Its value is CSS that defines the appearance of the tr element.

Using style

#

The style attribute specifies the style, i.e. look and feel, of the <tr> element.

A style contains any number of CSS property/value pairs, separated by semicolons (;).

The style attribute overrides any other style that was defined in a <style> tag or an external CSS file.

This inline styling affects the current <tr> element only.

Syntax

#

<tr style="CSS-styles">

Values

#

Value	Description
CSS-styles	One or more CSS property/value pairs separated by semicolons (;).

 .tbl th, .tbl td { padding:3px; border: 1px solid #777; }
</style>

<table id="mytb" class="tbl">
  <tr style="background-color:navy;color:white;">
    <th>First Name</th>
    <th>Last Name</th>
  </tr>
  <tr style="background-color:aliceblue;">
    <td>Denice</td>
    <td>Hobermann</td>
  </tr>
  <tr style="background-color:aliceblue;">
    <td>Timothy</td>
    <td>O'Neill</td>
  </tr>
  <tr style="background-color:aliceblue;">
    <td>Jane</td>
    <td>Hollander</td>
  </tr>
</table>

<br />
<button type="button" onclick="toggle();">Toggle style</button>

<script>
  let toggle = () => {
    let elements = document.getElementById("mytb").getElementsByTagName("tr");
    [].forEach.call(elements, element => {
        if (element.style.backgroundColor === "aliceblue") {
          element.style.backgroundColor = "white";
        } else if (element.style.backgroundColor === "white"){
          element.style.backgroundColor = "aliceblue";
        }
    });
  }
</script>

Code explanation

The style attribute assigns a background to the <tr> elements.

Clicking the button calls JavaScript which locates all the <tr> elements.

It then iterates over the elements and changes the background color.
