fail to change placeholder color with Bootstrap 3
Two questions:
I am trying to make the placeholder text white. But it doesn't work. I am using Bootstrap 3. JSFiddle demo
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; }
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.
There was an issue posted here about this: https://github.com/twbs/bootstrap/issues/14107
The issue was solved by this commit: https://github.com/twbs/bootstrap/commit/bd292ca3b89da982abf34473318c77ace3417fb5
The solution therefore is to override it back to #999 and not white as suggested (and also overriding all bootstraps styles, not just for webkit-styles):
.form-control::-moz-placeholder {
color: #999;
}
.form-control:-ms-input-placeholder {
color: #999;
}
.form-control::-webkit-input-placeholder {
color: #999;
}
A Possible Gotcha
Recommended Sanity Check - Make sure to add the form-control class to your inputs.
If you have bootstrap css loaded on your page, but your inputs don't have the
class="form-control" then placeholder CSS selector won't apply to them.
Example markup from the docs:
I know this didn't apply to the OP's markup but as I missed this at first and spent a little bit of effort trying to debug it, I'm posting this answer to help others.
