Bootstrap всплывающее окно не на кнопке

Question

У меня странная проблема, когда всплывающее окно отключается от кнопки. Я воссоздал проблему в Fiddle , но не смог определить источник проблемы. Я не знаю, какая часть CSS вызывает проблемы. Вот код, который создает кнопку, но я не связал CSS, потому что он довольно длинный и по большей части не связан с всплывающими окнами, но его можно увидеть в Fiddle.

<script src="~/lib/bootstrap/dist/js/bootstrap.bundle.min.js"></script>
<div class="row">    
    <div class="container offset-3 col-4 mt-5" style="height:200px;">
        <a tabindex="0" class="btn btn-primary" data-placement="left" role="button" data-html="true" data-toggle="popover" title="Incorrect Info"
           data-content="And here's some amazing content. It's very engaging. Right?">
            Incorrect Info?
        </a>
    </div>
</div>

Смещение всплывающего окна

Answer 1

Это из-за маржи, которую вы установили для тега html.

  $(document).ready(function () { //enables popover
        $('[data-toggle="popover"]').popover();
    });
