How can I stop this from happening?
This is the code for my contact us form. I'm using bootstrap. When I expand the text area it crosses the division. Any alternative I could try inside the textarea by adding inline CSS?
<div id="content">
<div class="container">
<div class="col-md-12">
<ul class="breadcrumb">
<li><a href="index.php">Home</a></li>
<li><a href="index.php">Contact Us</a></li>
</ul>
<!--breadcrumb ends--->
</div>
<!---col-md-12 ends-->
<div class="col-md-3">
<?php include("sidebar.php"); ?>
</div>
<!--col-md-3 ends--->
<div class="col-md-9">
<div class="box">
<div class="box-header">
