Html form - ввод входов на одной строке

Я изо всех сил стараюсь сделать два входа в формате html (имя и фамилия) на одной строке рядом. Я пробовал использовать float, но, похоже, все остальные входы идут повсюду. Любые рекомендации будут очень благодарны - вот мой код:

HTML:

<form action="includes/contact.php" method="post">

    <label for="First_Name">First Name:</label>
    <input name="first_name" id="First_Name" type="text" />
    <label for="Name">Last Name:</label>
    <input name="last_name" id="Last_Name" type="text" /> 

    <label for="Email">Email:</label>
    <input name="email" id="Email" type="email" />

    <label for="Telephone">Telephone:</label>
    <input name="telephone" id="Telephone" type="tel" />

    <label for="Wedding">Wedding Date:</label>
    <input name="wedding" id="Wedding" type="date" />

    <label for="Requirements">Specific Requirements:</label>
    <textarea name="requirements" id="Requirements" maxlength="1000" cols="25" rows="6"> </textarea>

    <input type="submit" value="Submit"/>
</form> 

CSS

#contactpage form {
  overflow: hidden;
  display: block;
}

#contactpage form label {
  margin-top:12px;
  font-size: 1.15em;
  color: #333333;
  font-family: 'Roboto Condensed', Helvetica, Arial, sans-serif;
  font-weight: normal;
  line-height: 1.2;
}

#contactpage form input {
  border: 1px solid #DDDDDD;
  box-shadow: none;
  -webkit-box-shadow: none;
  -moz-box-shadow: none;
  border-radius: 0px;
  -moz-border-radius: 0px;
  -khtml-border-radius: 0px;
  -webkit-border-radius: 0px;
}

#contactpage form input[type='text'] {
  width: 22%;
  display: inline!important;
  background: #F9F9F9;
  font-family: 'Helvetica Neue', Arial, Helvetica, sans-serif;
  font-size: 1.1em;
  line-height: 1.4;
  padding: 6px;
}

#contactpage form input[type='email'],
#contactpage form input[type='tel'],
#contactpage form input[type='date'],
#contactpage form textarea {
  width: 94%;
  display: block;
  background: #F9F9F9;
  font-family: 'Helvetica Neue', Arial, Helvetica, sans-serif;
  font-size: 1.1em;
  line-height: 1.4;
  padding: 6px;
}

#contactpage form input[type='submit'] {    
  float:right;
  clear:both;
  display: block;
  background: #F9F9F9;
  color: #333333;
  font-size: 1.5em;
  font-family: 'Roboto Condensed', Helvetica, Arial, sans-serif;
  font-weight: 300;
  font-style: normal;
  text-transform: uppercase;
  text-decoration: none;
  line-height: 1.2;
  padding: 20px 20px 40px;
}

#contactpage form input[type='submit']:hover {
  color: #FFFFFF;
  background: #f1bdb5;
}

Вот JSBin Demo.
