如何从css动画的剪切路径中删除奇怪的边框？

sat*_*ite 5 css css3

我在其上具有带有剪切路径（六边形）的元素pseudo（:before和:after）。

.cssload-cssload-spinner {
  position: relative;
  border: none;
}

.cssload-cssload-spinner:before,
.cssload-cssload-spinner:after {
  display: block;
  content: ' ';
  width: 88px;
  height: 88px;
  border: none;
  outline: none;
  clip-path: polygon(50% 0, 7% 26%, 7% 74%, 50% 100%, 93% 74%, 93% 26%, 83% 32%, 83% 69%, 50% 89%, 17% 69%, 17% 32%, 50% 12%, 83% 32%, 93% 26%);

用css动画制作动画的伪元素。在添加动画后，我看到了奇怪的边框。

边界！

无法使用border: none或删除它outline: none（我已经不知道了）。

我如何删除边框？

例： 

.cssload-cssload-spinner {
  position: relative;
  border: none;
}

.cssload-cssload-spinner:before,
.cssload-cssload-spinner:after {
  display: block;
  content: ' ';
  width: 88px;
  height: 88px;
  border: none;
  outline: none;
  clip-path: polygon(50% 0, 7% 26%, 7% 74%, 50% 100%, 93% 74%, 93% 26%, 83% 32%, 83% 69%, 50% 89%, 17% 69%, 17% 32%, 50% 12%, 83% 32%, 93% 26%);
