Usage

Defining a layout.json file

A layout .json file should follow the following syntax:

• The json file contains one json object.
• First level of the json object should have key root.
• For (key, value) pairs in other levels, the keys should abide by the following conventions:
  • percentage: percentage of the children <div>'s height or width with respect to its parent's.
  • layout type: defines a column layout or a row layout (column layouts will be inside a flex container). If r is specified, the percentage is the relative height; if c is specified, the percentage is the relative width.
  • id (optional): used to prevent duplicate keys in the json object.

key = percentage + layout type + id

• For keys in the same level, their layout types should be the same.
• For keys in the same level, it is better that their percentage add up to 100.
• If no more <div>s are to be splitted, set the value of the key to be null.

Sample layout.json file

{
    "root":{
        "70r":{
            "10c": null,
            "20c": {
                "10r": null,
                "90r": null
            },
            "70c": {
                "50r1": null,
                "50r2": {
                    "20c1": null,
                    "20c2": null,
                    "60c": null
                }
            }
        },
        "30r": {
            "80c": null,
            "20c": null
        }
    }
}

Sample index.html output

Here <div> blocks are randomly colored for the sake of clarity with the --colored flag specified.

Plain borders surrounding blocks with --border flag specified.

The above picture shows how the json file syntax associates with actual layout generated.

Generate html and css

griddy <name of the layout file>

An index.html file and a styles.css file will be generated in the current working directory. You can simply plugin the generated grid <div> (top-level <div> of class root with style width: 100%; height:100%) anywhere in your existing code.

Command-line arguments

For example,

griddy layout.json --border --show
