In this Bootstrap 4 buttons tutorial, you will learn how to create and modify buttons with the help of bootstrap 4. You can create a button by using the .btn class and by using some classes, you can style a button. These classes are as follows:
Bootstrap 4’s button styles are not only designed to be used with the <button> element, but they can also be applied to <input> and <a> elements.
You can also use the button styles to an <label> element when working with checkboxes and radio buttons.
If you need a button with outline or border then use .btn-outline class followed by desired style (for eg. btn-outline-primary).
Bootstrap offers different classes that allow changing the size of the button. You can make buttons larger or smaller by using the classes .btn-lg or .btn-sm.
Block Level Buttons:
You can create block-level buttons (buttons that cover the full width of the parent elements) by adding an extra class .btn-block to the buttons.
You can make a button or link active by using the .active class.
To disabled the button use disabled attribute with <button> element. And if the button created with <a> tag then it can be disabled by adding class .disabled.
By using spinner-* classes, you can add spinner to the button.
