How to remove complete header and footer from checkout/cart and afterwards all pages in magento

I have to remove complete header and footer from checkout/cart page to all onwards pages in magento 1.7. All I know that I need to add `<remove name="header"/>` in the "checkout.xml" file but whenever I'm trying to add that same line, Either nothing reflecting on front-end or a blank page appear on front-end.

In your local.xml use below code

To remove header and footer from **Cart** Page:

<checkout_cart_index>
<remove name="header"/>
<remove name="footer"/>
</checkout_cart_index>


To remove header and footer from **Checkout Onepage**:

<checkout_onepage_index>
<remove name="header"/>
<remove name="footer"/>
</checkout_onepage_index>

<checkout_cart_index translate="label">
<reference name="root">
<action method="setTemplate"><template>page/empty.phtml</template></action>
</reference>
</checkout_cart_index>

please goto page.xml for you template folder

<default translate="label" module="page">
<remove name="header"/>
<remove name="footer"/>

</default>
For only checkout Please goto checkout.xml

<checkout_cart_index translate="label">
<remove name="header"/>
<remove name="footer"/>
</checkout_cart_index>
<checkout_onepage_index translate="label">
<remove name="header"/>
<remove name="footer"/>
</checkout_onepage_index>

You may follow this steps:

step 1:

Go to app/design/frontend/yourtheme/layout/checkout.xml
add these two lines after this lines(


<checkout_cart_index translate="label">
<label>Shopping Cart</label>

)

<remove name="header"/>
<remove name="footer"/>

step 2:
If you are using any extension for checkout then
go to app/design/frontend/yourtheme/layout/your_extension_checkout.xml

add these two lines after this lines(

<onepagecheckout_index_index translate="label">
<label>One Page Checkout</label>

)

<remove name="header"/>
<remove name="footer"/>


otherwise go to your theme/layout/checkout.xml(same step1 file) and

add above two lines after this lines(`<checkout_onepage_index translate="label"> <label>One Page Checkout</label>`)



step 3: clearing your magento cache

You need to write in your XML file:

<remove name="header" />
<remove name="footer" />

In ur custom theme layout folder inside layout folder in ur local.xml copy this code for removing header and footer from checkout/cart page

`<checkout_cart_index>
<remove name="header"/>
<remove name="footer"/>
</checkout_cart_index>`

For removing checkout/onepage

`<checkout_onepage_index>
<remove name="header"/>
<remove name="footer"/>
</checkout_onepage_index>`

one thing remember copy this code after closing default tag in ur local.xml if u insert this code in default tag it will remove header nd footer from all pages
