@markand to give you an idea of how shortcodes _might_ help with your use case:

Create the following at `layouts/shortcodes/alert.html`:

```auto
<div class="alert alert-{{.Get 0}}" role="alert">{{.Get 1}}</div>

```

Then in your markdown files you can call this shortcode anywhere you want within the content/body copy for the file:

```markdown
{{< alert "info" "This is a notice." >}}

```

This should then render as follows:

```auto
<div class="alert alert-info">This is a notice.</div>

```

If you want the added ability to write the copy for the alert in markdown, you can use the alternate shortcode syntax at `layouts/shortcodes/alert.html`

```auto
<div class="alert alert-{{.Get 0}}" role="alert">{{- .Inner -}}</div>

```

But you would then have to call the shortcode using the `%`:

```markdown
{{% alert "info" %}}
This is a **notice**.
{{% /alert %}}

```

Which would render as…

```auto
<div class="alert alert-info" role="alert">This is a <strong>notice</strong>.</div>

```
