CSS Question

Bootstrap Form Validation - color doesn't change

I followed this link http://twitterbootstrap.org/bootstrap-form-validation/ to build a form validation that consist of name and username at my localhost.

The problem I am facing is that When I clicked sign up when both fields are empty, the error "The field is required" displays but when I had input a name or username, it displays "OK!" in red even though I assigned the css to be green under label.success.

Please help.

Css

body {
width:100%;
height:100%;
}


html {
width: 100%;
height: 100%;

}

@import url("assets/css/bootstrap.min.css");
@import url("assets/css/bootstrap-responsive.min.css");


label.valid {
font-weight: bold;
color: green;
padding: 2px 8px;
margin-top: 2px;
}
label.error {
font-weight: bold;
color: red;
padding: 2px 8px;
margin-top: 2px;
}

Answer

You should use "has-success", "has-warning" or "has-error" classes on the form input wrapper

<div class="form-group has-success">
    <label class="control-label" for="inputSuccess1">Input with success</label>
    <input type="text" class="form-control" id="inputSuccess1" aria-describedby="helpBlock2">
    <span id="helpBlock2" class="help-block">A block of help text that breaks onto a new line and may extend beyond one line.</span>
</div>
<div class="form-group has-warning">
    <label class="control-label" for="inputWarning1">Input with warning</label>
    <input type="text" class="form-control" id="inputWarning1">
</div>
<div class="form-group has-error">
    <label class="control-label" for="inputError1">Input with error</label>
    <input type="text" class="form-control" id="inputError1">
</div>

By the way, using !important is not a good idea and currently it is frowned upon. If you want to change standard Bootstrap color, you should compile from a SASS or LESS version. They also have mixins that allow you to apply bootstrap styles on custom HTML-classes.
