asp网络css中的响应按钮

Question

作为标题状态。我有这个弹出窗口，我需要做出响应。现在，当我调整窗口大小时，出于某种原因，这些按钮会脱离窗口。我已经使用％而不是像素，仍然没有。任何人有建议？

CSS：

.modal { 
    display: none; 
    position: fixed; 
    z-index: 1; 
    padding-top: 100px; 
    left: 0; 
    top: 0; 
    width: 100%; 
    height: 100%; 
    overflow: auto; 
    font-size: 13px; 
    background-color: rgb(0,0,0); 
    background-color: rgba(0,0,0,0.4); 
} 

.modal-content { 
    background-color: #fefefe; 
    margin: auto; 
    margin-top: 200px; 
    padding: 20px; 
    border: 2px solid cornflowerblue; 
    width: 21%; 
    height: 10.5%; 
    min-width: 400px; 
    min-height: 15%; 
} 

.modalHdr { 
    margin-left: -1px; 
    font-size: 20px; 
} 

.popupConfirm { 
    border: 1px #aaa; 
    padding: 10px 82px; 
    text-align: center; 
    text-decoration: none; 
    display: inline-block; 
    font-size: 13px; 
    margin: 20% 2px; 
    cursor: pointer; 
    background: lightgrey; 
    color: black; 
} 

ASPX：

<div id="myModal" class="modal"> 
       <div class="modal-content"> 
        <h3 class="modalHdr"> 
         <asp:Label runat="server" Text="TRNSLTDelete Contact" /> 
        </h3> 
        <asp:LinkButton ToolTip="TRNSLTNo" ID="ButtonNo" runat="server" Text="TRNSLTNo" CssClass="popupConfirm" /> 
        <asp:LinkButton OnClick="ButtonYes_OnClick" ToolTip="TRNSLTYes" ID="ButtonYes" runat="server" Text="TRNSLTYes" CssClass="popupConfirm" /> 
       </div> 
      </div>
