Imports
A very important built-in package for creating responsive layouts is the alexa-layouts
package. You import this package into the APL document as shown in the example below.
{
"type": "APL",
"version": "1.7",
"theme": "dark",
"import": [
{
"name": "alexa-layouts",
"version": "1.4.0"
}
],
"mainTemplate": {
"items": []
}
}
APL is a declarative language, so the order of the top-level document properties doesn't matter most of the time. You just need to maintain a logical structure.
