Centering textarea placeholder text in Safari

问题:

I want to center the placeholder text for my textareas. The code below works fine in Chrome and IE, but is left-aligned in Safari:

::-webkit-input-placeholder {
text-align:center;
}

:-moz-placeholder {
text-align:center;
}

How can I get it centered in Safari (preferably only using CSS)?

I made a simple solution that works on Safari 5+ and all other browser you can check it at: http://jsfiddle.net/joaorito/RqUJL

HTML

<div class="center_area">
<ul class="V_align">
    <li class="V_cell">
        <div class="V_element">Maecenas sed diam eget risus varius blandit sit amet non magna.</div>
    </li>
</ul></div>

CSS

.center_area
  {
  font-size: 16px;
  width: 300px;
  height: 300px;
  border: 5px solid black;
  } 

.center_area ul
  {
  margin: 0;
  padding: 0;
  list-style: none;
  background-color: red;
  height: 100%;
  width: 100%;
  }

.center_area ul li
  {
  color: #FFF;
  font-size: 1.500em;
  line-height: 28px;
  }

.center_area  ul li div
  {
  background-color: green;
  padding: 10px;
  text-align: center;
  }

.center_area .V_align
  {
  display: table;
  overflow: hidden;
  }

.center_area .V_align .V_cell
  {
  display: table-cell;
  vertical-align: middle;
  width: 100%;
  margin: 0 auto;
  }

.center_area .V_align .V_cell .V_element
  {
  display: block;
  }

This problem is specific to Safari 5.0 and Safari 5.1 + Win7 - as far as tests done by others are concerned.

Andrew M said it's working on Safari 6.0, 5.1 and Firefox 11 - both in Windows (no version mentioned, perhaps not Win 7) - and Mac.

I just tested the code below on Safari 6.0.2, Chrome 24.0.1, Firefox 18.0.1, and can confirm it's working. Doesn't work on Opera 12.10. All tested on OSX Lion. http://jsfiddle.net/dreamyguy/ZzdPH/

HTML

<input type="text" placeholder="Lorem ipsum" />

CSS

input { width: 200px; }
::-webkit-input-placeholder {
    text-align:center;
}
:-moz-placeholder {
    text-align:center;
}
:-ms-input-placeholder {
    text-align:center;
}

Maybe you should edit this question and make it specific to Safari version 5.0 and below, since it's a Safari specific question because the issue has been fixed in later versions.

input[type=textarea]

  line-height: 1;

I came across this issue where in I had to center align the placeholder but text-align: center didn't work on SAFARI and after many trials I came across a solution, which will not guarantee the exact center but can suffice the requirement.

Solution => Use text-indent

input{
    height:40px;
   width:190px;
   text-indent:60px;
}

If you want to put a placeholder into the center of a textarea you need to set the textareas height and set the line-height to the placeholders height as well as text-align center. Here are all of the available methods so far.

textarea {
    min-height: 60px;
}

textarea::-webkit-input-placeholder,  {
   text-align: center;
   line-height: 60px; // Input Height
}

textarea:-moz-placeholder { /* Firefox 18- */
   text-align: center;
   line-height: 60px; // Input Height
}

textarea::-moz-placeholder {  /* Firefox 19+ */
   text-align: center;
   line-height: 60px; // Input Height
}

textarea:-ms-input-placeholder {  
   text-align: center;
   line-height: 60px; // Input Height
}
