No space between two input fields [duplicate]

I want no space between the input elements. I tried to remove the margin from the button but nothing changed.

.form{
  float: left;
  margin-top:12px;
  margin-left: 30px;
}
.input-search{
  width:300px;
}
.input-search-button{
  margin:0px;
  padding: 0px;
  width: 15px;
  height: 21px;
}

    

<form class="form" action="" method="get" accept-charset="utf-8">
  <input class="input-search" type="text" name="">
  <input class="input-search-button" type="button" name="">
</form>
