Question

我添加了图片图标的标签，我尝试在图像图标更改后单击按钮（活动按钮），book_hover.png字体颜色改变但图像图标不变，如何更换NavTab活动时刻后的图像

＆＃13;

.footer-tab .tooter-nav-tab {
  padding: 2rem;
  height: 10vh;
  width: 100%;
  margin-left: 0rem;
  background: white;
  border-top: 1px solid #c9cfd9;
  display: inline;
  text-align: center;
}

p.tab-txt {
  font-size: 0.7rem;
}

.footer-tab ul {
  list-style-type: none;
  margin: 0;
  padding: 0;
  border-top: 1px solid #c9cfd9;
  overflow: hidden;
  background-color: #ffffff;
}

.footer-tab li {
  float: left;
}

.footer-tab .nav-tabs .nav-link.active {
  color: white;

  background-color: #8bb6f3;
  border-color: #ddd #ddd #fff;
}

.footer-tab li a {
  display: block;
  color: #3f5370;
  text-align: center;
  padding: 18px 16px;
  text-decoration: none;
}

.footer-tab li a:hover {
  background-color: #8bb6f3;
  color: white;
}

.footer-tab-img :active {
  background:url'https://image.ibb.co/ffSy9F/book_hover.png')no-repeat;
  color: white;
}
/*footernavtab*/

最后我解决了我的问题，我使用了这个类footer-tab-img-01并添加了单独的彩色图像和代码克里特像这样

`span.footer-tab-img-01 { background: url('/Image/users.png') no-repeat; width: 32px; height: 32px; display: block; margin-left:1.2rem; }

.nav-link.active span.footer-tab-img-01 { background: url('/Image/users-hover.png') no-repeat; width: 32px; height: 32px; display: block; margin-left:1.2rem; }`

<div class="footer-tab">
  <ul class="nav nav-tabs" role="tablist">
    <li class="img-01 w-25"><a href="" class="nav-link"}}

                <span class="footer-tab-img-01">

                    </span>
        <p class="tab-txt">Book</p>
   </a>
    </li>
    </ul>
    </div>
