You can select the button you want by comparing the different buttons and the functionality of each in this post. Switches and checkboxes are each used for different purposes. Optimal use of them causes the user to choose a more appropriate option. In this code, all buttons are in blue selection mode. These buttons also turn gray when inactive.
