Fixed HTML Structure

Is it possible to have a fixed structure for the HTML using CKEditor. For example, HTML5 placeholders are shown in editor as user hints so user know where to enter what content. Further, it should be possible that user shouldn't be able to change the structure.

An example structure may look like this and placeholder text is shown till user enters the text. 

<h1>Title Only</h1>

<section id="intro"> .... </section>

<section id="details"> ... </section>

<section id="footer"> ... </section>

As mentioned above, user shouldn't be able to change the structure/order of the sections.
