Here's a corrected version of the CSS that should work with MediaWiki 1.42.1. A few adjustments have been made to ensure the styles are properly applied: css Copy code /* Apply alternating colors, padding, rounded corners, and Georgia font to all tables */ table.wikitable { border-collapse: separate; /* Allows border-radius to work */ border: 4px solid #2b2b2b; /* Darker gray border */ border-radius: 8px; /* Rounded corners */ overflow: hidden; /* Ensures content respects rounded corners */ font-family: "Georgia", serif; /* Georgia font for the entire table */ color: #c1c1c1; /* Default text color for table */ background-color: #4c4c4c; /* Default background color for table */ border-color: #666666; /* Darker gray border */ } /* Add extra padding to all table cells (header and data) */ table.wikitable th, table.wikitable td { padding: 12px 16px; /* 12px headroom (top/bottom), 16px side room (left/right) */ border: 1px solid #666666; /* Slightly darker gray border for cells */ color: #c1c1c1; /* Text color for table data cells */ } /* Apply alternating row colors */ table.wikitable tr:nth-child(even) { background-color: #333333; /* Darker gray for even rows */ } table.wikitable tr:nth-child(odd) { background-color: #4d4d4d; /* Dark gray for odd rows */ } /* Style the table headers */ table.wikitable th { background-color: #595959; /* Header background color */ color: #ffffff; /* White text for header contrast */ font-weight: bold; /* Bold the header text */ font-size: 1.2em; /* Slightly larger font size for headers */ font-family: "Georgia", serif; /* Apply Georgia font to headers */ border: 1px solid #666666; /* Darker gray border for header cells */ } /* Keep the styling for mw_metadata tables */ table.mw_metadata td, table.mw_metadata th { color: #c1c1c1; background-color: #4c4c4c; border-color: #666666; } table.mw_metadata th { background-color: #595959; }
