Impresi\n\nImpresi is a Javascript library for creating beautiful slide presentations.\n\n[Demo](https://538mkz3prl.codesandbox.io)\n\n## Installation\n### Through CDN\n````\nhttps://unpkg.com/impresi\n````\n[Demo](https://codepen.io/richjava/pen/XGjQbd)\n### Through NPM\n```\nnpm i impresi --save\n````\n[Demo](https://codesandbox.io/s/538mkz3prl)\n\n## Usage\n### The Impresi instance\n\nEvery Impresi application starts by creating a new Impresi instance:\n\n````\nlet impresi = new Impresi(\"board\");\n````\n\nIn the above example, \"board\" is the ID of the HTML element acting as a container for the Impresi board, for example:\n\n````\n\u003cdiv id=\"board\"\u003e\u003c/div\u003e\n````\n\nThe easiest way to use Impresi is to pass a configuration object to the Impresi instance:\n\n````\n let config = {\n    resources: [\n      {\n        id: \"b1\",\n        type: \"background\",\n        options: {\n          \"backgroundColor\": \"#e6f7ea\"\n        }\n      },{\n        id: \"b1h1\",\n        type: \"heading\",\n        text: \"Hello Impresi\",\n        options: {\n          x: 37,\n          y: 20\n        }\n      }\n    ],\n    actions: [\n      { in: [\"b1\", \"b1h1\"] }\n    ]\n  };\n\n  let impresi = new Impresi(\"board\", config);\n  impresi.start();\n````\n\nThe same can be achieved by chaining methods together, like so:\n\n````\nlet b1 = impresi.createBackground(options: {\n          \"backgroundColor\": \"#e6f7ea\"\n  });\n let b1h1 = impresi.createHeading(\n    \"A heading\",\n    {\n      x: 37,\n      y: 20\n    }\n  );\nimpresi\n    .addActions({ in: [b1, b1h1] });\nimpresi.start();\n````\n\n## Methods\n### createBackground\n````\ncreateBackground([options]) :
