Making a responsive UI

In this section, we are going to learn how to make the UI we created previously adapt to different screen sizes. We are going to discuss the following concepts:

• Dynamic positioning and sizing
• Dynamic scaling
• Using relative positions

Let’s start by discussing how we can make the position and size of our objects adapt to the screen size.
