title: How to add padding or margin only to the layout container in Angular ngMaterial?
body: <p>When I add <code>layout-margin</code> or <code>layout-padding</code> to a layout container this adds margin/padding around each <code>flex</code> child element and to the container itself.</p>
  
  <p>Example:</p>
  
  <pre><code>&lt;div layout="row" layout-margin&gt;
    &lt;div flex&gt;Parent layout and this element have margins.&lt;/div&gt;
  &lt;/div&gt;
  </code></pre>

  <p>I want to add margins to the the container and not to the childrens of the container.</p>

  <p>Is there a predefined class in Material Design to add padding or margin to the layout container without adding them to the childrens inside the layout container?</p>
