固定宽度项左侧的动态全宽容器内的全宽输入

Question

在标题中很难解释......但基本上我需要右边的项目（搜索按钮）具有固定宽度。左边的项目填充了剩下的空间。

HTML：

<div class="ric-search-form">
  <button id="ricSearchButton">Search</button>
  <div class="ric-search-input-group"><span class="icon-search8"></span>
    <input style="" placeholder="Search" id="ricSearchField">
  </div>
</div>

在左侧的项目（.rich-search-input-group）中，有一个span和一个input。如何确保我的input填满剩下的.rich-search-input-group？

JSFiddle证明了这个问题。

如果您悬停并观察光标变化或键入以填充它，您可以看到输入结束的位置。

将display: flex;分配到.ric-search-input-group课程，并将<input> flex-grow: 1; .ric-search-form .ric-search-input-group { display: flex; } .ric-search-form .ric-search-input-group input { flex-grow: 1; } 。{/ p>
