# Bold
Renders text in **bold** text weight. If you pass `<strong>`, or `<b>` tags, or text with inline `style` attributes setting the `font-weight` CSS rule in the editor's initial content, they will be rendered accordingly.

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

| bold | none | Mark text as bold. |

#### Keybindings
