我正在尝试使用CSS创建悬停效果。这是链接:http://creativeartbd.com/demo/test.html

代码如下:

/* GENERAL BUTTON STYLING */
button,
button::after {
  -webkit-transition: all 0.3s;
    -moz-transition: all 0.3s;
  -o-transition: all 0.3s;
    transition: all 0.3s;
}

button {
  background: none;
  border: 3px solid red;
  border-radius: 5px;
  color: red;
  display: block;
  font-size: 1.6em;
  font-weight: bold;
  margin: 1em auto;
  padding: 2em 6em;
  position: relative;
  text-transform: uppercase;
}

button::before,
button::after {
  background:red;
  content: '';
  position: absolute;
  z-index: -1;
}

button:hover {
  color: black;
}


/* BUTTON 5 */
.btn-5 {
  overflow: hidden;
}

.btn-5::after {
  /*background-color: #f00;*/
  height: 100%;
  left: -35%;
  top: 0;
  transform: skew(50deg);
  transition-duration: 0.6s;
  transform-origin: top left;
  width: 0;
}

.btn-5:hover:after {
  height: 100%;
  width: 135%;
}
<button class="btn-5">Button 5</button>

现在,如果您运行它,则将鼠标悬停在按钮上时可以看到有样式。现在,我想为此按钮设置初始背景。因此, IF 我在这里设置背景:

button {
   background: orange;
}

如果我这样做,则效果没有显示。

您能告诉我原因以及如何解决吗?

z-index:0添加到元素中以创建堆栈上下文并将伪元素保留在内部。然后,您可以添加背景

/* GENERAL BUTTON STYLING */
button,
button::after {
  -webkit-transition: all 0.3s;
    -moz-transition: all 0.3s;
  -o-transition: all 0.3s;
    transition: all 0.3s;
}

button {
  background: none;
  border: 3px solid red;
  border-radius: 5px;
  color: red;
  display: block;
  font-size: 1.6em;
  font-weight: bold;
  margin: 1em auto;
  padding: 2em 6em;
  position: relative;
  z-index:0;
  background:orange;
  text-transform: uppercase;
}

button::before,
button::after {
  background:red;
  content: '';
  position: absolute;
  z-index: -1;
}

button:hover {
  color: black;
}


/* BUTTON 5 */
.btn-5 {
  overflow: hidden;
}

.btn-5::after {
  /*background-color: #f00;*/
  height: 100%;
  left: -35%;
  top: 0;
  transform: skew(50deg);
  transition-duration: 0.6s;
  transform-origin: top left;
  width: 0;
}

.btn-5:hover:after {
  height: 100%;
  width: 135%;
}
<button class="btn-5">Button 5</button>

您还可以简化代码,如下所示:

button {
  background: none;
  border: 3px solid red;
  border-radius: 5px;
  color: red;
  display: block;
  font-size: 1.6em;
  font-weight: bold;
  margin: 1em auto;
  padding: 2em 6em;
  background:
    linear-gradient(50deg,red 50%,transparent 50.5%),
    orange;
  background-size:250% 100%;
  background-position: right;
  text-transform: uppercase;
    transition: all 0.5s;
}
button:hover {
  color: black;
  background-position: left;
}
<button class="btn-5">Button 5</button>
