天命终不由人

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 can be done easily using pseudo selectors nth-child.

#table tr:nth-child(odd){background:red}
#table tr:nth-child(even){background:blue}

<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>

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>

tr:nth-child(even) {

}

 tr:nth-child(odd) {

}

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>

you can try selecting each row through CSS. In your case:

table tr:first-child{background:red}    or   table tr:nth-child(1){background:red}

table tr:nth-child(2){background:blue}

table tr:nth-child(3){background:orange}

table tr:nth-child(4){background:yellow}

table tr:last-child{background:purple} or table tr:nth-child(5)
{background:purple}

The below small piece of code should change the color table row.
```
 table, td, th {
    border: 1px solid red;
}

th {
    background-color: red;
    color: black;
}
```
