fail to change placeholder color with Bootstrap 3

Question

Two questions:

1. I am trying to make the placeholder text white. But it doesn't work. I am using Bootstrap 3. JSFiddle demo

2. Another question is how do I change placeholder color not globally. That is, I have multiple fields, I want only one field to have white placeholder, all the others remain in default color.

Thanks in advance.

html:

<form id="search-form" class="navbar-form navbar-left" role="search">
    <div class="">
        <div class="right-inner-addon"> <i class="icon-search search-submit"></i>
            <input type="search" class="form-control" placeholder="search" />
        </div>
    </div>
</form>

css:

.right-inner-addon {
    position: relative;
}
.right-inner-addon input {
    padding-right: 30px;
    background-color:#303030;
    font-size: 13px;
    color:white;

}
.right-inner-addon i {
    position: absolute;
    right: 0px;
    padding: 10px 12px;
    /*  pointer-events: none; */
    cursor: pointer;
    color:white;
}


/* do not group these rules*/
::-webkit-input-placeholder { color: white; }
FF 4-18 
:-moz-placeholder           { color: white; }
 FF 19+
::-moz-placeholder          { color: white; }
 IE 10+
:-ms-input-placeholder      { color: white; } 

Answer 1

Assign the placeholder to a class selector like this:

.form-control::-webkit-input-placeholder { color: white; }  /* WebKit, Blink, Edge */
.form-control:-moz-placeholder { color: white; }  /* Mozilla Firefox 4 to 18 */
.form-control::-moz-placeholder { color: white; }  /* Mozilla Firefox 19+ */
.form-control:-ms-input-placeholder { color: white; }  /* Internet Explorer 10-11 */
.form-control::-ms-input-placeholder { color: white; }  /* Microsoft Edge */

It will work then since a stronger selector was probably overriding your global. I'm on a tablet so i cant inspect and confirm which stronger selector it was :) But it does work I tried it in your fiddle.

This also answers your second question. By assigning it to a class or id and giving an input only that class you can control what inputs to style.
