# accessibility.screenReaderSection.beforeChartFormat

Format for the screen reader information region before the chart. Supported HTML tags are `<h1-6>`, `<p>`, `<div>`, `<a>`, `<ul>`, `<ol>`, `<li>`, and `<button>`. Attributes are not supported, except for id on `<div>`, `<a>`, and `<button>`. Id is required on `<a>` and `<button>` in the format `<tag id="abcd">`. Numbers, lower- and uppercase letters, "-" and "#" are valid characters in IDs.

The headingTagName is an auto-detected heading (h1-h6) that corresponds to the heading level below the previous heading in the DOM.

Set to empty string to remove the region altogether.
