在固定位置制作弹出框

Question

我使用 bootstrap v4.3.1，现在弹出框工作正常，但是当用户滚动弹出框位置下降时，我想让它固定在顶部。

我尝试覆盖样式但仍然无法正常工作！

  $('[data-toggle="popover"]').popover({
        placement: 'top',
        html: true,
        title: 'test <a href="#" class="close" data-dismiss="alert">&times;</a>',
        content: '<div class="media"><a href="#" class="pull-left"></a><div class="media-body"><p>test.</p></div></div>'
    });
    $(document).on("click", ".popover .close", function () {
        $(this).parents(".popover").popover('hide');
    });

   <a data-toggle="popover">
        <i class="fas fa-info-circle"></i></a>

Answer 1

由于position:absolute被添加到 popover inline ... 我们必须使用 !important 来覆盖它；

下面的工作片段：

 $('[data-toggle="popover"]').popover({ placement: 'top', html: true, title: 'Test title <a href="#" class="close" data-dismiss="alert">&times;</a>', content: '<div class="media"><a href="#" class="pull-left"></a><div class="media-body"><p>test description</p></div></div>' }); $(document).on("click", ".popover .close", function() { $(this).parents(".popover").popover('hide'); });

 .popover.show { position: fixed !important; }

I have a simple two column layout. The right column has a table of contents, the left column has a lot of markup with paragraphs, lists, images, and so on. I would like the content of the left column to use the whole width (of both columns) where the table of contents (which takes less vertical space) ends. Like wrapping around an image except this is wrapping around a with lots of stuff inside. Is this possible (whether or not you think its a good idea?)</div> <h1>Continued text (6 col at the start and then all width) </h1> <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit... What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? Where can I get some? There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarrassing hidden in the middle of text. All the Lorem Ipsum generators on the Internet tend to repeat predefined chunks as necessary, making this the first true generator on the Internet. It uses a dictionary of over 200 Latin words, combined with a handful of model sentence structures, to generate Lorem Ipsum which looks reasonable. The generated Lorem Ipsum is therefore always free from repetition, injected humour, or non-characteristic words etc.Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris...</p> <h3>continuing...</h3> <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit...Where does it come from? Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32. The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like). Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris...</p>
