Custom CSS for nav bar stopped working

Hey everyone, 

I was updating some simple text on my website today and after a while, I noticed the custom CSS in my navigation bar just stopped working.  I had it set up to have the last 2 links of my nav bar to be coloured buttons. I didn't touch anything besides a text block, so I am very confused. If there is any code wizard here, help would be much appreciated, pretty please and thank you 🙃

Here is the code I have:

div#mainNavWrapper nav>div:nth-last-child(2) a{
    color: #fff !important;
    padding:10px 20px !important;
    border: 0px solid #000 !important;
    background-color: #8d073a !important;
    border-radius:10px !important;
    }

div#mainNavWrapper nav>div:nth-last-child(2) a:hover{
    color: #fff !important;
    background-color:#000 !important;
    }

div#mainNavWrapper nav>div:last-child a{
    color: #fff !important;
    padding:10px 20px !important;
    border: 0px solid #000 !important;
    background-color: #564f52!important;
    border-radius:10px !important;
    }

div#mainNavWrapper nav>div:last-child a:hover{
    color: #fff !important;
    background-color:#000 !important;
    }
 

I see your CSS box, currently has a syntax error. Can you send all current code in CSS box? We can check easier. Click this icon to add code

Sure thing, let me know if this works:

div#mainNavWrapper nav>div:nth-last-child(2) a{
    color: #fff !important;
    padding:10px 20px !important;
    border: 0px solid #000 !important;
    background-color: #8d073a !important;
    border-radius:10px !important;
    }

div#mainNavWrapper nav>div:nth-last-child(2) a:hover{
    color: #fff !important;
    background-color:#000 !important;
    }

div#mainNavWrapper nav>div:last-child a{
    color: #fff !important;
    padding:10px 20px !important;
    border: 0px solid #000 !important;
    background-color: #564f52!important;
    border-radius:10px !important;
    }

div#mainNavWrapper nav>div:last-child a:hover{
    color: #fff !important;
    background-color:#000 !important;
    }

Thank you, your correction did the trick!
