title: ReactJS: How can I align form <Field>'s <input> and <button> and <h1> in a row inside a <div>?
body: <p>I have <code>&lt;button/&gt;</code> and <code>&lt;input/&gt;</code> inside a container. How can I get them to align in the same row, next to each other, and in the middle of the container vertically?</p>
  
  <p>This is what I have so far: </p>

  <p>The top black portion is a navigation bar and I want to side-by-side align them in a row, next to each other from left to right, and align them vertically in the middle of the navigation bar:</p>
  
  <p><strong>PLEASE TAKE A LOOK AT EDIT AT THE BOTTOM FOR UPDATED CODE</strong> </p>
  
  <pre><code>       import { Field, reduxForm } from 'redux-form';
  
         const form = reduxForm({
           form: 'register'
         });
  
         ...
  
    &lt;div id="wrapper"&gt;
      &lt;header&gt;
         &lt;div className="container"&gt;
          &lt;h1&gt;
            TESTING
          &lt;/h1&gt;
          &lt;form&gt;
              &lt;Field
                name="email"
                className="form-control"
                component={
                    &lt;div&gt;
                      &lt;input
                        className="form-control"
                        id="input-field"
                        placeholder='Enter Email'
                      /&gt;
                   &lt;/div&gt;
                }
                type="text"
              /&gt;
              &lt;button
                type="submit"
                className="btn"
              &gt;
                Register
              &lt;/button&gt;
            &lt;/form&gt;
          &lt;/div&gt;
      &lt;/header&gt;
    &lt;/div&gt;
  </code></pre>
  
  <p>And CSS stylesheet:</p>
  
  <pre><code>#wrapper {
    width: 100%;
    margin: 0 auto;
  }
  
  .container {
    display: flex;
    justify-content: center;
  }
  
  header {
    width: 100%;
    height: 85px;
    overflow: hidden;
    position: fixed;
    top: 0;
    left: 0;
    z-index: 999;
    background-color: black;
    }
  header h1#logo {
    display: inline-block;
    height: 85px;
    line-height: 85px;
    float: left;
    font-size: 25px;
    color: purple;
    font-weight: 500;
  }
  
  #input-field {
    background-color: rgba(255,255,255,0.1);
    border-radius: 5px;
    width: 150px;
    height: 40px;
    padding: 5px;
  }
  </code></pre>
  
  <p><strong>EDIT</strong></p>
  
  <p>Decided to take the Form out but CSS stay the same. How can I flex align the following to achieve what I originally wanted (Would like to have the h1 to the left and text field + button to the right? </p>
  
  <pre><code>  &lt;div id="wrapper"&gt;
      &lt;header&gt;
         &lt;div className="container"&gt;
            &lt;h1&gt;
              TESTING
            &lt;/h1&gt;
            &lt;input
              className="form-control"
              id="input-field"
              placeholder='Enter Email'
            /&gt;
            &lt;button
              type="submit"
              className="btn"
            &gt;
              Register
            &lt;/button&gt;
        &lt;/div&gt;
      &lt;/header&gt;
    &lt;/div&gt;
