我有下面的菜單，當前從左側滑入并從左側覆蓋屏幕的 30%。如何使這張幻燈片從右側進入并固定在屏幕的右側？我曾嘗試將 CSS 行“left:-150%”更改為“right:-150px”，但這只會導致菜單在您打開菜單時淡入淡出...我還希望在菜單打開時禁用頁面滾動...謝謝！jQuery(document).ready(function($){    $('.btn-open-menu').click(function () {        $('header').addClass('open');    });    $('.link-menu').click(function () {        $('header').removeClass('open');    });    $('.btn-close-menu').click(function () {        $('header').removeClass('open');    });});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script><header>  <a class="btn-open-menu">    <span class="hamburguer"><img src="/wp-content/uploads/2020/08/hamburger.png"</span>  </a>    <div class="header-content">    <a class="btn-close-menu"></a>    <nav>     <div class="Menu">  <ul class="Menu-list" data-offset="10">    <li class="Menu-list-item" data-offset="20" onclick="location.href='/home';">      Home      <span class="Mask"><span>Home</span></span>      <span class="Mask"><span>Home</span></span>    </li>    <li class="Menu-list-item" data-offset="16" onclick="location.href='/about';">      About      <span class="Mask"><span>About</span></span>      <span class="Mask"><span>About</span></span>    </li>    <li class="Menu-list-item" data-offset="12" onclick="location.href='/contact';">      Contact      <span class="Mask"><span>Contact</span></span>      <span class="Mask"><span>Contact</span></span>    </li>  </ul></div>    </nav>        <div class="social">                  <a href="https://www.instagram.com/jvaleskasilva/" target="_blank">        <i class="fab fa-instagram"></i>      </a>      <a href="https://www.facebook.com/jvaleskasilva" target="_blank">        <i class="fab fa-facebook-f"></i></i>      </a>    </div>  </div></header>
