无法使两个联系人表单彼此居中

我一直在看CSS教程几个小时，尝试不同的方法来使它们内联，但我似乎做不到。

我目前正在学习UI/UX的最佳技术，并且正在使用Codeppen来获得灵感。

我正在尝试使这两种形式相互对齐。

任何帮助都会很棒。

我做了一个小提琴，它正确地呈现了联系形式，而不是地图的其他组件。

这是正确工作地图 UI 的代码笔。

您还可以使用以下代码片段：

var myCenter = new google.maps.LatLng(51.308742, -0.320850);
function initialize() {
  var mapProp = {
    center: myCenter,
    zoom: 12,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  };
  var map = new google.maps.Map(document.getElementById("map"), mapProp);
  var marker = new google.maps.Marker({
    position: myCenter,
  });
  marker.setMap(map);
}
google.maps.event.addDomListener(window, 'load', initialize);
