# Example: Contextual Example

CSS Reset can be used contextually by appyling CSS Reset to specific regions of the page.

## Contextual Usage

When CSS Reset is included in a page it applies rules to all HTML elements via type selectors like this: `h1 {margin:0;}`. The contextual version uses only descendent selectors like this: `.yui3-cssreset h1 {margin:0;}`. This means you can put that class value on a node in your document to choose which region(s) of your page CSS Reset will be applied to.

    <div class="yui3-cssreset">
        <p>Everything within this container will have CSS Reset applied.</p>
    </div>

Because CSS examples are susceptible to other CSS on the page, this example is only available in a new window at the above link.
