对齐div是并排的吗？

Question

我正在为一个旅游网站创建这个界面，我正在并排对齐两个输入，但它们没有正确对齐。我最关心的是出发和返回输入。返回输入和标签与出发输入和标签不对齐。

有人可以检查我的代码并提出解决方案吗？这可能是我的愿景，但如果你能帮助我，我将非常感激。

Answer 1

在

<div id="flights-data">

中进行以下更改：

    <label for="fly-from">Flying from</label><br>
    <input type="text" id="fly-from" value="Departure city or Airport">
    <label for="fly-to">Flying to</label><br>
    <input type="text" id="fly-to" value="Departure city or Airport"><br>
    <div id="departing-block">
      <div style="display: inline-block;">
      <label for="Departure">Departing Flight</label><br>
      <input type="text" id="flight-departure" value="Pick-a-date"> 
      </div>

      <div style="display: inline-block;">
      <label id="return" for="Return">Returning</label><br>
      <input type="text" id="flight-return" value="Pick-a-date">    
      </div>
      
     
    </div>
    <label for="passengers">Passengers</label><br>
    <input type="text" id="passengers" value="1 Adult 0 Children">
    <div id="find-a-flight">Find a Flight</div>
  </div>

这将正确并排对齐两个输入。我查过了。
