm, it more tricky then. You need to find out how to add this code to your CSS. Check cache too!
This is what I see in develeper tools, though:   

Edit: its done, hey, I can see it on your site! If you cant see it on your site press CTRL F5, (clearing cache)
