Minor tweak to responsive css

Hi guys,

Any chance you could modify css from line line 79 of the columns.css file from this

@media screen and (max-width: 767px) {
  .rwmb-column {
    width: 100%;
  }
  .rwmb-column .rwmb-input input {
    width: 99%;
  }
  .rwmb-field .select2-container {
    width: 99%;
  }
}

to this:

@media screen and (max-width: 767px) {
  .rwmb-column {
    width: 100%;
  }
  .rwmb-column .rwmb-input input:not([type="checkbox"]):not([type="radio"]) {
    width: 99%;
  }
  .rwmb-field .select2-container {
    width: 99%;
  }
}

This would prevent checkboxes and radio buttons from trying to take on 99% of the available width when viewed on a small device such as a phone.

Cheers,

Will
