CSS - :-ms-input-placeholder

The following example highlights the Branch and ID code fields with a custom style. The placeholder text is displayed with the specified style until the field has focus, meaning that the field can be typed into. When the field has focus, it returns to the normal style of the input field and the placeholder text disappears.

HTML

<form id="test"> 
  <p><label>Enter Student Name: <input id="name" placeholder="Student Name"/></label></p>
  <p><label>Enter Student Branch: <input id="branch" placeholder="Student Branch" /></label></p>
  <p><label>Enter Student ID: <input type="num" pattern="[0-9]{8}" title="8 digit ID" id="sid" class="studentid" placeholder="8 digit id" /></label></p> 
  <input type="submit" /> 
</form>

CSS

input { 
   background-color:#E8E8E8; 
   color:black; } 
/* placeholder only style */ 
input.studentid:-ms-input-placeholder { 
   font-style:italic; 
   color: red; 
   background-color: yellow; 
}
