Microsoft Adaptive Card - Column Size - botframework

Question

Does anyone know what is a proper value to set for column size for adaptive card ?
Schema (http://adaptivecards.io/explorer/#Column) says
"auto", "stretch", or a number representing relative width of the
column in the column Set (Default:Auto)
but actually I've tried number, percentage, px, pt but none is working.
Thanks

If you have a look to this sample: http://adaptivecards.io/visualizer/?card=/samples/cards/Input%20Form.json
You will see that the format is a basic number:
{
"$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
"type": "AdaptiveCard",
"version": "0.5",
"body": [
{
"type": "ColumnSet",
"columns": [
{
"type": "Column",
"size": 2,
"items": [
{
"type": "TextBlock",
"text": "Tell us about yourself...",
"weight": "bolder",
"size": "large"
},
{
"type": "TextBlock",
"text": "We just need a few more details to get you booked for the trip of a lifetime!",
"isSubtle": true,
"wrap": true
},
{
"type": "TextBlock",
"text": "Don't worry, we'll never share or sell your information.",
"isSubtle": true,
"wrap": true,
"size": "small"
},
{
"type": "TextBlock",
"text": "Your name",
"wrap": true
},
{
"type": "Input.Text",
"id": "myName",
"placeholder": "Last, First"
},
{
"type": "TextBlock",
"text": "Your email",
"wrap": true
},
{
"type": "Input.Text",
"id": "myEmail",
"placeholder": "youremail#example.com",
"style": "email"
},
{
"type": "TextBlock",
"text": "Phone Number"
},
{
"type": "Input.Text",
"id": "myTel",
"placeholder": "xxx.xxx.xxxx",
"style": "tel"
}
]
},
{
"type": "Column",
"size": 1,
"items": [
{
"type": "Image",
"url": "https://upload.wikimedia.org/wikipedia/commons/b/b2/Diver_Silhouette%2C_Great_Barrier_Reef.jpg",
"size": "auto"
}
]
}
]
}
],
"actions": [
{
"type": "Action.Submit",
"title": "Submit"
}
]
}
It's working a bit like bootstrap; here your first column will get 2/3 = 2/(2+1) of the total width, and the second one 1 third (1/(2+1)).
