我已经将模态实现为弹出窗口。在桌面上它正常，但在移动屏幕上，它来到一个角落而不是完全。模态代码

<div class="modal fade" id="loginmodal" role="dialog" style="display:none;position: fixed;top: 50%;left: 50%;margin-top: -15%;margin-left: -25%;margin-bottom: -50px;width:80%;height:80%;">
                    <div class="modal-dialog">

                        <!-- Modal content-->
                        <div class="modal-content" style="background-color: #2E5D2E;">


                            <div class="modal-body">
                                <h1 class="cover-heading" style="text-shadow: -1px 1px 1px #0A0401;font-weight: 900;font-size: xx-large;">Pick Ur Desired Location</h1>
                                <h5 class="cover-heading" style="text-shadow: -1px 1px 1px #0A0401;">We will get back to you promptly.</h5>

                                <form id="loginform" name="loginform" method="get" action="/query" class="form-horizontal">

                                    <div class="form-group">

                                            <label for="location" style="margin-left: 24px;">Your Location</label>

在手机屏幕上看起来像这样

如何让它成为屏幕的中心而不会破坏它在桌面等大屏幕上的位置。有人可以建议我这样做吗？

您正在应用的内联样式导致了很多问题（我删除了任何与大小位置相关的内容），当您只是希望标签本身使用col时，您将输入和标签放在col-sm-2中-sm-2，而不是那些列中包含在一起的输入和标签。

<label for="location" class="col-sm-2 control-label" style="color: #0E0E0E;white-space: nowrap;">Your Location</label>

您可以使用jQuery将模态保留在页面的中心。

参见工作示例。

$(function() {
  function reposition() {
    var modal = $(this),
      dialog = modal.find('.modal-dialog');
    modal.css('display', 'block');
    dialog.css("margin-top", Math.max(0, ($(window).height() - dialog.height()) / 2));
  }

  $('.modal').on('show.bs.modal', reposition);

  $(window).on('resize', function() {
    $('.modal:visible').each(reposition);
  });
});
