Can you show an example of how you would use Bootstrap's built-in CSS classes to style a button?

Yes, here's an example of how you would use Bootstrap's built-in CSS classes to style a button:

<button class="btn btn-primary">Primary</button>

In this example, the .btn class is used to apply the default button styling, and the .btn-primary class is used to give the button a primary color. Bootstrap includes several other button classes, such as:

• .btn-secondary
• .btn-success
• .btn-danger
• .btn-warning
• .btn-info
• .btn-light
• .btn-dark
• .btn-link

You can also use the .btn-* to change the button's color, and the .btn-outline-* to apply an outline style to the button.

Additionally, you can use different sizes for your buttons by using the classes .btn-lg, .btn-sm, .btn-block and .btn-group-* to create a group of buttons

Here's an example:

<button class="btn btn-primary btn-lg">Large Primary</button> <button class="btn btn-secondary btn-sm">Small Secondary</button> <button class="btn btn-danger btn-block">Block Danger</button> <div class="btn-group" role="group"> <button class="btn btn-primary">Button 1</button> <button class="btn btn-secondary">Button 2</button> <button class="btn btn-danger">Button 3</button> </div>

You can also use the .active, .disabled and .focus classes to create different states for the button. Please note that the above is just a small example of what you can do with Bootstrap's button classes, and you can customize and style your buttons even further using custom CSS or SASS variables.
