The only way I can think of is with JavaSCript:

function focusLink(isOnFocus)
{
    if (isOnFocus)
      document.getElementById('formspace').className = "<make a focus class name here>";
    else
      document.getElementById('formspace').className = "<default class name here>";
}

...  

Hope that helps!

<input onFocus="focusLink(true)" onBlur="focusLink(false)">
