Equalizer

Equalizer is an es6 Class which can be used to easily match the height of multiple elements using names to isolate matching groups.

Note: version 1.0.0 has breaking changes. Please update your code, or lock your version to 0.1.9 to avoid errors

    for (let index = 0; index < equalizers.length; index++) {
        const container = equalizers[index];

        new Equalizer({
            container,
            identifiers: container.getAttribute('data-equalize'),
            rows: true,
        });
    }
});

Usage

When you create a new Equalizer, you need to pass 3 arguments

Argument	Description
container	The container is the element that is holding the items we want to resize
identifiers	The identifiers is a string of comma separated values that are used to match the elements we want to resize. The identifiers can be a selector, or a comma separated list of selectors. The container will be searched for child elements that have a matching identifier within a data-equalize-watch attribute.
rows	The rows is a boolean that determines whether we want to resize the elements in rows or not. If not all elements will be the same height regardless of their position on the page.
throttle	The throttle is a number that determines how often the equalizer will check for changes per update(). The default is 0.
debounce	The debounce is a number that determines how long the equalizer will wait after the last resize event before updating. The default is 100.
mutations	Settings that will be injected into the MutationObserver. The default is { childList: true, subtree: false }

## Events

You can call an `on` method on the Equalizer instance to listen for events.

```es6
equalizer.on('resize', () => {
    console.log('resize');
});

Event	Description
resize	This event is fired when the Equalizer is resized.
beforeResize	This event is fired before the Equalizer is resized
update	This event is fired when the Equalizer is updated.
beforeUpdate	This event is fired before the Equalizer is updated.
