如何在引导程序中将表单输入标签和段落的文本颜色更改为白色

Question

Hie, I have a signup form on top of a full-screen video. I am using Bootstrap and I don't know how to get white text color for my form labels and the paragraph beside the form. I am still very new to Bootstrap I have so far only found colors, the paragraph class colors conflict with my design, I just need to get white but I don't know how to do it. I realize that this may be all to simple and I apologize and I apologize in advance if that is the case. Any help will be greatly appreciated.

Here is my code:

<div class="container-fluid">
<section class="container">
    <div class="container-page">                
        <div class="col-md-6">
            <h3 class="dark-grey">Registration</h3>

            <div class="form-group col-lg-12">
                <label>Username</label>
                <input type="" name="" class="form-control" id="" value="">
            </div>

            <div class="form-group col-lg-6">
                <label>Password</label>
                <input type="password" name="" class="form-control" id="" value="">
            </div>

            <div class="form-group col-lg-6">
                <label>Repeat Password</label>
                <input type="password" name="" class="form-control" id="" value="">
            </div>

            <div class="form-group col-lg-6">
                <label>Email Address</label>
                <input type="" name="" class="form-control" id="" value="">
            </div>

            <div class="form-group col-lg-6">
                <label>Repeat Email Address</label>
                <input type="" name="" class="form-control" id="" value="">
            </div>          

            <div class="col-sm-6">
                <input type="checkbox" class="checkbox" />Sigh up for our newsletter
            </div>

            <div class="col-sm-6">
                <input type="checkbox" class="checkbox" />Send notifications to this email
            </div>              

        </div>

        <div class="col-md-6">
            <h3 class="dark-grey">Terms and Conditions</h3>
            <p>
                By clicking on "Register" you agree to The Company's' Terms and Conditions
            </p>

Answer 1

you can apply white color to label and p tag as below

.form-group label, p{
  color: #fff;
}

it it doesnt work use !important

.form-group label, p{
  color: #fff!important;
}

Answer 2

This should be as simple as:

body {
  background-color: black;
}
p,label {
  color: white;
}

Answer 3

This should do it:

form, input, label, p {
    color: white !important;
}

In most cases when using bootstrap, you will need !important to override the existing bootstrap css style.
