Question

where do i get started here?

Use embedded CSS style sheets for the table and configure color red, margin 1px, text align center, use a structural pseudo-class that will apply the style to the 1^st row to have a dark blue background and to have a gray background of the odd-numbered table rows

Answer 1

<style>
table {
margin: 1px;
background-color: red;
text-align: center;
  
}

tr:nth-child(odd){background-color: grey}

th {
background-color: darkblue;

  
}
</style>

The above given code is css code for styling your table according to what you have asked. first row of table will be table head so "th { background-color: darkblue;}" this code will give it background color dark blue.For giving grey color for odd numbered table use the code "tr:nth-child(odd){background-color: grey}" tr is used for specifying table row.

The code section,

table {
margin: 1px;
background-color: red;
text-align: center; } will configure color red, margin 1px, text align center.
