I started integrating jquery ui datepicker in my page.

I included the js files:

```
jquery-1.5.1.js
jquery.ui.core.js
jquery.ui.widget.js
jquery.ui.datepicker.js

```

and CSS Files:

```
jquery.ui.datepicker.css

```

But it resulted out datepicker without the background...

what am i missing on it?

After i manually add : 
`.ui-datepicker{background-color: silver;}`

it shows like:
