输入HTML CSS内的按钮[重复]

Question

我正在尝试使用内部按钮创建一些输入，如下所示：

我阅读了一些教程，这段代码应该可以工作，但我不知道为什么它不工作。 这是 CSS：

#content input[class="small"] {
  font-weight: 400;
  color: #909090;
  outline: none;
  margin-top: 15px;
  width: auto;
    height: 50px;
    -webkit-border-radius: 10px;
    -moz-border-radius: 10px;
    border-radius: 10px;
    border: solid 2px #e5e5e5;
  padding-left: 30px;
}

#content button[type="submit"] {
  display: inline-block;
  width: 50px;
    height: 50px;
  padding-right: 10px;
    -webkit-border-radius: 0 10px 10px 0;
    -moz-border-radius: 0 10px 10px 0;
    border-radius: 0 10px 10px 0;
    background-color: #23a298;
    border: solid 2px #e5e5e5;
}

Answer 1

在您的代码col-3>div has width 33% 中。元素没有空间适合。因此它转到下一行。那是输入框旁边的按钮，不在输入框内。

同时使用媒体查询和宽度以获得更好的输出。

<input type=text><button>Submit</button>

看看这个。按钮和输入框的对齐无需编写特殊的 CSS。

这不是输入内的按钮，而是 div 内的输入旁边的按钮，看起来像输入，您可以通过执行以下操作来实现它

$(document).ready(function(){
    $(".search-confirm").on('click', function(){
         var keyword = $("#search-field").val();
         alert("You searched - "+keyword)
    })
})

.input-outer-padding {
  position: relative;
  width: 280px;
  border: 1px solid #3c0;
  border-radius: 3px;
  overflow: hidden;
}

.input-inner-padding {
  width: auto;
  height: auto;
  padding: 5px 60px 5px 5px;
}

.input-field {
  width: 100%;
  display: block;
  /*resets for hiding the input boundaries */
  border: 0px;
  margin: 0px;
  padding: 0px;
  outline: none;
  font-family: sans-serif;
  font-size: 16px;
  color: #3c0;
}

.search-confirm {
  padding: 7px 10px;
  background-color: #3c0;
  font-family: sans-serif;
  font-size: 14px;
  font-weight: bold;
  color: white;
  cursor: pointer;
  /* here the magic begins */
  position: absolute;
  z-index: 1;
  top: 0;
  right: 0;
}

.search-confirm:hover {
  background-color: #09f;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="input-outer-padding">
  <div class="input-inner-padding">
    <input type="text" id="search-field" class="input-field" placeholder="Search" />
  </div>
  <div class="search-confirm">SEARCH</div>
</div>
