html - 如何让我的元素占用其 "max-width"规范的宽度？

Question

我正在尝试使用以下形式在屏幕上对齐输入

<form id="search-form" action="/events/search" accept-charset="UTF-8" method="get"><input name="utf8" type="hidden" value="✓">
<input type="text" name="first_name" id="first_name" value="Dave" placeholder="First Name">
<input type="text" name="last_name" id="last_name" value="" placeholder="Last Name">
<input type="text" name="event" id="event" value="" placeholder="Event">
<input alt="Search" type="image" src="http://www.racertracks.com/assets/magnifying-glass-0220f37269f90a370c3bb60229240f2ef2a4e15b335cd42e64563ba65e4f22e4.png"  class="search_button">
</form>

但是，除非屏幕很小(< 400 像素)，否则我不希望事情开始环绕。否则，我希望所有内容都占据我屏幕的 100%，最多 1000 像素。所以我尝试添加这个 CSS

@media (max-width: 1000px) {
  #search-form {
    -ms-flex-wrap: wrap; 
        flex-wrap: wrap;
  }

  #first_name {
    width: 50%;
    margin: 0;
  }

  #last_name {
    width: calc(50% - 1px);
    margin-left: 1px;
  } 

  #first_name, #last_name {
    margin-bottom: 1px;
  }

  #event {
    width: calc(100% - 20px);
    margin: 0;
  }
}

这是说明问题的 Fiddle -- https://jsfiddle.net/7h62z3tw/2/。除非屏幕很小，否则我该如何调整以使所有内容保持在同一条线上？

我想这就是您要找的。我添加了一些额外的 css 以使媒体屏幕 <400px 和普通寡妇看起来都不错。我还在添加和更改的 css 部分注释掉了。 Live ON Fiddle
