Customizing Bootstrap CSS styles using CSS: A step-by-step guide

I am encountering an issue with the navbar in my Bootstrap project. Despite having specified the background color to be aqua in my boot.css file, it is not overriding the default dark color set in the Bootstrap CSS.

To customize the styling of the navbar and override Bootstrap's CSS, you can add more specific CSS rules in your boot.css file. Using more specific selectors or using the !important declaration can help you override the default styling. For example, you can target the navbar class directly in your custom CSS to ensure that your styles take precedence.

Answer №1

To change the appearance of the navigation bar, you should remove the bg-dark class from the <navbar> element and replace it with one of the Bootstrap background color classes like .bg-primary or any other color of your choice. For example:

<nav class="navbar navbar-expand-md bg-primary navbar-dark">

You can also create your own background color class, such as:

.bg-aqua {
    background-color: aqua !important;
}

Then, add this custom class to the <navbar> element:

<nav class="navbar navbar-expand-md bg-aqua navbar-light">

Keep in mind that using navbar-dark and navbar-light classes will determine whether the text in your navigation bar appears white or black.

Refer to the Bootstrap Navbar Color Scheme documentation for more information.

Answer №2

If you're looking to change the color, using an id could be a good option. However, if you need to change multiple elements at once, this may not be the most efficient solution for you.

To change the color, simply add the id of your choice in the following line (for example, id="navigationID"):

<nav class="navbar navbar-expand-md bg-dark navbar-dark" id="navigationID">

Then, specify the background color you want in the CSS for this id:

#navigationID{
  background-color: aqua !important;
}

Here is an example of how this works:

Answer №3

When using bootstrap bg-dark, it has its own unique style with !important. Therefore, in order to override the bootstrap style, you need to provide more specificity than the bootstrap style or completely remove the bootstrap style. Check out the details below:
