How do I vertically align a form using bootstrap?

I'm trying to make a login page using Bootstrap. So far so good, the problem is the vertical align. I want to make the login form stick to the center of the page, so I tryed reading all the other answered questions and tryed really a lot of different solutions, but to no avail. My code is the following.

.container {
  display: table;
  table-layout: fixed;
}

.form-horizontal {
  width: 500px;
  display: table-cell;
  vertical-align: middle;
  text-align: center;
}

Solution

  • It's kind of hack, but I will try to figure how I can place it exactly in the center.

    Just tried to wrap the box(.centerit) and move it's location. 

    .container {
  display: table;
  table-layout: fixed;
}

.form-horizontal {
  width: 500px;
  display: table-cell;
  vertical-align: middle;
  text-align: center;
}

#outer{
  height:800px;
  border:2px solid orange;
}

.centerit{
  border:3px solid purple;
  top:30%;
  position:relative;
}
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<div id="outer">
<div class="centerit">
<div class="container">

  <form class="form-horizontal">
    <div class="form-group">
      <label for="username" class="col-sm-2 control-label">Username</label>
      <div class="col-sm-10">
        <input type="email" class="form-control" id="username" placeholder="username" size="16">
      </div>
    </div>
    <div class="form-group">
      <label for="password" class="col-sm-2 control-label">Password</label>
      <div class="col-sm-10">
        <input type="password" class="form-control" id="password" placeholder="password" size="16">
      </div>
    </div>
    <div class="form-group">
      <div class="col-sm-offset-2 col-sm-10">
        <button type="submit" class="btn btn-primary btn-lg btn-block" id="signin_button" value="Sign In">Sign in</button>
      </div>
    </div>
  </form>

</div>
