change color of rows in a table in HTML and CSS

Question

Trying to learn HTML and CSS and I have a simple question.

How can I give each row a different color in a table? For example row 1 is red, row 2 is blue etc.

This is my HTML code:

#table {
  font-family: Arial, Helvetica, sans-serif;
  width: 600px;
  border-collapse;
  collapse;
}
#table td,
#table th {
  font-size: 12x;
  border: 1px solid #4D365B;
  padding: 3px 7px 2px 7px;
}
#table th {
  font-size: 14px;
  text-align: left;
  padding-top: px;
  padding-bottom: 4px;
  background-color: #4D365B;
  color: #918CB5;
}
#table td {
  color: #000000;
  background-color: #979BCA;
}

<table id="table">
  <tr>
    <th>Company</th>
    <th>Contact
      <th>Country</th>
  </tr>
  <tr>
    <td>1</td>
    <td>2
      <td>3</td>
  </tr>
  <tr>
    <td>1</td>
    <td>2
      <td>3</td>
  </tr>
  <tr>
    <td>1</td>
    <td>2
      <td>3</td>
  </tr>
</table>

Answer 1

If I understand your question correctly and you want to give every row a different color? You have a few options...

• Add a class to each row and style those.
• Use the direct sibling selector tr + tr
• Use :nth-of-type

table tr {background: red;}
table tr:nth-of-type(2) {background: blue;}
table tr:nth-of-type(3) {background: green;}
table tr:nth-of-type(4) {background: yellow;}
table tr:nth-of-type(5) {background: grey;}

<table id="table">
  <tr>
    <th>Company</th>
    <th>Contact
      <th>Country</th>
  </tr>
  <tr>
    <td>1</td>
    <td>2
      <td>3</td>
  </tr>
  <tr>
    <td>1</td>
    <td>2
      <td>3</td>
  </tr>
  <tr>
    <td>1</td>
    <td>2
      <td>3</td>
  </tr>
  <tr>
    <td>1</td>
    <td>2
      <td>3</td>
  </tr>
</table>

You can also try like this

#table tr{background: red;}
#table tr:nth-child(2n+1){background: blue;}

#table {
font-family: Arial, Helvetica, sans-serif;
width:600px;
border-collapse;collapse;

#table td, #table th {
font-size:12x;
border:1px solid #4D365B;
padding: 3px 7px 2px 7px;

#table th {
font-size:14px;
text-align:left;
padding-top:px;
padding-bottom:4px;
background-color:#4D365B;
color:#918CB5;

#table td {
color:#000000;
background-color:#979BCA;
}

<table id="table">
<tr><th> Company</th><th>Contact<th>Country</th></tr>
<tr><td> 1</td><td>2<td> 3</td></tr>
<tr><td> 1</td><td>2<td> 3</td></tr>
<tr><td> 1</td><td>2<td> 3</td></tr>
