# Responsive design

To create a responsive app, the first containers you add to a screen must add up to 100% height, for example:

![](/files/-M-Cz_Q4YEFUwtzdjaR1)

You can change the dimensions of the container by selecting the container and clicking the style tab

![](/files/-M-DCfAIwEfuthh6mOiB)
