在悬停时填充元素与倾斜的背景

Question

我正在尝试创建一个CSS按钮悬停效果.但我没有设法用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;
}

<button class="button_sliding_bg">Buttontext</button>

Answer 1

您可以使用此答案中描述的技术:在悬停时从中心填充元素并倾斜伪元素,使其以倾斜方式填充按钮:

div {
  position: relative;
  display: inline-block;
  padding: 15px 70px;
  border: 5px solid #B17461;
  color: #B17461;
  font-size: 30px;
  font-family: arial;
  transition: color .5s;
  overflow:hidden;
}
div:before {
  content: '';
  position: absolute;
  top: 0; left: 0;
  width: 130%; height: 100%;
  background: #B17461;
  z-index: -1;
  transform-origin:0 0 ;
  transform:translateX(-100%) skewX(-45deg);
  transition: transform .5s;
}
div:hover {
  color: #fff;
}
div:hover:before {
  transform: translateX(0) skewX(-45deg);
}

<div>BUTTON</div>

不要忘记为浏览器支持添加供应商前缀(有关详细信息,请参阅canIuse).

Answer 2

我相信你实际上是在寻找最终状态,用背景颜色填充整个元素,而不是留下空隙.你也可以用它做linear-gradient背景图片和过渡的background-size,并background-position喜欢在下面的代码片段.

使用linear-gradientover伪元素或转换的一个缺点是浏览器支持较低但不需要额外的伪元素,因此可以留给其他用途.

.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;
  background-image: linear-gradient(135deg, #31302B 50%, transparent 51%);
  background-size: 100px 100px; /* some initial size to get the slanted appearance */
  background-position: -50px -50px; /* negative positioning to hide it initially */
  background-repeat: no-repeat;
  transition: all ease 0.8s;
}
.button_sliding_bg:hover {
  background-size: 200% 200%; /* 200% because gradient is colored only for 50% */
  background-position: 0px 0px; /* bring it fully into view */
  color: #FFF;
}
