Mastering Dark Mode: How to Change Bootstrap Theme Colors in Dark Mode

Bootstrap's dark mode is a popular choice for creating visually appealing websites with a modern feel. But what if you want to customize the default dark mode color palette to match your brand or personal preferences? This article will guide you through the process of changing Bootstrap's theme colors specifically in dark mode.

Understanding the Challenge

Bootstrap's dark mode uses a predefined set of colors for its components. If you want to modify these colors, you need to override them using custom CSS. But the challenge lies in ensuring that these changes apply only to the dark mode, without affecting the default light mode.

The Code: A Basic Example

Let's say you want to change the background color of all navbar elements in dark mode to a deep purple. Here's a simple example using CSS:

@media (prefers-color-scheme: dark) {
  .navbar {
    background-color: #4527A0; /* Deep purple */
  }
}

This code snippet uses the @media (prefers-color-scheme: dark) rule to target only the dark mode. We then use the .navbar class selector to target the specific element we want to modify, and change the background-color property to our desired color.

Analyzing the Solution

This example demonstrates a key approach to customizing Bootstrap's dark mode colors:

  • Media Queries: Leverage @media queries to apply CSS rules specifically for dark mode. This ensures that the default light mode remains unaffected.
  • Class Selectors: Use specific class selectors to target the Bootstrap components you want to change. This allows for granular control over your color customization.

Beyond Basic Customization

You can apply this approach to customize any color used by Bootstrap components in dark mode. Here are a few more examples:

  • Changing the primary color:
@media (prefers-color-scheme: dark) {
  .btn-primary {
    background-color: #E91E63; /* Pink */
    border-color: #E91E63; /* Pink */
  }
}
  • Customizing text color:
@media (prefers-color-scheme: dark) {
  .text-body {
    color: #FFFFFF; /* White */
  }
}
  • Modifying the background of the entire body:
@media (prefers-color-scheme: dark) {
  body {
    background-color: #121212; /* Dark grey */
  }
}

Tips for Effective Dark Mode Color Customization

  • Choose colors wisely: Ensure good contrast between text and background colors for readability in dark mode.
  • Use a color palette: Consider using a pre-defined color palette for consistency and visual appeal.
  • Test your changes: Always test your customizations in both light and dark mode to ensure they function correctly.
