Fix: Section Navigation not working

Hi!

I cam across a bug:

on safari the section navigation shows no bullet circle, only the point of the active site.

Chrome desktop does.

I investigated this and found that safari only accepts keyframes, if all 100% are used.

therefore it ignores the c-bully__bullet–pop, but c-bully__bullet–current is shown (you see the dot where you are), but not the circle for the possible navigations.

This is, as the stylesheet does not provide information for all 100% of the keyframe.

Thefore in the style.css @-webkit-keyframes bully-pop and @keyframes bully-pop need to have 0% information added as the just provide 50% and 100%. The 0% is never used, but otherwise safari ignores it.
So the change needed is in stylesheet.css

@-webkit-keyframes bully-pop {
  50% {
    -webkit-transform: scale(0.7);
            transform: scale(0.7);
  }
  100% {
    -webkit-transform: scale(1);
            transform: scale(1);
  }
}
@keyframes bully-pop {

  50% {
    -webkit-transform: scale(0.7);
            transform: scale(0.7);
  }
  100% {
    -webkit-transform: scale(1);
            transform: scale(1);
  }
}

to

@-webkit-keyframes bully-pop {
	 0% {
    -webkit-transform: scale(0);
            transform: scale(0);
  }
  50% {
    -webkit-transform: scale(0.7);
            transform: scale(0.7);
  }
  100% {
    -webkit-transform: scale(1);
            transform: scale(1);
  }
}
@keyframes bully-pop {
	0% {
    -webkit-transform: scale(0);
            transform: scale(0);
  }
  50% {
    -webkit-transform: scale(0.7);
            transform: scale(0.7);
  }
  100% {
    -webkit-transform: scale(1);
            transform: scale(1);
  }
}
