Replacing CSS classes in ReactJS

I am looking to customize the CSS of certain React classes in order to achieve a specific look for an input in a form. My goal is to have the input displayed as a straight line without any background color. Here is the CSS code I have been using:

.text-line {
background-color: transparent;
color: #eeeeee;
outline: none;
outline-style: none;
border-top: none;
border-left: none;
border-right: none;
border-bottom: solid #eeeeee 1px;
padding: 3px 10px;
}

I have attempted to add inline CSS and create custom classes, but neither method seems to be working as intended.

<Form>
    <Form.Group controlId="formBasicEmail">
        <Form.Label>Phone number, email or username</Form.Label>
        <Form.Control type="email" placeholder="Enter email" onChange={this.handleUsernameChange} value={this.state.username} />
    </Form.Group>
</Form>

Is there a way to cleanly override React's default CSS classes? I have also imported react-bootstrap using npm.

Answer №1

As stated in the official documentation, the process of adding a CSS class (referred to as className in React) is demonstrated below:

<Form>
  <Form.Group controlId="formBasicEmail">
    <Form.Label>Email address</Form.Label>
    <Form.Control type="email" placeholder="Enter email" />
    <Form.Text className="text-muted">
      We'll never share your email with anyone else.
    </Form.Text>
  </Form.Group>
</Form>

Make sure to import the CSS file using the following code:

import "example.css";
