我正在尝试使用名为scrollToFixed的插件来修复滚动标题，就像iOS联系人列表一样。我无法看到如何使标题（.learning-objective-header）固定并相对于容器。

$('.learning-objective-header').scrollToFixed();
答案 0 :(得分：1)
我不认为该插件提供了一种处理相对固定定位的方法。但是，它确实提供了根据屏幕顶部和底部的位置绝对定位固定元素的选项。因此，如果你知道固定元素上方区域的高度，你可以简单地使用marginTop选项来设置位置，如下所示：
$(document).ready(function() {
$('.learning-objective-header').scrollToFixed({
marginTop: 137
});
});
