添加导航栏后,我的模式上的关闭按钮在滚动时被隐藏

After adding a navigation bar the close button on my modal is hidden when scrolling

我创建了一个 JSfidle 来演示这个问题。基本上,关闭按钮应该位于模式 window 右上角的外侧,但是由于调整大小并向模式添加垂直滚动条,关闭按钮现在位于内部并在滚动时移动。有什么想法吗?

JSFiddle

/* custom modal */

.modalDialog {
    position: fixed;
    font-family: Arial, Helvetica, sans-serif;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
    background: rgba(0,0,0,0.8);
    z-index: 99999;
    opacity:0;
    -webkit-transition: opacity 400ms ease-in;
    -moz-transition: opacity 400ms ease-in;
    transition: opacity 400ms ease-in;
    pointer-events: none;
}

.modalDialog:target {
    opacity:1;
    pointer-events: auto;
}

.modalDialog > div {
    width: 750px;
    position: relative;
    margin: 10% auto;
    padding: 5px 20px 13px 20px;
    border-radius: 10px;
    background: #f3eedd;
    max-height: calc(100vh - 210px);
    overflow-y:auto;
    overflow-x:hidden;
}

.close {
    background: #606061;
    color: #FFFFFF;
    line-height: 25px;
    position: absolute;
    right: -12px;
    text-align: center;
    top: -10px;
    width: 24px;
    text-decoration: none;
    font-weight: bold;
    -webkit-border-radius: 12px;
    -moz-border-radius: 12px;
    border-radius: 12px;
    -moz-box-shadow: 1px 1px 3px #000;
    -webkit-box-shadow: 1px 1px 3px #000;
    box-shadow: 1px 1px 3px #000;
}

.close:hover { background: #00d9ff; }

  hm1 {
    font-family: 'Londrina Sketch', cursive;
    color: #c13e18;
    font-size: 50px;
    text-align: center;
    margin: 0px 30px 0px 30px;
}

hm2 {
    font-size: 20px;
    color: #c13e18;
    margin: 10px 30px 10px 30px;
}
 hm3 {
    font-size: 20px;
    margin: 30px 30px 0px 30px;
}


    pm {
    font-size: 20px;
    margin: 0px 30px 0px 30px;

}

您应该将您的文本内容移动到它自己的 div(例如 class="content"),并将滚动应用到此内容:

    .modalDialog > div {
  width: 750px;
  position: relative;
  margin: 10% auto;
  padding: 5px 0px 13px 20px;
  border-radius: 10px;
  background: #f3eedd;

  overflow: visible;
}

.content{
  max-height: calc(100vh - 210px);
  overflow-y: auto;
  padding-right: 20px;
}
