Usage

React Card Stack exports an object with two components. These are CardStack and Card. The CardStack component is responsible for holding the state of it's child Card components. However, this is abstracted away which makes using the component a whole deal simpler. Note: there must be at least two instances of Card as children of CardStack, otherwise the component will throw an error.

An example use of React Card Stack looks like:

import { CardStack, Card } from 'react-cardstack';

<CardStack
	height={500}
	width={400}
	background='#f8f8f8'
	hoverOffset={25}>

	<Card background='#2980B9'>
		<h1>Number 1</h1>
	</Card>

	<Card background='#27AE60'>
		<NumberTwo />
	</Card>

</CardStack>

The Card component wraps around the content you want to render for each card. You can render both elements or components inside Card.

Figuring out the Header Height

When all Card components are collapsed, the top of each card will be visible. This is basically the header of the Card component. To calculate what size the header will be simply divide the height passed to CardStack by the number of child Card components. In the example above, the header height for each card will be 500 / 2, which equals 250.

Options

CardStack

Property | Type | Default | Description ------------- | ------------- width | number | 350px | the width of the component height | number | 500px | the height of the component background | string | f8f8f8 | can be a hex, rgba, gradiant value or a url() hoverOffset | number | 30px | how far the card will shift up when being hovered

Card

Property | Type | Default | Description ------------- | ------------- background | string | undefined | can be a hex, rgba, gradiant value or a url() cardClicked | func | undefined | read below for description on how to use

cardClicked is a prop which can be passed to Card. It takes a function, acting as a callback, and will get invoked when a user clicks on the card in which you passed it to. For example, look below:

<Card
	background='#27AE60'
	cardClicked={this.handleCardClick.bind(this)}>
	<NumberTwo />
</Card>

// example of the function being bound
handleCardClick(cardSelected) {
	console.log(cardSelected);
}

When this.handleCardClick is invoked, it will receive the parameter cardSelected which will be a boolean describing whether there is currently a card selected or not.
