# HTMS Files

HTMS Files are a file format that contains samples

These files can have any extension but we recommend one of the following:

* .htms
* .html
* .xml

### Sample syntax:

```html
<sample name="Sample">
  HTML Content
</sample>
```

Sample name should be treated as an id, and having multiple with the same name may cause issues

### Static vars

To add [static vars](/concepts/static-vars.md) in the html content include

${VarName}

```html
<sample name="Greeting">
  Hello, ${name}
</sample>
```
