我正在使用bootstrap来设计网页。我有两个主要问题。首先，无法真正弄清楚如何在form中对齐字段。其次，调整form tag中的字段（宽度高度等）。我是否必须为每个字段使用css？我试过这样做，但随后对齐搞砸了。这是我的代码。
<div class="container">
<form class="form-inline">
<div class="form-group">
<label class="form-control">In Out Specifier</label>
<select class="form-control" id="processInOutSpecifier" name="inOutSpecifier" >
<option></option>
</select>
</div>
<div class="form-group">
<label class="form-control" id="callDateLabel">Call Date</label>
<select class="form-control" id="callDate" name="callDate" >
<option></option>
</select>
</div>
<div class="form-group">
<label class="form-control" id="processCallDateFormatLabel" >Call Date Format</label>
<select class="form-control" id="callDate" name="callDateForamt">
<option>yyyy-MM-dd</option>
<option> yyyy/MM/dd</option>
<option> MM-dd-yyyy</option>
<option> MM/dd/yyyy</option>
<option> dd-MM-yyyy</option>
<option> dd/MM/yyyy</option>
<option>dd/MM/yy</option>
<option> MM/dd/yy</option>
<option> yyMMdd</option>
<option> MMddyy</option>
<option> dd.MM.yy</option>
<option> MM.dd.yy</option>
<option>MM.dd.yy</option>
<option>dd/MM</option>
<option>dd-MM</option>
</select>
</div>
<div class="form-group">
<label class="form-control">Call Time</label>
<select class ="form-control" id="callTime" name="callTime" >
<option></option>
</select>
</div>
<br><br>
<div class="form-group">

<option> HH:MM/12 HOUR</option>
<option> HH:MM/24 HOUR</option>
<option> HH:MM/AMPM</option>
<option>HHMM/24 HOUR</option>
</select>
</div>
<div class="form-group">
<label class="form-control" >Trunk </label>
<input class="form-control" type="text" id="processTrunk" placeholder="Trunk">

<div class="form-group">
<label class="form-control" >Duration </label>
<input class="form-control" type="text" id="processDuration" placeholder="Duration">
