Step 1 : Creat static block
<div><h3>Static Block</h3></div>

Step 2 : 
Next, we will create a new CMS page that will contain the created static block which will be added through 
Layout Update XML on Designs tab, along with a header and one paragraph. For this example, we’ll use 1 column layout for 
all CMS pages.
<reference name="root">
        <block type="cms/block" name="banner">
            <action method="setBlockId"><block_id>static-block-id</block_id></action>

Step 3: add this into page
 <?php echo $this->getChildHtml('banner') ?>
