CSS Question

Input box not filling the entire space when the screen is small

I am practicing HTML and CSS. I have a question related to the following code-



.outer_class{
position: absolute;
width: 50%;
height: 30%;
top: 35%;
left: 25%;
background-color: red;
}
.inner_class{
position: relative;
width: 50%;
height: 50%;
top: 25%;
left: 25%;
background-color: yellow;
}
.div_input{
position: relative;
width: 70%;
height: 50%;
top: 25%;
left: 15%;
background-color: blue;
}
input[type="text"]{
box-sizing: border-box;
width: 100%;
height: 100%;

}

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Align_Textbox_To_Div_Center</title>

<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>

</head>
<body>
<div class="outer_class">
<div class="inner_class">
<div class="div_input">
<input type="text" name="username">
</div>
</div>
</div>
</body>
</html>





Now, when I am resizing the browser window to the minimum, little bit of blue div is shown. Why is that and how can I fix it?

Thanks in advance!

Answer

Add
input[type="text"]{ position:absolute; border:none; }

.outer_class{
    		position: absolute;
    		width: 50%;
    		height: 30%;
    		top: 35%;
    		left: 25%;
    		background-color: red;
    	}
    	.inner_class{
    		position: relative;
    		width: 50%;
    		height: 50%;
    		top: 25%;
    		left: 25%;
    		background-color: yellow;
    	}
    	.div_input{
    		position: relative;
    		width: 70%;
    		height: 50%;
    		top: 25%;
    		left: 15%;
            background:blue;
    	}
    	input[type="text"]{
    		box-sizing: border-box;
    		width: 100%;
    		height: 100%;
            position:absolute;
            border:none;
    	}
