HTML Td Class Attribute - Dofactory

HTML <td> class Attribute HTML <tbody> HTML <template>

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

Classnames are defined in a stylesheet or in a local <style> element.

Classes, i.e. classnames, are used to style elements.

Using class

#

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

Multiple classnames are separated by a space.

JavaScript uses classes to access elements by classname.

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

Syntax

#

<td class="classnames">

Values

classnames	One or more space-separated class names.

More Examples

#

A class attribute styling <td> elements. Clicking the button toggles a classname that changes the background color of the table cells.

First name	Last name
Denice	Hobermann
Paulo	Cornell

Toggle class <style> table.tb { width:300px; border-collapse: collapse; } .tb th, .tb td { border: solid 1px #777; padding: 5px; } .tb th { background: #3630a3; color: white; text-align:left; } .tcell { background: #f6f8ff; } .tlite { background: #fff; } </style> <table class="tb"> <tr> <th>First name</th> <th>Last name</th> </tr> <tr> <td class="tcell">Denice</td> <td class="tcell">Hobermann</td> </tr> <tr> <td class="tcell">Paulo</td> <td class="tcell">Cornell</td> </tr> </table> <br /> <button onclick="toggle();">Toggle class</button> <script> let toggle = () => { let elements = document.getElementsByClassName("tcell"); [].forEach.call(elements, element => element.classList.toggle("tlite")); } </script> Try it live

Code explanation

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

The class attribute in <td> assigns one classname.

Repeatedly clicking the button calls JavaScript which locates all the <td> tags using classnames.

It then toggles the another class, changing the background and text color.
