# Overview

> Understand the available liquid tags

Tags are used to add dynamic content to your theme. They allow you to insert variables, conditionals, and other elements into your templates.

## Usage

Tags are wrapped with curly brace percentage delimiters `{% %}`. The text within the delimiters doesn't produce visible output when rendered.

In the example below, we check if certificates are enabled for a course. If `certificate_enabled` returns true, then we show a message indicating certificates are available. Otherwise, we show that certificates are not available.

<Columns cols={2}>
  <CodeGroup>
    ```liquid Code theme={null}
    {% if all_courses["my-course"].certificate_enabled %}
      Certificates are available for this course!
    {% else %}
      Certificates are not available for this course.
    {% endif %}
    ```

    ```json Data theme={null}
    // Just an example initial data, the data is not real
    {
      "all_courses": {
        "my-course": {
          "certificate_enabled": true
        }
      }
    }
    ```
  </CodeGroup>

  <CodeGroup>
    ```liquid Output theme={null}
    Certificates are available for this course!
    ```
  </CodeGroup>
</Columns>
