Use this extension to render text in **bold**. If you pass `<strong>`, `<b>` tags, or text with inline `style` attributes setting the `font-weight` CSS rule in the editor’s initial content, they all will be rendered accordingly.

Type `**two asterisks**` or `__two underlines__` and it will magically transform to **bold** text while you type.

::: warning Restrictions
The extension will generate the corresponding `<strong>` HTML tags when reading contents of the `Editor` instance. All text marked bold, regardless of the method will be normalized to `<strong>` HTML tags.
