HTML Tips

DataSet Property are Case-Insensitive

HTML is case-insensitive, but often forgotten that dataset property name either. such as:

<div data-foobar data-fooBar data-foo-bar><div>

data-foobar data-fooBar are the same thing, map to dom dataset API of .dataset.foobar property.

To create a camel case dataset property, use dash separated, such as foo-bar as `dataset.fooBar.

If double dash foo--bar used, map to dataset['foo-Bar'].
