html - 如何将此按钮与文本框对齐？

Question

我希望按钮的左侧与文本框齐平。如果这有所作为，我正在使用 bootstrap 3。这是我的表单 html 代码。如果有必要，我也可以添加我的 CSS。谢谢。

h1 {
    	font-size:83px;
    }

    .btn-primary {
    	background: #ffffff;
    	border-color: #ffffff;
    	color: #f05324;
    }

    .btn-default, .btn-default:hover, .btn-default:focus, .btn-default:active, .btn-default.active, .open > .dropdown-toggle.btn-default {
        background: #ffffff;
    	border-color: #ffffff;
    	color: #f05324;
    }

    .panel-default {
        border: none;
    }

    input[type="text"] { 
    	color:white !important;
    } 

    input[type="email"] { 
    	color:white !important;
    } 

    .model-content {
    	color:black !important;
    }

    .text-left {
      text-align: left;
    }

    .text-right {
      text-align: right;
    }

    .text-center {
      text-align: center;
    }

    .navbar-default {
        background-color: #000000;
    }

    body {
    	background: #f05324 !important; 
    	margin-bottom: 80px;
    	color: #ffffff;
    }

    .page-header, .panel-body, .panel, .panel-default, .col-lg-9, .row {
    	background: #f05324 !important; 
    }

    .form-control{
        background-color: #f05324;
        color: #000000;
    }

    hr {
    	border-color: #ffffff;
    	background-color: #ffffff;
    	color: #ffffff;
    }

    .link {
    	color: #ffffff;
    }

    .page-header {
    	margin-top: 0;
    }

    .panel-body {
    	padding-top: 0;
    }

    .img-featured {
    	margin-top   : 15px;
    	margin-bottom: 15px;
    	margin-right : 15px;
    }

    .img-project{
    	margin-top   : 15px;
    	margin-bottom: 15px;
    }

    .show-onclick {
    	display: none;
    }

    .show-onclick1 {
    	display: none;
    }

    .block {
        position: absolute;
        top: 0;
        bottom: 0;
        left: 50%;
        margin-left: // half the width of your img
    }

如果您希望按钮的左边缘与文本框的左边缘匹配，那么您只需使用 Bootstrap 网格添加一个偏移量，如下所示:

<form class="form-horizontal" method="post" action="submit.php" enctype="multipart/form-data">
    ...
    <div class="form-group">
        <label for="itemOneImg2" class="col-sm-2 control-label">IMAGE 2:</label>
        <div class="col-sm-10">
            <input type="file" accept=".jpg, .jpeg, .png" class="form-control" name="itemOneImg2">
        </div>
    </div>

    <div class="form-group">
        <!-- Adjust col-sm-X for the buttons to adjust their positioning
             Could also add btn-block class to make the button span the column -->
        <div class="col-sm-offset-2 col-sm-9">
            <input id="additional-files" type="button" value="Additional Projects" class="btn btn-default">
        </div>
        <div class="col-sm-1">
            <input id="submit" type="button" value="Submit" class="btn btn-default">
        </div>
    </div>
</form>
