Hi CSS guys:

let me assume that parent DOM has three child DOM which are a, b, c

<div id="parent" style="height:300px;">
       <div id="child a" style="height:30px;"></div>
       <div id="child b"style="height:100%;"></div>
        <div id="child c" style="height:60px;"></div>
</div>

if we declare style like above, the div b's height will be 300px the same with div parent, and the total height of a+b+c will e 390px, which will exceed parent dom's height 300px.

I want to propose that, can we let height not equal to parent DOM's height, but equal to parent DOM's remaining height, which in this example will be "300-30-60" px.

comments and suggestions are welcome
