div 不是所有内容的中心

Question

这是我的 HTML 代码：

.kobel_perm {
  height: auto;
  border-radius: 5px;
  box-shadow: 1px 1px 5px #0d0d0d;
}

.kobel_input_cont {
 justify-content: center;
 align-items:center;
}

.kobelK {
 padding: 5px;
 background-image: linear-gradient(to right, #7ef6a9, #86a8e7);
 -webkit-background-clip: text;
 -webkit-text-fill-color: transparent;
}

.kobel_perm input {
    width: 95%;
    padding: 12px 20px;
    margin: 8px 0;
    display: inline-block;
    border: 1px solid #ccc;
    border-radius: 4px;
    box-sizing: border-box;
  background-color: #212121;
  color: #ffffff;
}

.kobel_perm input::placeholder {
 color: #ffffff;
}

.kobel_perm input[type=button] {
 cursor: pointer;
 border: 1px solid #7ef6a9;
}

.kobel_perm input[type=button]:hover, .kobel_in input[type=button]:focus {
 border: 1px solid #7ef6a9;
 animation: color_change 1s;
 background-color: #7ef6a9;
 color: #212121;
}

@-webkit-keyframes color_change {
 0% {
  background-color: #00251d1d;
  color: #ffffff;
 }
 100% {
  background-color: #7ef6a9;
  color: #212121;
 }
}

<div class='kobel_perm'>
    <p class="kobelK">Kobeltage</p>
    <div class="kobel_input_cont">
         <input type="text" id="kobel_weekday" name="kobel_weekday" placeholder="Wochentag">
         <input type="text" id="kobel_date" name="kobel_date" placeholder="Datum">
         <input type="text" id="kobel_topic" name="kobel_topic" placeholder="Thema">
         <input type="text" id="kobel_host" name="kobel_host" placeholder="Kobelwirte">
         <input type="button" value="Kobel hinzufügen" onclick="addKobel()">
         <input type="button" value="Kobel entfernen" onclick="removeKobel()">
      </div>
 </div>

当您查看图像时，您会看到输入未水平居中。我寻找一种方法来解决这个问题，因为我只想将输入居中，而不是上面的文本 "Kobeltage"。

Answer 1

您正在寻找：text-align:center

只需将属性添加到包含您的输入的 div 中：

.kobel_input_cont {
    justify-content: center;
    align-items:center;
    text-align:center;

}

Answer 2

您需要将占位符居中吗？用伪元素居中，像这样：

.kobel_perm {
  height: auto;
  border-radius: 5px;
  box-shadow: 1px 1px 5px #0d0d0d;
}

.kobel_input_cont {
 justify-content: center;
 align-items:center;
}

.kobelK {
 padding: 5px;
 background-image: linear-gradient(to right, #7ef6a9, #86a8e7);
 -webkit-background-clip: text;
 -webkit-text-fill-color: transparent;
}

.kobel_perm input {
    width: 95%;
    padding: 12px 20px;
    margin: 8px 0;
    display: inline-block;
    border: 1px solid #ccc;
    border-radius: 4px;
    box-sizing: border-box;
  background-color: #212121;
  color: #ffffff;
}

.kobel_perm input::placeholder {
 color: #ffffff;
}

.kobel_perm input[type=button] {
 cursor: pointer;
 border: 1px solid #7ef6a9;
}

.kobel_perm input[type=button]:hover, .kobel_in input[type=button]:focus {
 border: 1px solid #7ef6a9;
 animation: color_change 1s;
 background-color: #7ef6a9;
 color: #212121;
}

@-webkit-keyframes color_change {
 0% {
  background-color: #00251d1d;
  color: #ffffff;
 }
 100% {
  background-color: #7ef6a9;
  color: #212121;
 }
}

::-webkit-input-placeholder {
   text-align: center;
}

:-moz-placeholder { /* Firefox 18- */
   text-align: center;  
}

::-moz-placeholder {  /* Firefox 19+ */
   text-align: center;  
}

:-ms-input-placeholder {  
   text-align: center; 
}

<div class='kobel_perm'>
                      <p class="kobelK">Kobeltage</p>
                      <div class="kobel_input_cont">
                        <input type="text" id="kobel_weekday" name="kobel_weekday" placeholder="Wochentag">
                        <input type="text" id="kobel_date" name="kobel_date" placeholder="Datum">
                        <input type="text" id="kobel_topic" name="kobel_topic" placeholder="Thema">
                        <input type="text" id="kobel_host" name="kobel_host" placeholder="Kobelwirte">
                        <input type="button" value="Kobel hinzufügen" onclick="addKobel()">
                        <input type="button" value="Kobel entfernen" onclick="removeKobel()">
                      </div>
                  </div>

Answer 3

如果你想在中心设置占位符那么你只需要写，

::-webkit-input-placeholder {
   text-align: center;
}

这将使您的占位符居中

.kobel_perm {
  height: auto;
  border-radius: 5px;
  box-shadow: 1px 1px 5px #0d0d0d;
}

.kobel_input_cont {
 justify-content: center;
 align-items:center;
}

.kobelK {
 padding: 5px;
 background-image: linear-gradient(to right, #7ef6a9, #86a8e7);
 -webkit-background-clip: text;
 -webkit-text-fill-color: transparent;
}

.kobel_perm input {
    width: 95%;
    padding: 12px 20px;
    margin: 8px 0;
    display: inline-block;
    border: 1px solid #ccc;
    border-radius: 4px;
    box-sizing: border-box;
  background-color: #212121;
  color: #ffffff;
}

.kobel_perm input::placeholder {
 color: #ffffff;
}

.kobel_perm input[type=button] {
 cursor: pointer;
 border: 1px solid #7ef6a9;
}

.kobel_perm input[type=button]:hover, .kobel_in input[type=button]:focus {
 border: 1px solid #7ef6a9;
 animation: color_change 1s;
 background-color: #7ef6a9;
 color: #212121;
}
::-webkit-input-placeholder {
   text-align: center;
}

@-webkit-keyframes color_change {
 0% {
  background-color: #00251d1d;
  color: #ffffff;
 }
 100% {
  background-color: #7ef6a9;
  color: #212121;
 }
}

<div class='kobel_perm'>
                      <p class="kobelK">Kobeltage</p>
                      <div class="kobel_input_cont">
                        <input type="text" id="kobel_weekday" name="kobel_weekday" placeholder="Wochentag">
                        <input type="text" id="kobel_date" name="kobel_date" placeholder="Datum">
                        <input type="text" id="kobel_topic" name="kobel_topic" placeholder="Thema">
                        <input type="text" id="kobel_host" name="kobel_host" placeholder="Kobelwirte">
                        <input type="button" value="Kobel hinzufügen" onclick="addKobel()">
                        <input type="button" value="Kobel entfernen" onclick="removeKobel()">
                      </div>
                  </div>
