Bootstrap 4 Link in CSS File Example A Step-by-Step Guide

To link Bootstrap 4 in your CSS file, you can use the following steps:

1. Download Bootstrap 4 from the official website (https://getbootstrap.com/).
2. Extract the downloaded files and move the CSS file to your project’s CSS folder.
3. Open your HTML file and add the following code to the head section:

<link rel="stylesheet" href="path/to/bootstrap.min.css">

Replace “path/to/” with the actual path to the CSS file in your project.

4. In your CSS file, you can now reference the Bootstrap classes to style your HTML content.

For example, to style a button with Bootstrap classes, you can add the following code in your CSS file:

.btn-primary {
  background-color: #007bff;
  border-color: #007bff;
}

This will apply the primary button style from Bootstrap to all elements with the class “btn-primary” in your HTML file.
