如何修复Sidenav在Chrome中显示而不在Safari中显示-（Angular 7 / Bootstrap项目）

Question

我的导航栏出现并在Chrome中完美运行，但在Safari中却无法正常运行。试图找到使它崩溃的代码。这是一些显示两个侧面导航的照片。 Chrome是适用的浏览器，而Safari是空白的浏览器。

我已经尝试在Safari和Chrome上使用开发工具，以检查是否删除了CSS样式属性，但它们似乎都存在。

<div id="mySidenav" class="sidenav custom-underline">
  <a href="javascript:void(0)" class="closebtn" onclick="closeNav()">&times;</a>
  <div class="nav-items">
      <a href="#/home">Home</a>
      <a href="#/videos">Videos</a>
      <a href="#/art">Art</a>
      <a href="#/graphic-design">Graphic Design</a>
      <a href="#/contact">Contact</a>

      <a href="http://instagram.com/*****" class="fa fa-instagram"></a>
  </div>
</div>

和CSS

    .nav-items a:hover{
    background-color: rgb(214, 0, 0);
}

i{
    color: white;
}


/* The side navigation menu */
.sidenav {
    height: 100%; /* 100% Full-height */
    width: 0; /* 0 width - change this with JavaScript */
    position: fixed; /* Stay in place */
    z-index: 1; /* Stay on top */
    top: 0; /* Stay at the top */
    left: 0;
    background-color: rgb(0, 0, 0); /* Black*/
    overflow-x: hidden; /* Disable horizontal scroll */
    padding-top: 60px; /* Place content 60px from the top */
    transition: 0.5s; /* 0.5 second transition effect to slide in the sidenav */
}

/* The navigation menu links */
.sidenav a {
    padding: 8px 8px 8px 32px;
    text-decoration: none;
    font-size: 25px;
    color: #818181;
    display: block;
    transition: 0.3s;
}

/* When you mouse over the navigation links, change their color */
.sidenav a:hover {
    color: #f1f1f1;
}

/* Position and style the close button (top right corner) */
.sidenav .closebtn {
    position: absolute;
    top: 0;
    right: 25px;
    font-size: 36px;
    margin-left: 50px;
}

.nav-logo{
    height: 200px;
    display: block;
    margin: auto;
    margin-bottom: 50px;

}

.closebtn{
    margin-top: 8px;

}

#video-icon{
    float:left;
    margin-right:10px;
    position: relative;
    top:9px;
}

/* Style page content - use this if you want to push the page content to the right when you open the side navigation */
#main {
    transition: margin-left .5s;
    padding: 20px;
    color: black;
    background-color: rgb(0, 0, 0);
    height: 200px;
}


/* On smaller screens, where height is less than 450px, change the style of the sidenav (less padding and a smaller font size) */
@media screen and (max-height: 450px) {
    .sidenav {padding-top: 15px;}
    .sidenav a {font-size: 18px;}
}
