# Tag Hierarchy

## Content

The Spread, Sheet, and Column are the basic elements of tag hierarchy. The three tags are: `gc-spread-sheets`, `gc-worksheet`, and `gc-column`.

The following example displays the basic tag hierarchy:

```HTML
<gc-spread-sheets>
  <gc-worksheet>
    <gc-column></gc-column>
    ...
  </gc-worksheet>
  ...
</gc-spread-sheets>
```
