显示图标按钮-引导程序3 [英] Reveal Icon Button - Bootstrap 3

问题描述

如何在TB3中将鼠标悬停在按钮内部创建显示图标.我试图使用CSS过渡和position属性来模仿这种行为.但是我本质上需要的是为图标和按钮设置单独的背景色.这就是我现在正在做的事情.

How to create a reveal icon inside button on hover in TB3. I tried to mimic this behavior using CSS transitions and position property. But I essentially need is to have a separate background color for icon and button. Here is what I am doing right now.

HTML标记

<button class="btn btn-dark icon-revealed">
    <span class="glyphicon glyphicon-cloud-download"></span>
    Download
</button>

CSS代码

.btn.icon-revealed > span {
    left: -30px;
    width: 0;
    -webkit-transition: all .5s ease-in-out;
    -moz-transition: all .5s ease-in-out;
    -o-transition: all .5s ease-in-out;
    -ms-transition: all .5s ease-in-out;
}
.btn.icon-revealed:hover > span {
    width: 20%;
    -webkit-transform: translate(2em,0);
    -moz-transform: translate(2em,0);
    -o-transform: translate(2em,0);
    -ms-transform: translate(2em,0);
}

我想实现的目标

请注意，在悬停状态下，图标和按钮的背景色已更改.我做不到.如何在TB3中实现这一目标?

Notice the background color of icon and button changed on hover state. I could not able to do that. How can I achieve this in TB3?

推荐答案

这是平滑过渡的另一种方法.

Here's an alternative way that smooths out the transition.

.btn-dark {
  border: none;
  font-family: inherit;
  font-size: inherit;
  color: #fff;
  background: none;
  padding: 15px 30px;
  display: inline-block;
  text-transform: uppercase;
  letter-spacing: 1px;
  font-weight: 500;
  outline: none;
  position: relative;
  -webkit-transition: all 0.3s;
  -moz-transition: all 0.3s;
  transition: all 0.3s;
}
.btn-dark:after {
  content: '';
  position: absolute;
  z-index: -1;
  -webkit-transition: all 0.3s;
  -moz-transition: all 0.3s;
  transition: all 0.3s;
}
.btn-icon {
  background: #4E7878;
  color: #fff;
  line-height: 20px;
  font-size: 14px;
  overflow: hidden;
  -webkit-backface-visibility: hidden;
  -moz-backface-visibility: hidden;
  backface-visibility: hidden;
}
.btn-icon span {
  display: inline-block;
  width: 100%;
  height: 100%;
  -webkit-transition: all 0.3s;
  -webkit-backface-visibility: hidden;
  -moz-transition: all 0.3s;
  -moz-backface-visibility: hidden;
  transition: all 0.3s;
  backface-visibility: hidden;
}
.btn-icon:before {
  background: #4A6B6B;
  position: absolute;
  height: 100%;
  width: 30%;
  line-height: 2.5;
  font-size: 150%;
  -webkit-transition: all 0.3s;
  -moz-transition: all 0.3s;
  transition: all 0.3s;
}
.btn-download:hover span {
  -webkit-transform: translateX(25%);
  -moz-transform: translateX(25%);
  -ms-transform: translateX(25%);
  transform: translateX(25%);
  color: #fff;
}
.btn-download:before {
  left: -100%;
  top: 0;
}
.btn-download:hover:before {
  left: 0%;
}
.icon-reveal:before {
  content: "\e197";
  font-family: 'Glyphicons Halflings';
