title: Could not able to center align the text content within the mat-card-content using Flex-layout
body: <p>I am currently working on a layout where I'm not able to center align (<code>justify-content : center</code>). I am using Angular flex layout and material.
  Am I missing anything or I misunderstood flex-layout? </p>
  
  <pre><code>&lt;mat-card class="example-card mat-elevation-z" fxLayout="row wrap" fxLayoutAlign="center"&gt;
        &lt;mat-card-header&gt;
          &lt;mat-card-title&gt;
              &lt;h1 fxFlex fxFlex="100" fxFlexAlign="center"&gt;ALOE VERA For Pure &lt;span class="title-line"&gt;&lt;/span&gt;&lt;/h1&gt;
          &lt;/mat-card-title&gt;
        &lt;/mat-card-header&gt;
        &lt;mat-card-content fxLayout="row wrap" fxLayoutAlign="center"&gt;
          &lt;p fxFlex fxFlex="100" fxLayoutAlign="center"&gt;Aloe Vera is very famous for its herbal products. more than three thousand five hundred years, people have recognized the healing and moisturizing properties of the aloe vera plant.
