css3气泡，1px的三 Angular 形

Question

我正在使用 CSS3 并制作一些气泡。

我有一个问题，我需要一个边框为 1px 的三 Angular 形，但是我的代码有一个粗三 Angular 形..

这是我的 fiddle :FIDDLE

和代码:

<p class="triangle-border right">hi hi</p>

.triangle-border {
  position:relative;
  padding:15px;
  color:#333;
  background:#fff;
  margin-left:100px;
  margin-right:100px;
}

.triangle-border.right {
  margin-right:50px;
  border:3px solid #EEEEEF;
}

.triangle-border:before {
  content:"";
  position:absolute;
  bottom:-20px; /* value = - border-top-width - border-bottom-width */
  left:40px; /* controls horizontal position */
  border-width:20px 20px 0;
  border-style:solid;
  border-color:#EEEEEF transparent;
  /* reduce the damage in FF3.0 */
  display:block;
  width:0;
}

/* creates the smaller  triangle */
.triangle-border:after {
  content:"";
  position:absolute;
  bottom:-13px; /* value = - border-top-width - border-bottom-width */
  left:47px; /* value = (:before left) + (:before border-left) - (:after border-left) */
  border-width:13px 13px 0;
  border-style:solid;
  border-color:#fff transparent;
  /* reduce the damage in FF3.0 */
  display:block;
  width:0;
}

/* creates the larger triangle */
.triangle-border.right:before {
  top:10px; /* controls vertical position */
  bottom:auto;
  left:auto;
  right:-30px; /* value = - border-left-width - border-right-width */
  border-width:15px 0 15px 30px;
  border-color:transparent #EEEEEF;
}

/* creates the smaller  triangle */
.triangle-border.right:after {
  top:16px; /* value = (:before top) + (:before border-top) - (:after border-top) */
  bottom:auto;
  left:auto;
  right:-21px; /* value = - border-left-width - border-right-width */
  border-width:9px 0 9px 21px;
  border-color:transparent #fff;
}

你看到右边的三 Angular 形了吗？我需要一个只有 1 像素边框的三 Angular 形。谢谢!

How's this?

/* creates the larger triangle */
.triangle-border.right:before {
  top:14px; /* controls vertical position */
  bottom:auto;
  left:auto;
  right:-22px; /* value = - border-left-width - border-right-width */
  border-width:11px 0 11px 22px;
  border-color:transparent #EEEEEF;
}

我刚玩过 border-width 和 top/left 定位
