在CSS Cookie同意弹出窗口内对齐关闭按钮。

Question

我有一个cookie同意弹出窗口，我在其中添加了一个关闭X按钮。 我需要将按钮对齐在弹出窗口的中间，但按钮偏离了中心。 我知道我可以设置一个margin-top来解决这个问题，但我认为这不是正确的解决方法。

这样写，即使你有多行文字，也是居中的。

.cookiealert.show {
  opacity: 1;
  visibility: visible;
  transform: translateY(0%);
  transition-delay: 1000ms;
}
.alert{
      position: relative;
    padding: .75rem 1.25rem;
    margin-bottom: 1rem;
    border: 1px solid transparent;
    border-radius: .25rem;
}


.cookiealert {
    font-size: 14px;
    bottom: 0;
    left: 0;
    width: 420px;
    margin-left: 20px;
    z-index: 900;
    transition: all 500ms ease-out;
    color: #000;
    background-color: #ecf0f1;
}

.cookiealert.show {
    opacity: 1;
    visibility: visible;
    transform: translateY(0%);
    transition-delay: 1000ms;
}

.cookiealert a {
    text-decoration: underline
}

.cookiealert .acceptcookies {
  position: absolute;
  top: 0;
  bottom: 0;
  height: 12px;
  margin-top: auto;
  margin-bottom: auto;
  right: 10px;
}

.acceptcookies .x {
    display: block;
    position: relative;
    width: 12px;
    height: 13px;
    transition: transform .28s ease-in-out;
    border-color: rgb(255, 255, 255);
}

.acceptcookies .x:hover {
    transform: rotate(90deg);
}

.acceptcookies .x:before {
    content: "";
    position: absolute;
    display: block;
    left: 0;
    right: 0;
    top: 6px; 
    bottom: 0;
    width: 12px;
    height: 0;
    border-top: 1px solid rgba(0,0,0,0.5);
    transform: rotate(45deg);
    transform-origin: center;
}

.acceptcookies .x:after {
    content: "";
    position: absolute;
    display: block;
    left: 0;
    right: 0;
    top: 6px;
    bottom: 0;
    width: 12px;
    height: 0;
    border-top: 1px solid rgba(0,0,0,0.5);
    transform: rotate(-45deg);
    transform-origin: center;
}

你可以修改你的HTML代码，用Flex来对齐 "x "吗？另外，删除 "x"。position: absolute 财产 .cookiealert .acceptcookies

超文本标记语言

<div class="alert cookiealert d-flex" >
   <div> By using our website you agree to our Cookie policy </div>
   <div class="acceptcookies d-flex align-items-center">
      <div class="x"></div>
  </div>
</div>
