我想在同一水平平面上保留我的div和两个选择元素。我以为这个
display: inline;
是事实和光明，但显然不是因为事情溢出到下一行。这是HTML…
<div class="profileField address">
<label for="user_address_address">Hometown</label><br>
<div class="field"><input placeholder="City" type="text" name="user[address][city]" id="user_address_city"></div>
<select name="state" id="state" class="selectMenu form-control">
<option value="">Select State</option>
<option value="AL">Alabama</option>
<option value="AK">Alaska</option>
<option value="AZ">Arizona</option>
…
<option value="WI">Wisconsin</option>
<option value="WY">Wyoming</option>
</select>
<select id="country_country_id" name="country[country_id]" style="">
<option value="0">-- Select --</option><option value="38">Canada</option>
<option value="233">United States</option><option value="0" disabled="disabled">----------------------------</option>
<option value="3">Afghanistan</option>
<option value="15">Aland Islands</option>
<option value="6">Albania</option>
<option value="62">Algeria</option>
<option value="11">American Samoa</option>
…
<option value="248">Zambia</option>
<option value="249">Zimbabwe</option>
</select>
</div>
这是我的JSFIDDLE -https://jsfiddle.net/5g8jxpa3/。知道我做错了什么或需要添加什么？
在<div>上设置display: inline-block。
.field {
border: 1px solid rgba(74,74,76,0.5) !important;
display: inline-block;
}
更新了JSFIDDLE
编辑：侧注
不要使用display: inline;，因为内部input的填充将被忽略。
虽然可以将填充物应用于内联元素的所有侧面，但左右填充只会对周围内容产生影响。
来源：内联元素和填充
div class =" field"应该显示：inline;为了显示所有相邻元素内联
div自然是块元素，这意味着它在其行上不允许其他任何内容。要解决此问题，您需要使其成为内联（或内联）元素。
所讨论的元素是.field DIV，它仅包含文本输入（为了提供城市名称，看起来像）。由于某种原因，您已将该元素的显示类型设置为table。table显示类型是block的子类型，它也可以防止其他任何内容在同一行上。
您想要的显示类型可能是 inline-block（它保留了块元素的尺寸属性，而是内联元素的线路破坏属性）。在下面的示例中，我仅编辑了CSS的第9行。
.profileField {
padding: 10px;
font-family: 'Oxygen', sans-serif;
font-weight: 300;
font-size: 20px;
}
.field {
border: 1px solid rgba(74, 74, 76, 0.5) !important;
display: inline-block;

input {
font-size: 16px;
line-height: 18px;
box-sizing: border-box;
font-family: inherit;
padding: 0.4rem 0;
text-indent: 0.8rem;
border: none;
outline: none;

</div>在我看来，您尝试将display: inline应用于所有input元素；这是不必要的，因为默认情况下输入是内联的。包装器div本身就是导致线路破裂的原因，因此您需要将规则应用于。
您可以通过在此处更改CSS类中的单个行来获得所需的结果。
.field {
display:inline-block;
}
