How Can I Change the Bootstrap 4 Navbar Toggle Button Color?

Customizing Bootstrap 4 Navbar Toggle Button Color

Context:

In Bootstrap websites, smaller screens usually feature a hamburger menu button for navigation. This button, by default, has a particular color.

Question:

Can you modify the color of the Bootstrap 4 navbar toggle button?

Answer:

Using Bootstrap's Predefined Styles:

Bootstrap 4 utilizes SVG background images for the toggle icon. There are specific classes for different styles:

• .navbar-dark: Light-colored icon on dark backgrounds
• .navbar-light: Dark-colored icon on light backgrounds

Customizing the Icon:

If these predefined options don't suit your needs, you can create a custom SVG icon with the desired colors. For instance:

.custom-toggler .navbar-toggler-icon {
  background-image: url("data:image/svg+xml;charset=utf8,%3Csvg viewBox='0 0 32 32' xmlns='http://www.w3.org/2000/svg'%3E%3Cpath stroke='rgba(255,102,203, 0.5)' stroke-width='2' stroke-linecap='round' stroke-miterlimit='10' d='M4 8h24M4 16h24M4 24h24'/%3E%3C/svg%3E");
}

This code sets the icon color to pink. You can adjust the values in the rgba() function to match your preferred color.

Using External Icon Libraries:

Alternatively, you can use icons from libraries like Font Awesome, ensuring that you apply the necessary CSS classes to style them.

Updates in Bootstrap 4.0.0:

Previously known as navbar-inverse, the dark-themed navbar class is now navbar-dark, which produces lighter colors for links and the toggle button.
