HTML <tbody> class Attribute

The class attribute on a <tbody> tag assigns one or more classnames to the table body element. Classes are used to style elements. Classnames are defined in a stylesheet or in a local <style> element.

Example

  .tb th { background: #3630a3; color: white; text-align:left; }
  .tbody { background: #f6f8ff; }
</style>

<table class="tb">

  <tbody class="tbody">

Using class

The class attribute assigns one or more classnames to the <tbody> tag.

Multiple classnames are separated by a space.

Classes (i.e. classnames) are used for styling the tbody element.

JavaScript uses classes to access one or more elements by classname.

Tip:  class is a global attribute that can be applied to any HTML element.

More Examples

A class attribute styling a <tbody> element.

Paulo Cornell

<style>
  table.tbl { width:300px; border-collapse: collapse; }
  .tbl th, .tbl td { border: solid 1px #777; padding: 5px;  }
  .tbl th { background: #3630a3; color: white; text-align:left; }
  .tbody { background: #f6f8ff; }
  .tbody-light { background: white; }
</style>

<table class="tbl">
  <thead>
    <tr>
      <th>First name</th>
      <th>Last name</th>
    </tr>
  </thead>

  <tbody id="mytbody" class="tbody">
    <tr>
      <td>Denice</td>
      <td>Hobermann</td>
    </tr>
    <tr>
      <td>Paulo</td>
      <td>Cornell</td>
    </tr>
  </tbody>
</table>

<br />
<button onclick="toggle();">Toggle class</button>

<script>
  let toggle = () => {
     let element = document.getElementById("mytbody");
     element.classList.toggle("tbody-light");
  }
</script>

Code explanation

Two CSS classes are defined in the <style> element.

The class attribute in <tbody> assigns one classname.

Repeatedly clicking the button toggles another class, changing the background and text color of the <tbody> element.
