A LESS mixin to tweak options in animate.css (https://github.com/daneden/animate.css). Once in place you can do: .animated-tweaker(1.2s, 0.1s, 1); //duration, delay, repeats

animated-tweaker.less

.animated-tweaker (@duration: 1.1s, @delay: 0.5s, @repeats: 1) {
          -webkit-animation-duration: @duration;
             -moz-animation-duration: @duration;
              -ms-animation-duration: @duration;
               -o-animation-duration: @duration;
                  animation-duration: @duration;

             -webkit-animation-delay: @delay;
                -moz-animation-delay: @delay;
                 -ms-animation-delay: @delay;
                  -o-animation-delay: @delay;
                     animation-delay: @delay;
