Key Features of W3.CSS Layout

1. The Grid System

The W3.CSS grid system divides your page into 12 equal columns, giving you maximum flexibility.

Basic Grid Example

<div class="w3-row">
  <div class="w3-col s6 w3-light-grey">50% Width</div>
  <div class="w3-col s6 w3-grey">50% Width</div>
</div>

Custom Column Sizes

<div class="w3-row">
  <div class="w3-col s4 w3-light-grey">33% Width</div>
  <div class="w3-col s8 w3-grey">66% Width</div>
</div>

2. Containers

Use containers to define the boundaries of your layout.

<div class="w3-container w3-light-grey">
  <h3>Content Inside a Container</h3>
  <p>Containers add padding and structure to your layout.</p>
</div>

3. Responsive Rows and Columns

Create layouts that adjust to different screen sizes using s, m, and l classes for small, medium, and large screens.

<div class="w3-row">
  <div class="w3-col s12 m6 l4 w3-light-grey">Small 12, Medium 6, Large 4</div>
  <div class="w3-col s12 m6 l4 w3-grey">Small 12, Medium 6, Large 4</div>
  <div class="w3-col s12 m6 l4 w3-dark-grey">Small 12, Medium 6, Large 4</div>
</div>

4. Fixed and Fluid Layouts

  • Fixed Layout: Use w3-container for a fixed-width layout with padding.
  • Fluid Layout: Use w3-row for a full-width layout.

Example

<div class="w3-container w3-light-grey">
  <p>Fixed layout with padding.</p>
</div>

<div class="w3-row w3-grey">
  <p>Fluid layout spanning full width.</p>
</div>

5. Header, Footer, and Sidebar Layouts

Create common web layouts like headers, footers, and sidebars.

Full Page Layout

<div class="w3-container w3-blue">
  <h1>Header</h1>
</div>

<div class="w3-row">
  <div class="w3-col s3 w3-light-grey">
    <h3>Sidebar</h3>
  </div>
  <div class="w3-col s9 w3-white">
    <h3>Main Content</h3>
  </div>
</div>

<div class="w3-container w3-blue">
  <h3>Footer</h3>
</div>

6. Alignment and Spacing

Use alignment and spacing classes to fine-tune your layout.

Center Content

<div class="w3-container w3-center">
  <h3>Centered Content</h3>
</div>

Spacing Between Elements

<div class="w3-container w3-padding-16">
  <h3>Content with Padding</h3>
</div>

7. Card-Based Layout

Cards are great for creating structured layouts with defined sections.

<div class="w3-card w3-padding">
  <h3>Card Title</h3>
  <p>This is a card layout with padding and a shadow effect.</p>
</div>

8. Flexbox Utility

Leverage w3-flex for advanced alignment and distribution.

Example

<div class="w3-container w3-flex w3-light-grey">
  <div class="w3-padding">Item 1</div>
  <div class="w3-padding">Item 2</div>
  <div class="w3-padding">Item 3</div>
</div>

Practical Applications

1. Blog Layout

<div class="w3-row">
  <div class="w3-col s12 m8 w3-light-grey">
    <h2>Blog Post</h2>
    <p>Main content goes here.</p>
  </div>
  <div class="w3-col s12 m4 w3-grey">
    <h3>Sidebar</h3>
    <p>Related content or links.</p>
  </div>
