title: Placeholder Mixin SCSS/CSS
body: <p>I'm trying to create a mixin for placeholders in sass. </p>
  
  <p>This is the mixin I've created.</p>
  
  <pre><code>@mixin placeholder ($css) {
    ::-webkit-input-placeholder {$css}
    :-moz-placeholder           {$css}
    ::-moz-placeholder          {$css}
    :-ms-input-placeholder      {$css}  
  }
  </code></pre>
  
  <p>This is how I'd like to include the mixin:</p>
  
  <pre><code>@include placeholder(font-style:italic; color: white; font-weight:100;);
  </code></pre>
  
  <p>Obviously this isn't going to work because of all the colons and semi-colons that's being passed through to the mixin, but... I'd really like to just input static css and pass it through exactly like the above function. </p>
  
  <p>Is this possible? </p>
