# Smarty Documentation
Smarty is a template engine for PHP, facilitating the separation of presentation (HTML/CSS) from application logic. 

It allows you to write **templates**, using **variables**, **modifiers**, **functions** and **comments**, like this:
```smarty
<h1>{$title|escape}</h1>

<p>
    The number of pixels is: {math equation="x * y" x=$height y=$width}.
</p>
```

When this template is rendered, with the value "Hello world" for the variable $title, 640 for $width, 
and 480 for $height, the result is:
```html
<h1>Hello world</h1>

<p>
    The number of pixels is: 307200.
</p>
```
