The `_gid` is the MD5 hashed version of the page's [`_path`](../path/). This
|
|
is useful in situations where a stable ID is needed that follows a certain
|
|
format. For instance it can come in useful when a ID is needed for a DOM
|
|
element.
|
|
|
|
## Example
|
|
|
|
```html+jinja
|
|
<body class="page-{{ this._gid }}">
|
|
...
|
|
</body>
|
|
```
