      <Modal.Header><em>publicPath</em> should be set to <em>/_next/static/</em></Modal.Header>

                Larger content should be still availble as a fallback
                to <em>fileLoader</em> but
                it should not polute <em>/.next/static/css</em> folder.
                You should see two images below.
                One, smaller, loaded as data url, and one, bigger, loaded
                via url.
              </p>
            </div>
            <div className='row'>
              <img src={SmallImage} />
              <p>
                A small image should be loaded as data url: <em>{SmallImage.substr(0, 100)}...</em>
              </p>
            </div>

            <div className='row'>
              <img src={LargeImage} />
              <p>
                A large image should be loaded as a url: <em>{LargeImage}</em>
              </p>
            </div>
            <p className='border'>
              You should also still be able to load regular css.
              This text should have border.
            </p>
          </div>
        </Modal.Description>
      </Modal.Content>
    </Modal>
