title: Show div even if empty
body: <p>I use Vuejs and have a component with div container which collapses if it's empty.</p>
  
  <pre><code>&lt;template&gt;
    &lt;div&gt;{{ content }}&lt;/div&gt;
  &lt;/template&gt;
  
  &lt;script&gt;
  export default {
    name: "myComponent",
    props: {
      content: String
    }
  };
  &lt;/script&gt;
  </code></pre>
  
  <p>When consuming this component I could go for</p>
  
  <pre><code>&lt;MyComponent content="text to show" /&gt;
  </code></pre>
  
  <p>but what if I want it to be empty? Then the div takes no space and collapses. I want to prevent it.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;!-- This one takes no space --&gt;
  &lt;div&gt;&lt;/div&gt;
  &lt;div&gt;This one takes space&lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>I thought about passing a unicode</p>

  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>div {
    background: red;
    margin: 20px;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div&gt;&amp;#10240;&lt;/div&gt;
  &lt;div&gt;This one takes space&lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>but the component does not convert it to a unicode character when receiving a string as a parameter.</p>
  
  <p>Is there a solution using CSS instead of a unicode character?</p>
  
  <p>I created a small example to show the current problem</p>
