CSS styling placeholder text

问题

I am trying to style placeholder text, but I can't seem to select it. If my input is this:

<input id="search" class="search-query" placeholder="Placeholder text here" name="" value"">

How can I select the placeholder text in css for styling?

   color: red;  
}

   color: red;  
}
