Text Colors

Use w3-text-* classes to style text with Flat UI colors.

Example:

<p class="w3-text-green">This is green text.</p>
<p class="w3-text-orange">This is orange text.</p>
<p class="w3-text-purple">This is purple text.</p>

Hover Effects

W3.CSS offers hover classes like w3-hover-* to apply Flat UI colors when hovering over elements.

Example:

<button class="w3-button w3-blue w3-hover-red">Hover Me</button>
<button class="w3-button w3-green w3-hover-yellow">Hover Me</button>

Combining Flat UI Colors

Flat UI colors can be paired to create stunning effects. For example, you can use contrasting colors for text and background.

Example:

<div class="w3-blue w3-padding">
  <h3 class="w3-text-white">Flat UI Blue Background with White Text</h3>
</div>

Practical Applications of Flat UI Colors

  • Call-to-Action Buttons: Use bold Flat UI colors to make CTAs stand out. 
<button class="w3-button w3-red">Sign Up</button>
<button class="w3-button w3-green">Learn More</button>
  • Headers and Sections: Differentiate sections of your webpage with unique Flat UI colors. 
<div class="w3-purple w3-padding">Header Section</div>
<div class="w3-light-grey w3-padding">Content Section</div>
  • Interactive Elements: Enhance user engagement with hover effects and active states.

Accessibility and Best Practices

  1. Contrast: Ensure text has sufficient contrast against background colors for readability.
    • Use tools to test contrast ratios for compliance with accessibility standards.
  2. Consistency: Stick to a limited palette to maintain a cohesive design.
  3. Responsive Testing: Flat UI colors should look great on both light and dark mode settings.

Customizing Flat UI Colors

If you want to expand beyond W3.CSS’s default palette, you can define your own colors while leveraging W3.CSS utilities.

Example:

<style>
  .custom-flat-color {
    background-color: #2ecc71; /* Flat UI Green */
    color: white;
  }
</style>

<div class="custom-flat-color w3-padding">Custom Flat UI Color</div>
