As Felipe Asuncion reported, there is no method that will modify a property in parentElement from childElement yet, this will only be present in CSS4 ... you can do this with both jQuery and pure javascript . Here's an example I put together that does exactly what you need in pure javascript:

var inputSearch = document.querySelector('header input[type=search]');

inputSearch.addEventListener('focus', function() {
  this.parentElement.parentElement.parentElement.classList.toggle('searchfocus');
}, false);

inputSearch.addEventListener('blur', function() {
  this.parentElement.parentElement.parentElement.classList.toggle('searchfocus');
}, false);
