Custom CSS problem

Hello,

I am not sure if something in the theme is interfering with it but I cannot get the color of a rounded border to change from grey, no matter what color I put it is remains grey, other elements such as size etc are ok.

.highlighttext1 {padding: 15px 10px 10px 10px; background-color: #d16630; line-height: 1.0; display:inline;

border: 3px solid #bbf30a;

-moz-border-radius-topleft: 5px;

-moz-border-radius-topright:5px;

-moz-border-radius-bottomleft:5px;

-moz-border-radius-bottomright:5px;

-webkit-border-top-left-radius:5px;

-webkit-border-top-right-radius:5px;

-webkit-border-bottom-left-radius:5px;

-webkit-border-bottom-right-radius:5px;

border-top-left-radius:5px;

border-top-right-radius:5px;

border-bottom-left-radius:5px;

border-bottom-right-radius:5px;

}

I have tried with and without !important!

Any ideas?

Thanks

Andrew
