What is Display in W3.CSS?

The display property defines how an element is rendered on a webpage. With W3.CSS, you can easily toggle between display modes, hide elements, or control their visibility across different screen sizes—all without writing custom CSS.

How to Use W3.CSS Display Classes

1. Hiding and Showing Elements

Example: Hiding Elements

<div class="w3-hide">
  This text is hidden by default.
</div>

Example: Showing Hidden Elements

<div class="w3-hide" id="myElement">
  This text is initially hidden.
</div>
<button class="w3-button w3-blue" onclick="document.getElementById('myElement').classList.remove('w3-hide')">
  Show Text
</button>

2. Responsive Visibility

Hide or show elements based on screen size.

<div class="w3-hide-small w3-light-grey" style="padding: 10px;">
  This text is hidden on small screens.
</div>
<div class="w3-show-small w3-light-blue" style="padding: 10px;">
  This text is only visible on small screens.
</div>

3. Block and Inline Display

Example: Block Display

<span class="w3-block w3-light-grey" style="margin-bottom: 10px;">
  This span behaves like a block element.
</span>

Example: Inline Display

<div class="w3-inline w3-light-blue" style="margin-right: 10px;">Inline Item 1</div>
<div class="w3-inline w3-light-green">Inline Item 2</div>

4. Inline-Block Display

<div class="w3-inline-block w3-border w3-padding" style="margin-right: 10px;">
  Inline-Block Item 1
</div>
<div class="w3-inline-block w3-border w3-padding">
  Inline-Block Item 2
</div>

5. Display Containers for Layouts

W3.CSS provides display containers to control element positioning.

Example: Display Container

<div class="w3-display-container w3-light-grey" style="height: 200px; width: 100%;">
  <div class="w3-display-top w3-padding">Top Content</div>
  <div class="w3-display-middle w3-padding">Middle Content</div>
  <div class="w3-display-bottom w3-padding">Bottom Content</div>
</div>

Best Practices

  1. Use Responsive Classes for Adaptive Design
    Always test visibility across different devices for a seamless user experience.
  2. Keep the Layout Simple
    Use w3-display-container sparingly to avoid over-complicating layouts.
  3. Combine with Other Classes
    Mix display classes with W3.CSS padding, margins, and colors for enhanced visuals.
  4. Fallback for JavaScript
    Ensure that dynamically hidden content (e.g., w3-hide) is still accessible to search engines and users without JavaScript enabled.

Practical Use Cases

1. Responsive Navigation Menus

<nav class="w3-bar">
  <a href="#" class="w3-bar-item w3-button w3-hide-small">Home</a>
  <a href="#" class="w3-bar-item w3-button w3-hide-small">About</a>
  <a href="#" class="w3-bar-item w3-button w3-hide-small">Contact</a>
  <a href="#" class="w3-bar-item w3-button w3-show-small w3-light-blue">Menu</a>
</nav>

2. Image Gallery with Inline-Block

<div class="w3-inline-block w3-border w3-padding w3-margin">
  <img src="https://via.placeholder.com/150" alt="Image 1">
</div>
<div class="w3-inline-block w3-border w3-padding w3-margin">
  <img src="https://via.placeholder.com/150" alt="Image 2">
</div>

3. Centered Modals or Dialog Boxes

<div class="w3-display-container" style="height: 100vh; background-color: rgba(0,0,0,0.5);">
  <div class="w3-display-middle w3-padding w3-card w3-white">
    <h3>Centered Modal</h3>
    <p>This modal is perfectly centered!</p>
  </div>
</div>
