# Basic Functional Template
A basic functional template file (`mastertemplate.bwmt`) without any layout or styling consists of the following mandatory template parts: `<% CommonScripts %>`, `<% Content %>`, `<% HiddenFormFields %>`, and `<% StartupScripts %>`. Most applications cannot function properly without `<% Navigation main %>`, `<% ButtonBarButtons left %>`, and `<% ButtonBarButtons right %>`.
Putting it all together, you will get something like the example below:
```html
My WEM Application
<% CommonScripts %>
<% Navigation main %>
<% ButtonBarButtons left %>
<% ButtonBarButtons right %>
<% StartupScripts %>
```
{% hint style="info" %}
Using the code above will give your WEM application a very basic retro appearance, as there are no layout or styles added to it.
{% endhint %}
### Postback
As shown in the basic template above, to perform a proper postback, the `<% Content %>` and `<% HiddenFormFields %>` should be placed inside a `
```
### Remarks
Refer to the WMT reference for more details about the template parts and additional elements that can be used in design templates.
