Below I have extended the Ccreated an Html helper to havewith methods thato help me locate directories of my assets dynamically. Such assets may include CSS, JavaScript and images. ```php <?php class Html extends CHtml
{
/**```php
<?php
echo CHtml::cssFile(Html::cssUrl('reset.css')); echo CHtml::cssFile(Html::cssUrl('typography.css')); echo CHtml::cssFile(Html::cssUrl('main.css')); echo CHtml::cssFile(Html::cssUrl('form.css')); ?> ``` This is much cleaner and shorter then prefixing the URLs manually. Also, if you ever wish to move the directory of some sort of asset, all you need to do is modify the corresponding method in Html.
 
 
You may note that in the above example, `Html` does not *have* to extend `CHtml`.  Neither do you have to name the class `Html`.  It's all personal preference.
