title: Change css on Multi language website
body: <p>I made a double language website using angular 4 and <code>ngx-translate</code>. one <code>rtl</code> and the other one <code>ltr</code>. How can I change the direction of text and text alignment on language change? </p>
  
  <p>I cant use because I don't know how to change this attribute in angular.</p>
  
  <pre><code>html:lang(en) h1{
      text-align: left;
  }
  </code></pre>
  
  <p>Any way I can target each language in <code>style.css</code>?? </p>
