Can’t remove text-decoration

Hi

I’m trying to remove the hyperlink underlining from the plugin. I’ve added the following in as custom css, but it’s not working. Please could you advise.

#sb_instagram .sb_instagram_header a { 
        outline: none;
	text-decoration: none !important;
}

#sb_instagram .sb_instagram_header a:link { 
	text-decoration: none !important;
}

#sb_instagram .sb_instagram_header a:hover { 
	text-decoration: none !important;
}

#sb_instagram a,
#sb_instagram a:hover,
#sb_instagram a:focus,
#sb_instagram a:active {
  outline: none;
  text-decoration: none !important;
}

#sb_instagram a {
  text-decoration: none !important;
}

Many thanks.
