我有这个页面，如果你滚动到中间，你会看到一个Select Shipping Method下拉菜单，如果你点击它。它将推动Review Terms & Conditions链接down...here是我的代码

<div class="shipping-box lf">
<div class="ship-box1 lf">
    <div class="sel-ship lf">
        <div class="ss lf">
            <span class="lf">Select Shipping Method</span>

    $(this).parents('.sel-ship').find('.dropdown').slideToggle();

});

关于如何确保术语链接保持在适当位置的想法

Answer 1

这会帮你解决这个问题：

.sel-ship { position: relative; }
.dropdown { position: absolute; top: 25px; }

Answer 2

尝试添加以下内容：

.sel-ship{
    position:absolute;
}
.terms{
    margin-top:30px;
}

Answer 3

为.sel-ship类position:absolute;设置，为.terms类设置margin-top:35px;设置
