# block
> Usage: `{{{block "section"}}}` and `{{#contentFor "section"}} content {{/contentFor}}`
***
`{{{block "block-name"}}}` is a helper for creating a placeholder within a custom handlebars template. Adding the helper along with a unique ID creates a slot within the template, which can be optionally filled when the template is inherited by another template file.
The `{{#contentFor "block-name"}}...{{/contentFor}}` helper is used to access and populate the block definitions within the template that’s being inherited. The inherited template is referenced with `{{!< template-name}}` at the top of the file. If the `contentFor` is not used then the block will be gracefully skipped.
### Example
```handlebars theme={"dark"}
{{{block "scripts"}}}
```
***
```handlebars theme={"dark"}
{{!< default}}
{{#contentFor "scripts"}}
{{/contentFor}}
```
## `{{{body}}}` helper
The `{{{body}}}` helper behaves in a similar fashion to a defined block helper, but doesn’t require a corresponding `contentFor` helper in the inheriting template file.
### `{{{body}}}` example
```handlebars theme={"dark"}
{{{body}}}
```
***
```handlebars theme={"dark"}
{{!< default}}
```
Inherited template files, files that contain `{{{block "block-name"}}}`, cannot be templates used directly by Ghost. `post.hbs`, `page.hbs` `index.hbs` can inherit other template files and used the `contentFor` helper but cannot contain block definitions. See our [theme structure documentation](/themes/structure/#templates) for more information.
