在悬停时填充元素与倾斜的背景

Question

我正在尝试创建 CSS按钮悬停效果。但我没有设法以倾斜的形状填充元素。

如何计划悬停效果：

屏幕截图1：它实际上看起来如何。

屏幕截图2：我希望悬停效果看起来像是倾斜的一面。

.button_sliding_bg {
  color: #31302B;
  background: #FFF;
  padding: 12px 17px;
  margin: 25px;
  font-family: 'OpenSansBold', sans-serif;
  border: 3px solid #31302B;
  font-size: 14px;
  font-weight: bold;
  letter-spacing: 1px;
  text-transform: uppercase;
  border-radius: 2px;
  display: inline-block;
  text-align: center;
  cursor: pointer;
  box-shadow: inset 0 0 0 0 #31302B;
  -webkit-transition: all ease 0.8s;
  -moz-transition: all ease 0.8s;
  transition: all ease 0.8s;
}
.button_sliding_bg:hover {
  box-shadow: inset 200px 0 0 0 #31302B;
  color: #FFF;
}
