I'm trying to reduce the width of the TextField component :

Here is the render method:

  render() {

    return (

      <div>

          <div>

            <form onSubmit={this.handleSubmit}>

                <TextField

                  hintText="Email"

                  ref="email"

                /><br/>

                <TextField

                  hintText="Password"

                  type="password"

                  ref="password"

                /><br/>

              <button className="btn btn-success" onClick={this.loginCommand}><i className="fa fa-sign-in"/>{' '}Log In</button>

            </form>

          </div>

      }

      </div>

    );

  }

}
