UI Components

Whether it’s used for navigation, actions, or form submissions, the button component allows users to interact with apps clearly and intuitively.

Introduction

The Button component is a fundamental element of any user interface and plays a crucial role in the GoodBarber design system. Whether it's used for navigation, actions, or form submissions, the Button component allows users to interact with your app in a clear and intuitive way.

In the GoodBarber design system, we've put a lot of thought into the design and functionality of the Button component to ensure that it is consistent and easy to use across all devices and platforms. The component is available in different styles and can be customized to match the overall design of your app.

Anatomy

Most of the time, the length of the buttons is dynamic according to the displayed text. Exceptionally, it will be constrained by the layout, as shown here.

The button component comes in 3 sizes: Small, Medium and Large.
