Question

I would like to know how can I define a post template and adding automatically the html layout when we are creating a post?

Do I have to use custom fields?

For example:

Post content:

   Title
    Description 1
    Description 2
    With links and social media

Html layout result:

   <h1 class="work-title">Title</h1>
       <div class="description">Description 1</div>
       <div class="description">Description 2</div>
       <div class="details">With links and social media</div>
    </div> 

Thanks

You could alter the output of the function the_content() by using (in functions.php) something like:

function alter_content($content) {
    // Alter the $content variable here
    return $content;
}

add_filter( 'the_content', 'alter_content', 6); 

Which will alter the content before the paragraphs are added. And if you don’t want paragraphs at all use:

remove_filter('the_content', 'wpautop');

Check out the codex page on apply_filters() for more info on the function.
