html - 文本区域不可编辑/无法在文本区域中键入文本

Question

我是网络开发的新手。

我有一个用 nodejs-html-css-js 编写的网络应用程序。

我有一个文本区域，但我无法输入或插入任何内容。它嵌入到幻灯片弹出窗口中。这是代码。

.cd-panel-container h1{
  color: #ffffff;
  font-size: 15px;
  font-weight: 200;
  text-align: center;
  position: absolute;
  top: 25px;
  right: 155px;
  /*display: inline-block;
  overflow: hidden;
  text-indent: 100%;
  white-space: nowrap;*/

}
.cd-panel-container h1:before {
  content:' ';
  width: 120px;
  display:block;
  border:1.5px solid #00DED4;
  border-radius:2px;
  -webkit-border-radius:4px;
  -moz-border-radius:4px;
  box-shadow:inset 0 1px 1px rgba(0, 0, 0, .05);
  -webkit-box-shadow:inset 0 1px 1px rgba(0, 0, 0, .05);
  -moz-box-shadow:inset 0 1px 1px rgba(0, 0, 0, .05);
}

.post-textarea textarea {

在上面的代码片段中，我可以获取文本区域，但无法对其进行编辑。

但是，如果我插入一个新的 CSS 片段，则什么也看不到。这是该片段。

*::after, *::before {
  content: '';
}

a {
  color: #89ba2c;
  text-decoration: none;
}
.cd-panel {
  position: fixed;
  top: 0;
  left: 0;
  height: 100%;
  width: 100%;
  visibility: hidden;
  -webkit-transition: visibility 0s 0.6s;
  -moz-transition: visibility 0s 0.6s;
  transition: visibility 0s 0.6s;
}

.cd-panel::after {
  /* overlay layer */
  /*position: absolute;*/
  /*top: 0;*/
  /*left: 0;*/
  /*width: 100%;*/
  /*height: 100%;*/
  /*background: transparent;*/
  /*cursor: pointer;*/
  /*-webkit-transition: background 0.3s 0.3s;*/
  /*-moz-transition: background 0.3s 0.3s;*/
  /*transition: background 0.3s 0.3s;*/
}

.cd-panel.is-visible {
  visibility: visible;
  -webkit-transition: visibility 0s 0s;
  -moz-transition: visibility 0s 0s;
  transition: visibility 0s 0s;
}

.cd-panel.is-visible::after {
  background: rgba(0, 0, 0, 0.6);
  /*background: #00bdff;*/
  -webkit-transition: background 0.3s 0s;
  -moz-transition: background 0.3s 0s;
  transition: background 0.3s 0s;
}

.cd-panel.is-visible .cd-panel-close::before {
  -webkit-animation: cd-close-1 0.6s 0.3s;
  -moz-animation: cd-close-1 0.6s 0.3s;
  animation: cd-close-1 0.6s 0.3s;
}

.cd-panel.is-visible .cd-panel-close::after {
  -webkit-animation: cd-close-2 0.6s 0.3s;
  -moz-animation: cd-close-2 0.6s 0.3s;
  animation: cd-close-2 0.6s 0.3s;
}


@-webkit-keyframes cd-close-1 {
  0%, 50% {
    -webkit-transform: rotate(0);
  }
  100% {
    -webkit-transform: rotate(45deg);
  }
}

@-moz-keyframes cd-close-1 {
  0%, 50% {
    -moz-transform: rotate(0);
  }
  100% {
    -moz-transform: rotate(45deg);
  }
}

@keyframes cd-close-1 {
  0%, 50% {
    -webkit-transform: rotate(0);
    -moz-transform: rotate(0);
    -ms-transform: rotate(0);
    -o-transform: rotate(0);
    transform: rotate(0);
  }
  100% {
    -webkit-transform: rotate(45deg);
    -moz-transform: rotate(45deg);
    -ms-transform: rotate(45deg);
    -o-transform: rotate(45deg);
    transform: rotate(45deg);
  }
}

@-webkit-keyframes cd-close-2 {
  0%, 50% {
    -webkit-transform: rotate(0);
  }
  100% {
    -webkit-transform: rotate(-45deg);
  }
}

@-moz-keyframes cd-close-2 {
  0%, 50% {
    -moz-transform: rotate(0);
  }
  100% {
    -moz-transform: rotate(-45deg);
  }
}

@keyframes cd-close-2 {
  0%, 50% {
    -webkit-transform: rotate(0);
    -moz-transform: rotate(0);
    -ms-transform: rotate(0);
    -o-transform: rotate(0);
    transform: rotate(0);
  }
  100% {
    -webkit-transform: rotate(-45deg);
    -moz-transform: rotate(-45deg);
    -ms-transform: rotate(-45deg);
    -o-transform: rotate(-45deg);
    transform: rotate(-45deg);
  }
}

问题是，我将需要两个 CSS 片段来实现我的目标。逻辑:我点击一个按钮，一个幻灯片弹出显示一个文本区域。我想输入文本，然后将帖子保存在日历事件中。

但是，如果我包含上面附加的代码，我不会得到任何结果。

非常感谢任何建议或解决方案。

您可以将 position 和 z-index 属性添加到 textarea 以确保它们堆叠在 .cd-panel-content 之上

.cd-panel-container h1 {
  color: #ffffff;
  font-size: 15px;
  font-weight: 200;
  text-align: center;
  position: absolute;
  top: 25px;
  right: 155px;
  /*display: inline-block;
  overflow: hidden;
  text-indent: 100%;
  white-space: nowrap;*/
}

.cd-panel-container h1:before {
  content: ' ';
  width: 120px;
  display: block;
  border: 1.5px solid #00DED4;
  border-radius: 2px;
  -webkit-border-radius: 4px;
  -moz-border-radius: 4px;
  box-shadow: inset 0 1px 1px rgba(0, 0, 0, .05);
  -webkit-box-shadow: inset 0 1px 1px rgba(0, 0, 0, .05);
  -moz-box-shadow: inset 0 1px 1px rgba(0, 0, 0, .05);
}
