Tạo thanh menu liên hệ cố định bên phải cho website wordpress

Đầu tiên bạn chèn code vào file functions.php và nhớ đổi lại đường dẫn ảnh (icon)

function task_right(){
    ?>
<div id="sticky-nav">
  <div class="sticky-item">
    <span class="icon-sticky"><img src="/wp-content/uploads/2021/05/edit.png"></span>
    <a href="#tongquan" class="info-expanded">Tổng quan</a>
  </div>
  <div class="sticky-item">
    <span class="icon-sticky"><img src="/wp-content/uploads/2021/05/location-2.png"></span>
    <a href="#vitri" class="info-expanded">Vị trí</a>
  </div>
  <div class="sticky-item">
    <span class="icon-sticky"><img src="/wp-content/uploads/2021/05/image.png"></span>
    <a href="#hinhanh" class="info-expanded">Hình ảnh</a>
  </div>
  <div class="sticky-item">
    <span class="icon-sticky"><img src="/wp-content/uploads/2021/05/home.png"></span>
    <a href="#maunha"class="info-expanded">Chọn mẫu nhà</a>
  </div>
  <div class="sticky-item">
    <span class="icon-sticky"><img src="/wp-content/uploads/2021/05/phone-call-3.png"></span>
    <a href="#lienhe"  class="info-expanded">Liên hệ</a>
  </div>
  <div class="sticky-item">
    <span class="icon-sticky"><img src="/wp-content/uploads/2021/05/top.png"></span>
    <a href="back-to-top" data-title="Lên đầu trang" role="button" class="info-expanded">Lên đầu trang</a>
  </div>
</div>
<?}
add_action('wp_footer','task_right');

Sau đó chèn css vào file style.css của bạn

span img { width:unset}
#sticky-nav {
    display: block;
    position: fixed;
    right: 0px;
    z-index: 997;
    top: 50%;
    transform: translateY(-50%);
}
#sticky-nav .sticky-item {
    background: #075E8E;
    overflow: hidden;
    border-bottom: 2px solid #075E8E;
    position: relative;
    display: block;
    width: 45px;
    margin: 0;
    outline-offset: -1px;
    -webkit-transition: width .6s ease-in-out;
    transition: width .6s ease-in-out;
    cursor: pointer;
    float: right;
    clear: both;
}
#sticky-nav .icon-sticky {
    vertical-align: middle;
    display: inline-block;
    text-align: center;
    width: 50px;
}
#sticky-nav .icon-sticky img {
    margin: 0 auto;
    width: 30px;
    height: 30px;
    margin: 10px;
    display: inline-block;
}
#sticky-nav .info-expanded {
    display: none;
    -webkit-transition: display .15s ease-in-out;
    transition: display .15s ease-in-out;
    color: #fff;
    font-size: 17px;
}
#sticky-nav .sticky-item:hover, #sticky-nav .sticky-item.active {
    width: 200px;
    background: #075E8E ;
    border-color: #075E8E ;
}
#sticky-nav .sticky-item:hover .info-expanded, #sticky-nav .sticky-item.active .info-expanded {
    display: block;
    position: absolute;
    width: 100%;
    height: 50px;
    top: 0px;
    line-height: 50px;
    padding-left: 50px;
    color: #fff;
    text-decoration: none;
}
