I'm struggling with the code below:
<table>
<thead>
<th class='1'>Date</th>
<th class='2'>Start Time</th>
<th class='3'>End Time </th>
<th class='4'>Location</th>
</thead>
<tbody>
<td class='1'>Date</td>
<td class='2'>Start Time</td>
<td class='3'>End Time </td>
<td class='4'>Location</td>
</tbody>
</table>
and I have the following CSS
table {width:550px;}
.1 {width:60px; background-color:green;}
.2 {width:90px; background-color:blue;}
.3 {width:90px; background-color:red;}
.4 {width:100px; background-color:yellow;}
I'm facing an issue where the width isn't being set and the background color is not changing as expected. It seems like there might be a mistake in my code somewhere.
