{{DefaultAPISidebar("DOM")}}

The **`ariaColIndexText`** property of the {{domxref("ElementInternals")}} interface reflects the value of the `aria-colindextext` attribute, which defines a human readable text alternative of aria-colindex.

> **Note:** Setting aria attributes on `ElementInternals` allows default semantics to be defined on a custom element. These may be overwritten by author-defined attributes, but ensure that default semantics are retained should the author delete those attributes, or fail to add them at all. For more information see the [Accessibility Object Model explainer](https://wicg.github.io/aom/explainer.html#default-semantics-for-custom-elements-via-the-elementinternals-object).

## Syntax

```js
let ariaColIndexText = ElementInternals.ariaColIndexText;
ElementInternals.ariaColIndexText = ariaColIndexText;
```

### Value

A {{domxref("DOMString")}}.

## Examples
