为什么我的主页导航显示与子页面不同？

Question

主页与子页面上字母之间的字距调整是关闭的。我不知道为什么他们都在 html 和 css 的导航链接中使用相同的代码。我在下面附上了一些 css 和 html，我不确定只有主页发生了什么，就像我说的所有子页面在这里都有相同的代码。

    <header>
         <div class="container"> 
        <nav class="navbar">
          <div class="logo"><img src="logo/logo_white.svg" alt="vic logo"/>
                  </div>
            <ul class="nav_links">
                <li class="active"> 
                    <a href="index.html" class="nav_link">home</a>
                    <li>
                     <a href="stills.html" class="nav_link">stills</a>
                    </li>
                    <li>
                       <a href="designs.html" class="nav_link">designs</a>
                    </li>
                </ul>
                </nav>
                 </header>

    /* hover link*/
    li, a:hover {

        text-decoration: underline;
        font-weight: 600;

    /* selected link */
    li, a:active {
