🧱The container
For a design file to be Bravo-ready, you must add [containers]. These are components placed as a 2nd-level layer: inside ("nested" in) the app page and containing the different UI elements.
Containers have two main functions:
Wrap the individual UI elements (images, text, etc.) in the design.
Allow to create lists in the app page. Each container can be bound to API data that will make the container populate to a list in the app. To create a list, a placeholder list element needs to be created in the design, and wrapped in a container. How to connect the API data is further explained in the step 3 of Create your first app section.
How to create a container
You can find below how to create a container, depending on the design tool you use.
Container guidelines
Containers must:
Start the first container from the top of the app page component.
Include the padding of your design within the container.
They should not overlap one another *.
*Except for the top bar container. You can have a top bar container and another container starting from the top edge of the page.
If a container is <50% of the screen width, it will stack horizontally and then vertically down (when connected to API data to populate it into a list).
Where to add a container
Menu page
Create a container around the menu area + add the menu tag.
This page have a fixed top bar
Create a container frame around the top-bar area + add the top bar tag.
This page has a list design that will be populated with API data later
Create one container around the list item design. In case you have other non-list UI elements, create containers around them too.
This screen has a text box that will be populated with API data and can be different amount of text from your design
Create a container so that the text box is the bottom-most element in the container + add the flexo text tag. If there is anything else below, create another container below.
This screen has a design that needs to be the same aspect ratio across all device sizes (Ex: it must be full screen on all devices)
Create a container frame around the design that needs to maintain its ratio to designed screen size + add the aspect ratio to screen tag.
If you don't need to split the page with containers, create one container frame to enclose all the UI elements.
