Suppose I have two HTML tables named table1 and table2. If I want to have different background of every alternative three rows of table2, how can I achieve that using CSS? For example set background of first 3 rows as blue, then another 3 rows as green, again another 3 rows as blue, again another 3 rows as green and so on. Basically I want two different background colors for every three rows in alternate. I found CSS styling for even and odd rows, or every nth rows, but not for this case. I have attached the screenshot of sample table. Rather than hard coding in individual row like in this code, I want to do it in CSS styling.
table {
font-family: arial, sans-serif;
border-collapse: collapse;
width: 100%;
}
td,
th {
border: 1px solid #dddddd;
text-align: left;
padding: 1px;
}<table id="table2">
<tr>
<th>Company</th>
<th>Contact</th>
<th>Country</th>
</tr>
<tr bgcolor="#dddddd">
<td>Alfreds Futterkiste</td>
<td>Maria Anders</td>

<tr bgcolor="#dddddd">

Reset to default 5You can use "nth-child" to achieve this.
tr:nth-child(6n+1),
tr:nth-child(6n+2),
tr:nth-child(6n+3) {
background: #dddddd;
}
Try with below snippet
table {
font-family: arial, sans-serif;
border-collapse: collapse;
width: 100%;
}
td, th {
border: 1px solid #dddddd;
text-align: left;
padding: 1px;
}
tr:nth-child(6n+1),
tr:nth-child(6n+2),
tr:nth-child(6n+3) {
background: #dddddd;
}
<table id="table2">
<tr>
<th>Company</th>
<th>Contact</th>
<th>Country</th>
</tr>
<tr>
<td >Alfreds Futterkiste</td>
<td>Maria Anders</td>
<td>Germany</td>
</tr>
<tr>
<td >Centro ercial Moctezuma</td>

</table>You want the alternative color for every three group of rows. Let explain the formula of css tr:nth-child(6n+1),
tr:nth-child(6n+2),
tr:nth-child(6n+3) where n=0,1,2,3......this tr selection will start from 1-3, 7-9....
Likewise tr:nth-child(6n+4),
tr:nth-child(6n+5),
tr:nth-child(6n+6) where n=0,1,2,3......this tr selection will start from 4-6, 10-12....
tr:nth-child(6n+1),
tr:nth-child(6n+2),
tr:nth-child(6n+3) {
background: blue;
}
tr:nth-child(6n+4),
tr:nth-child(6n+5),
tr:nth-child(6n+6) {
background: green;
}
table {
color: #fff;
}<table id="table2">
<tr>

</table>You can use javascript for set the background-color
$('document').ready(function(){
$('#table1 tr').each((index, value) => {
if(index % 3 != 0){
value.css({'background-color': '#0000FF'});
}else{
value.css({'background-color': '#00FF00'});
}
});
});
or define two css class
.blue {background-color: #0000FF;}
.green {background-color: #00FF00;}
and assign this class in all tr of table you want
You can separate the header and body and use nth-child concept
<!DOCTYPE html>
<html>
<head>
<style>
table {
font-family: arial, sans-serif;
border-collapse: collapse;
width: 100%;
}
table tbody tr:nth-child(6n+1),table tbody tr:nth-child(6n+2),table tbody
tr:nth-child(6n+3) {
background: #dddddd;
}
td, th {
border: 1px solid #dddddd;
text-align: left;
padding: 1px;
}
</style>
</head>
<body>
<table id="table2">
