How to put inputs into other input - css

Question

I have two inputs, first is type="text" and second one is type="submit". I'm trying to show the button one inside first input.
.inputs {
width: 245px;
padding: 15px 25px;
font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif;
font-weight: 400;
font-size: 14px;
color: #9D9E9E;
text-shadow: 1px 1px 0 rgba(256, 256, 256, 1.0);
background: #FFF;
border: 1px solid #FFF;
border-radius: 5px;
box-shadow: inset 0 1px 3px rgba(0, 0, 0, 0.50);
-moz-box-shadow: inset 0 1px 3px rgba(0, 0, 0, 0.50);
-webkit-box-shadow: inset 0 1px 3px rgba(0, 0, 0, 0.50);
}
<form>
<input type="email" class="inputs" placeholder="Enter your e-mail" name="email" required="required" />
<input type="submit" value="subscribe" id="subbutton" />
</form>
This is what I want to create

Answer 1

You could achieve this by positioning the icon and the button absolutely and giving them appropriate styles.
form {
display: inline-block;
padding: 0;
margin: 0;
position: relative;
}
.inputs {
width: 245px;
padding: 15px 82px 15px 50px;
font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif;
font-weight: 400;
font-size: 14px;
color: #9D9E9E;
text-shadow: 1px 1px 0 rgba(256, 256, 256, 1.0);
background: #FFF;
border: 1px solid #FFF;
border-radius: 5px;
box-shadow: inset 0 1px 3px rgba(0, 0, 0, 0.50);
}
#subbutton {
position: absolute;
background:#EEE;
border:none;
font-size:1em;
color: #3C3B39;
right: 0;
bottom: 2px;
width: auto;
font-size: 13px;
height: calc(100% - 4px);
box-sizing: border-box;
border-top-right-radius: 5px;
border-bottom-right-radius: 5px;
cursor: pointer;
box-shadow: inset 0 1px 3px rgba(0, 0, 0, 0.50);
}
#subbutton:hover {
background: #C4C4C4;
}
input:focus {
outline: 0;
}
#subbutton::-moz-focus-inner {
border: 0;
}
#envelope {
position: absolute;
width: 50px;
height: 100%;
line-height: 50px;
text-align: center;
font-size: 40px;
background: url(http://3.bp.blogspot.com/-LjFGCzX54lw/VMP2MYfNh2I/AAAAAAAAAF4/5lfFXmCwIjk/s1600/Screenshot_1.png) no-repeat;
background-position: 5px 10px;
}
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css">
<form>
<div id="envelope"></div>
<input type="email" class="inputs" placeholder="Enter your e-mail" name="email" required="required" />
<input type="submit" value="Subscribe" id="subbutton" />
</form>
