What you see here is HTML and CSS code for a table, that is supposed to be white and blue.
INSTRUCTIONS ask that the ODD columns are BLUE, but instead everything has a blue background. I cannot figure it out :(
help appreciated, thanks!!!

Answer 1

Here is CSS that will get the job done at the table cell level. If you don't want the table header to have the blue and white colors, just remove the th selectors from the CSS.
th:nth-child(even), td:nth-child(even) {
background: white;
}
th:nth-child(odd), td:nth-child(odd) {
background: blue;
}
<table>
<thead>
<tr>
<th>Package Name</th>
<th class="text">Description</th>
<th>Nights</th>
<th>Cost per Person</th>
</tr>
</thead>
<tbody>
<tr>
<td>This is stesg</td>
<td>This is stesg</td>
<td>This is stesg</td>
<td>This is stesg</td>
</tr>
<tr>
<td>This is stesg</td>
<td>This is stesg</td>
<td>This is stesg</td>
<td>This is stesg</td>
</tr>
</tbody>
</table>

Answer 2

in your css add
tr:nth-child(odd){
backgound-color:blue;
}

Answer 3

Please check the code below. If you want the table header in a different color then you are nesting thead tr selectors and setting the background color from the CSS.
table {
border: 2px solid #3399cc;
border-collapse: collapse;
}
thead tr {
background-color: #140c12;
color: #fff;
}
th {
padding: 0.5em;
border: 2px solid #3399cc;
}
td {
padding: 0.5em;
border: 2px solid #3399cc;
text-align: center;
}
tbody tr:nth-child(odd) {
background-color: #eb7d4b;
}
.text {
text-align: left;
}
<div id="special">
<table>
<thead>
<tr>
<th>Package Name</th>
<th class="text">Description</th>
<th>Nights</th>
<th>Cost per Person</th>
</tr>
</thead>
<tbody>
<tr>
<td>Weekend Escape</td>
<td class="text">
Two breakfasts, a trail map, and a picnic snack
</td>
<td>2</td>
<td>$450</td>
</tr>
<tr>
<td>Zen Retreat</td>
<td class="text">
Four breakfasts, a trail map, a picnic snack, and a pass for the
daily sunrise Yoga session
</td>
<td>4</td>
<td>$600</td>
</tr>
<tr>

<td class="text">
Two breakfasts, two hours of kayak rental daily, and a trail map
