title: Set css property using jQuery
body: <p>The goal is to amend all the <code>td</code> elements of class <code>mytable</code> to have css property <code>visibility:hidden</code>. the statement <code>$('.mytable td').css('visibility', 'hidden');</code> seems to have no effect, why?</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>$(document).ready(function () {
   $('.mytable td').css('visibility', 'hidden');
  });</code></pre>
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.mytable td {
      border:1px solid;
      visibility:inline;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;table class="mytable"&gt;
      &lt;tr&gt;
          &lt;td&gt;a&lt;/td&gt;
          &lt;td&gt;b&lt;/td&gt;
      &lt;/tr&gt;
  &lt;/table&gt;</code></pre>
  </div>
  </div>
  </p>
