Stretching input text to fill the division it is contained in

I have a HTML div which contains a label and input text. I want the label to take minimum space and give the remaining space to the text input. In other words, once the label has occupied its space, I want the text input to stretch horizontally to the end of the div it is contained in开发者_如何学Python. Here is the sample code that I am using.

<div>
    <label >Some Label</label>  <!--Should take minimum space -->
    <input type="text"/>        <!--Should stretch horizontally to fill up entire div --> 
</div>
