css - 固定宽度元素左侧的动态全宽容器内的全宽输入

Question

有点难以在标题中解释......但基本上我需要右侧的元素(搜索按钮)具有固定宽度。左侧的元素填充其余空间。

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>

在左侧的元素 (.rich-search-input-group) 中有一个 span 和一个 input。如何确保我的 input 填满 .rich-search-input-group 的剩余部分？

JSFiddle演示问题。

如果您将鼠标悬停并观察光标的变化，或者如果您键入以填写它，您可以看到输入结束的位置。

分配display: flex;给你的.ric-search-input-group上课，然后给你 <input>一个flex-grow: 1; .

CSS

.ric-search-form .ric-search-input-group {
    display: flex;
}

.ric-search-form .ric-search-input-group input {
    flex-grow: 1;
}

body {
  background-color:white;
}
.ric-search-form {
    font-family: "Knowledge Regular";
    overflow: hidden;
    margin-bottom: 23px;
}
.ric-search-form button {
    float: right;
    width: 120px;
    height: 32px;
    background-color: #ff8000;
    color: #fff;
    border-radius: 2px;
    border: none;
    font-size: 14px;
    font-weight: bold;
    margin-left: 15px;
}
.ric-search-form .ric-search-input-group {
    width: auto;
    overflow: hidden;
    border-bottom: 1px solid #c8c8c8;
    margin-right: 15px;
    display: flex;
}
.ric-search-form .ric-search-input-group span {
    font-size: 26px;
    color: #c8c8c8;
}
[class^="icon-"], [class*=" icon-"] {
    font-family: 'icomoon';
    speak: none;
    font-style: normal;
    font-weight: normal;
    font-variant: normal;
    text-transform: none;
    line-height: 1;
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
}
.ric-search-form .ric-search-input-group input {
    outline: none;
    border: none;
    font-size: 28px;
    padding-left: 15px;
    color: #9b9b9b;
    flex-grow: 1;
}

<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>
