I am using an app that outputs HTML and it only supports adding custom classes.

So given,

```
<div class="my-button data-featherlight-hash-mylightbox data-jarallax data-speed-num-zero-point-two">Content</div>

```

how can I change it to

```
<div class="my-button" data-featherlight="#mylightbox" data-jarallax data-speed="0.2">Content</div>

```

using jQuery?

Any help is appreciated.
