Can I use <thead> inside <tbody> and <tfoot> apart from main <thead> of <table>?

I would like to style thead inside main components differently, but I don't understand, why higher specifity some of them does not react and some styles works on every <tr> while I specified it only to <tbody>.

I would like to try do it without classes.

Here is simple example:

<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
<style>
body {
    background-color: black;
    text-align: center;
    color: black;
}

table > thead   {background-color: pink;} /*0002 - to main thead*/   
table > tbody > thead > tr > th {background-color: skyblue; } /*0005 - to "Final students marks" and "Avarage marks in groups"*/


tbody > tr:nth-child(even) {background: #CCC;} /*0011*/
tbody > tr:nth-child(odd) {background: #FFF;} /* why it styling tfoot?? */

tfoot tr:nth-child(even) {background: sandybrown !important; /*why not work???*/ }
tfoot tr:nth-child(odd) {background: sandybrown !important;}
</style>
</head>
<body>
<table>
					<thead> 
						<tr><th>Number</th><th>Name</th><th>Surname</th><th>Group</th><th>Mark</th></tr>
					</thead>
                    
					<tbody>
						<thead><tr><th colspan="5">Final students marks</th></tr></thead>
                        
						<tr><td>1</td><td>Adam</td><td>Abacki</td><td>A</td><td>4</td></tr>
						<tr><td>2</td><td>Ewa</td><td>Babacka</td><td>B</td><td>5</td></tr>
						<tr><td>3</td><td>Edward</td><td>Cabacki</td><td>A</td><td>3</td></tr>
						<tr><td>4</td><td>Tomasz</td><td>Dadacki</td><td>A</td><td>4</td></tr>
						<tr><td>5</td><td>Anna</td><td>Kowalska</td><td>B</td><td>3</td></tr>
						<tr><td>6</td><td>Marek</td><td>Zawadzki</td><td>A</td><td>5</td></tr>
					</tbody>
                    
					<tfoot>
						<thead><tr><th colspan="5">Average marks in groups</th></tr></thead>
                        
						<tr><td>1</td><td colspan="2"></td><td>A</td><td>4</td></tr>
						<tr><td>2</td><td colspan="2"></td><td>B</td><td>4</td></tr>
					</tfoot>

<thead>

Permitted content: Zero or more <tr> elements.

Permitted parents: A <table> element.

So your table structure should be:

table
  thead
    tr
      th
  tbody
    tr
      td
  tfoot
    tr
      td

body {
  text-align: center;
}

table {
  width: 100%;
  border: 1px solid black;
  border-spacing: 0;
}

table>thead {
  background-color: pink;
  font-weight: bold;
}

table>tbody>tr:first-child>td,
table>tfoot>tr:first-child>td {
  font-weight: bold;
  background-color: skyblue;
}

tbody>tr:nth-child(odd) {
  background: #CCC;
}

tfoot>tr {
  background: sandybrown;
}

tbody>tr>td:first-child,
tfoot>tr>td:first-child {
  background: yellow;
}
<body>
  <table>
    <thead>
      <tr>
        <th>Number</th>
        <th>Name</th>
        <th>Surname</th>

      <tr>

      </tr>
    </tbody>
    <tfoot>
      <tr>
        <td colspan="5">Average marks in groups</td>
      </tr>
      <tr>

How to make table borders invisible with CSS, How do I make my table border invisible in HTML? It can appear either before or after the table’s tbody element, but will be rendered at the bottom of the table regardless of where it appears in the HTML (unless that default behavior is overridden with CSS). It’s a good idea to use tfoot, tbody, and thead to organize tables that contain complex data sets. These elements can be used by browsers and developers to allow users to scroll the contents of the table independently of the header and footer, providing a better user experience

thead Isn't valid inside of tbody (yes they're just tags but tables are from a different time with different browser rules). You CAN use multiple tbody tags to group things and css:first-child to color rows correctly.

body {
			background-color: black;
			text-align: center;
			color: black;
		}
thead {
	background-color: pink;
}

tbody > tr:nth-child(even) {
	background: #CCC;
}
tbody > tr:nth-child(odd) {
	background: #FFF;
}
/* remove important or other colors won't work */
/* just place AFTER other definition in CSS */
tbody:nth-child(3) tr {
	background: sandybrown;
}
/* place this after other definition to make everything blue */
tbody>tr:first-child {
	background: skyblue;
}
