模态不适用于Android手机

Question

我上传了我的网站到互联网，但似乎模式在Android手机上无法正常工作。它适用于计算机，但移动？没那么多

<button type="button" class="btn btn-primary btn-large" data-toggle="modal" data-target="#myModal2">Sign up as an Jobseeker</button>
<button type="button" class="btn btn-primary btn-large" data-toggle="modal" data-target="#myModal">Sign up as an Employer</button>
<!-- Modal:Jobseeker -->
    <div id="myModal2" class="modal fade" role="dialog">
