I know what you mean.

However Headings are Block-level elements. <hX> elements aren't just about setting font size, color, they add structure to your content.

When you apply heading directly, the whole paragraph will become the heading of the page.

<div>

If you just want to change the ABB Automation to heading tag, the fist step we should do is changing the page structure.

Select the ABB Automation, and click insert paragraph button, now you can apply any block-level elements.

Hope it helps.

Let me know if you have any further questions.
