CSS - 按钮对齐不正确

Question

无论我做什么（现在几个小时），我都无法将 <div class="kafelek"> 彼此相邻对齐；目前的代码如下所示：

body {
  background-color: #003C3D;
}

.header {
  text-align: center;
  align-content: center;
  padding: 20px;
  font-family: 'Open Sans';
  font-size: 24px;
  color: #C3CECB;
}

#headerlogo {
  width: 400px;
  height: auto;
  object-fit: cover;
  position: absolute;
  top: 20px;
  left: 50%;
  transform: translateX(-50%);
  animation: slide-in 1s ease-in-out forwards;
}

@keyframes slide-in {
  from {
    top: -100px;
  }
  to {
    top: 20px;
  }
}

.pre1 {
  width: 50%;
  text-align: center;
  align-content: center;
  font-family: 'Open Sans';
  font-size: 24px;
  color: #C3CECB;
  float: left;
}

.pre2 {
  width: 50%;
  text-align: center;
  align-content: center;
  font-family: 'Open Sans';
  font-size: 24px;
  color: #C3CECB;
  float: right;
}

.alignkafel1,
.alignkafel2 {
  display: flex;
  flex-wrap: wrap;
}

.row {
  display: flex;
}

.kolumna {
  display: inline-block;
  width: 48%;
  font-family: 'Open Sans';
  color: #C3CECB;
  text-align: center;
  display: flex;
  flex-wrap: wrap;
  justify-content: space-between;
}

.kolumna:first-child {
  margin-right: 0px;
}

.kolumna:last-child {
  margin-left: 0px;
}

.row:after {
  content: "";
  display: table;
  clear: both;
}

@media screen and (max-width: 800px) {
  .kolumna {
    width: 100%;
    align-content: center;
  }
}

kolumna2 {
  display: inline-block;
  width: 48%;
  font-family: 'Open Sans';
  color: #C3CECB;
  text-align: center;
  display: flex;
  flex-wrap: wrap;
  justify-content: space-between;
}

.kolumna2:first-child {
  margin-right: 0px;
}

.kolumna2:last-child {
  margin-left: 0px;
}

@media screen and (max-width: 800px) {
  .kolumna2 {
    width: 100%;
    align-content: center;
  }
}

.kafelek {
  background-color: #006D57;
  border-radius: 10px;
  text-align: center;
  height: 100px;
  font-family: 'Open Sans';
  font-size: 20px;
  color: #C3CECB;
  margin: 5px;
  margin-top: 50px;
  margin-right: 50px;
  margin-bottom: 1px;
  margin-left: 30px;
  display: flex;
  align-items: center;
  justify-content: center;
}

@media screen and (max-width: 800px) {
  .kafelek {
    display: flex;
    justify-content: center;
  }
}

.kafelek:hover {
  border: 2px solid #7EDF00;
  transition: 0.3s;
  cursor: pointer;
}

<div class="header">
  <img src="" img id="headerlogo" />
  <br /> <br /> Centrum zgłoszeniowe AOK
</div>

<div class="pre1"> Delivery Support </div>
<div class="pre2"> Middle Mile</div>



<div class="alignkafel1">
  <div class="kafelek">Koszta Dodatkowe</div>
  <div class="kafelek">COMING SOON</div>
  <div class="kafelek">COMING SOON</div>
  <div class="kafelek">COMING SOON</div>
</div>

<div class="alignkafel2">
  <div class="kafelek">COMING SOON</div>
  <div class="kafelek">COMING SOON</div>
  <div class="kafelek">COMING SOON</div>
  <div class="kafelek">COMING SOON</div>
</div>

我一直在尝试多种选择，但最终一切都变得一团糟。

它看起来像这样： 网站混乱

我希望 8 个 .kafelek （即按钮）中的每一个都在 1 行中彼此完美对齐，并且正确居中以与 .pre1 和 .pre2 对齐

请帮忙;-;

Answer 1

按钮容器的宽度为 0，这会阻止弹性盒正常工作。添加宽度可以解决问题。

.alignkafel1,
.alignkafel2 {
  display: flex;
  flex-wrap: wrap;
  justify-content: space-between;
  width: 60%;
  margin: 0 auto;
}

我添加了 60% 的宽度，以使按钮与上面的 pre 大致对齐。目前，pre 设置了 float 属性。理想情况下，您希望父容器强制执行页面内容的边界并避免使用 float css 属性。
