# How to use the Element Attribute feature?

This piece of code will allow you to change the behavior of any HTML element. Please use it at your own risk and only if you're a dev. Put it in some \<div> and it will work. See an example below

```
<div data-cowlendar-btn="643ab6bc1000de7373a6a16b-44883814416694">Custom element</div>
```
