无法使用Bootstrap 3更改占位符颜色 [英] fail to change placeholder color with Bootstrap 3

问题描述

两个问题：

1. 我试图使占位符文本为白色。但它不工作。我使用Bootstrap 3. JSFiddle演示

另一个问题是如何在全局范围内更改占位符颜色。也就是说，我有多个字段，我只想要一个字段有白色占位符，所有其他字段保持默认颜色。

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.

提前感谢。

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; } 

推荐答案

将占位符分配给类选择器，

Assign the placeholder to a class selector like this:

.form-control::-webkit-input-placeholder { color: white; }
.form-control:-moz-placeholder { color: white; }
.form-control::-moz-placeholder { color: white; }
.form-control:-ms-input-placeholder { color: white; }

这将工作，因为一个更强的选择器可能覆盖你的全局。我在一个平板电脑，所以我不能检查和确认哪个更强的选择器它是:)但它的工作我尝试它在你的小提琴。

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.

这也回答了你的第二题。通过将它分配给一个类或id，并且只给该类提供一个输入，你可以控制什么样的输入。

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.
