Despite #container being centered, I am struggling to center the <form>. It is important for me to have all elements inside the form aligned horizontally and despite trying various techniques, it is not working as expected.
<!-- Container Start -->
<div id="container">
<h1 class="signup-header-text">SIGN UP</h1>
<div class="clear"></div>
<form class="signup-form" action="#" method="post">
<div id="first_step">
<div class="form">
<label for="gender">You are:</label>
<br />
<select id="gender" name="gender" size="2">
<option value="1">Male</option>
<option value="2">Female</option>
</select>
<div class="clear"></div>
</div>
<div class="clear"></div>
<input class="submit" type="submit" name="submit_first" id="submit_first" value="" />
</div>
</form>
<div id="progress_bar">
<div id="progress"></div>
<div id="progress_text">0% Complete</div>
</div>
</div>
<!-- Container End -->
This snippet from my CSS:
#container {
height: 410px;
min-height: 410px;
min-width: 756px;
width: 756px;
overflow: hidden;
position: absolute;
top: 50%;
left: 50%;
margin-top: -205px; /* Half the height */
margin-left: -378px; /* Half the width */
background: #e9e5e5;
border: solid #dcdcdc 2px;
outline: solid #c4c4c4 1px;
-webkit-box-shadow: 0px 5px 15px rgba(48, 50, 50, 0.28);
-moz-box-shadow: 0px 5px 15px rgba(48, 50, 50, 0.28);
box-shadow: 0px 5px 15px rgba(48, 50, 50, 0.28);
}
