title: How to remove bottom line of Header and top line of Footer in Native Base?
body: <p><a href="https://i.stack.imgur.com/pjQOK.png" rel="nofollow noreferrer">as the image can show it </a>, my app shows a line at the top of my Footer and at the bottom of my Header. Its seems a common thing in Native Base. I have checked out the native-base theme but I can´t find some to fix this error.</p>
  
  <p>Code:</p>
  
  <pre><code>import React, { Component } from 'react';
  import { Container, Content, Footer, FooterTab, Button, Icon, Text, Header, Title, Left, Right, Body, } from 'native-base';
  export default class FooterTabsExample extends Component {
    render() {
      return (
            &lt;Container&gt;
                &lt;Header&gt;
                  &lt;Left&gt;
                      &lt;Button transparent&gt;
                          &lt;Icon name='arrow-back' /&gt;
                      &lt;/Button&gt;
                  &lt;/Left&gt;
                  &lt;Body&gt;
                      &lt;Title&gt;Header&lt;/Title&gt;
                  &lt;/Body&gt;
                  &lt;Right&gt;
                      &lt;Button transparent&gt;
                          &lt;Icon name='menu' /&gt;
                      &lt;/Button&gt;
                  &lt;/Right&gt;
                &lt;/Header&gt;
                &lt;Content style={{backgroundColor:'black'}}/&gt;
  
                &lt;Footer &gt;
                    &lt;FooterTab&gt;
                        &lt;Button&gt;
                            &lt;Icon name="apps" /&gt;
                            &lt;Text&gt;Apps&lt;/Text&gt;
                        &lt;/Button&gt;
                        &lt;Button&gt;
                            &lt;Icon name="camera" /&gt;
                            &lt;Text&gt;Camera&lt;/Text&gt;
                        &lt;/Button&gt;
                        &lt;Button active&gt;
                            &lt;Icon active name="navigate" /&gt;
                            &lt;Text&gt;Navigate&lt;/Text&gt;
                        &lt;/Button&gt;
                        &lt;Button&gt;
                            &lt;Icon name="person" /&gt;
                            &lt;Text&gt;Contact&lt;/Text&gt;
                        &lt;/Button&gt;
                    &lt;/FooterTab&gt;
                &lt;/Footer&gt;
            &lt;/Container&gt;
      );
    }
  }
