W3.CSS Cells

Welcome to The Coding College, where we break down complex web design concepts into simple, actionable tutorials. In this guide, you’ll learn how to use W3.CSS Cells to organize your content effectively and responsively.

What Are “Cells” in W3.CSS?

While W3.CSS doesn’t have a specific class named .w3-cell, the concept of “cells” typically refers to content blocks inside a layout structure, especially when using rows and columns — similar to a table-like grid.

In W3.CSS, cells are created using a combination of w3-row, w3-col, and other responsive layout utilities.

Example: Basic Row with Cells

<div class="w3-row">
  <div class="w3-col s4 w3-padding w3-red">Cell 1</div>
  <div class="w3-col s4 w3-padding w3-blue">Cell 2</div>
  <div class="w3-col s4 w3-padding w3-green">Cell 3</div>
</div>

Each w3-col in a w3-row is essentially a cell, taking up a portion of the 12-column layout system.

Layout Breakdown: Columns = Cells

W3.CSS divides a row into 12 parts. You can think of each part as a cell, and each column (e.g., s4, s6, etc.) spans across multiple cells:

Using W3.CSS Grid as a Cell Layout

<div class="w3-row w3-border">
  <div class="w3-col s3 w3-center w3-light-grey w3-padding">Image</div>
  <div class="w3-col s9 w3-padding">
    <h4>Title</h4>
    <p>Description inside this cell area.</p>
  </div>
</div>

This example mimics a cell-based layout for media objects, ideal for blog cards, user profiles, or list items.

Cell-Based Design for Tables

W3.CSS also lets you create table-like cells using the w3-table class:

<table class="w3-table w3-bordered">
  <tr>
    <th>Cell Header 1</th>
    <th>Cell Header 2</th>
  </tr>
  <tr>
    <td>Cell Content A</td>
    <td>Cell Content B</td>
  </tr>
</table>

Each <td> here can be considered a cell within a tabular structure.

Advanced Use: Flexbox “Cells”

You can also make cells using Flexbox for modern layouts:

<div class="w3-container" style="display: flex;">
  <div class="w3-padding w3-orange" style="flex: 1;">Flex Cell 1</div>
  <div class="w3-padding w3-purple" style="flex: 2;">Flex Cell 2</div>
</div>

• flex: 1 and flex: 2 define relative cell widths
• These “cells” are dynamic and responsive

When to Use W3.CSS Cells

Tips for Clean Cell Design

• Use w3-row-padding to add spacing between cells
• Combine with w3-card, w3-border, and w3-shadow for styled boxes
• Add w3-responsive to make table cells mobile-friendly

Real-World Example: Feature Grid

<div class="w3-row-padding w3-light-grey">
  <div class="w3-third w3-center w3-padding">
    <i class="w3-xxlarge w3-text-blue w3-margin-bottom">💡</i>
    <h4>Easy to Use</h4>
    <p>W3.CSS cells are intuitive and quick to build with.</p>
  </div>
  <div class="w3-third w3-center w3-padding">
    <i class="w3-xxlarge w3-text-green w3-margin-bottom">⚡</i>
    <h4>Responsive</h4>
    <p>All layouts adapt beautifully to all devices.</p>
  </div>
  <div class="w3-third w3-center w3-padding">
    <i class="w3-xxlarge w3-text-red w3-margin-bottom">🎯</i>
    <h4>Lightweight</h4>
    <p>No bloated CSS — only what you need.</p>
  </div>
</div>

This is a perfect “cell block” layout for showcasing features.
