[每当我从Materializecss打开一个模态时，滚动条（我的身体都有内联滚动条）每次都会隐藏。我应该怎么做，以便每当我打开一个模态时，主体的滚动条都将保留？
<body>
<div id="modal_confirm_block" class="modal modal_dialog">
<div class="modal-content white" id="modal_confirm_co_content" style="padding:0px !important;">
<div id="div_available" class="center-align" style="padding: 20px !important;"> <i class="material-icons md-12 noselect center-align amber-text darken-4" > warning</i><br>
<p style="padding:20px !important;" class="center-align"> Are you sure you want to block this guest? </p>
</div>
</div>
<div class="modal-footer">
<div class="row" style="margin: 0 !important;">
<div class="col s6"> <a href="#!" id="btn_confirm_block" class=" cyan darken-2 white-text modal-action waves-effect waves-white btn" style="width:100% !important;">Confirm</a></div>
<div class="col s6"> <a href="#!" id="btn_cancel_block" class="blue-grey darken-4 white-text modal-action modal-close waves-effect waves-white btn" style="width:100% !important; ">Cancel</a></div>
</div>
</div>
</div>
</body>
Screenshot before opening a modalScreenshot when a modal opens. Look at the scrollbar it was removed. And I don't like that because the screen always move.
对我来说，它是通过这样的方式将其放入CSS中的。
