如何使用 Flexbox 对齐 HTML 中的项目

Question

我希望我的项目按特定顺序放置，以便 title（带有版权段落的标题）位于页面中间的“关于”部分的中心，不会被填满我的页面的一半...我尝试使用 flex-basis 以便我可以为每个项目指定特定的宽度，但似乎没有用，有什么想法吗？这是页脚部分的代码，我对导航栏和页脚都有这个问题，但我想如果它适用于一个它通常会起作用 还有 PM ：我不知道为什么大多数 html 代码不显示 sn-p ，这是它的外观图像https://imgur.com/4xXP36C

HTML 代码：

.flex {
  display: flex;
  justify-content: center;
  align-items: center;
  flex-direction: row;
  height: 100%;
}

.container {
  max-width: auto;
  margin: 0 auto;
  overflow: auto;
  padding: 0 40px;
  align-self: start;

}

.bg-dark,
.btn-dark {
  background-color: var(--dark-color);
  color: #fff;
}
.footer .box a{

  margin: 0 5px;
}
.lead {
  font-size: 20px;
}
.py-1 {
  padding: 1rem 0;
}

        </div>
     </div>

请根据您的要求在下面找到更新的代码如下：-

1. flex 中的所有三列都采用相同的宽度 (33%)
2. 可选：链接删除列表样式并右对齐以获得更好的用户界面

.flex {
  color: white;
  display: flex;
  justify-content: center;
  align-items: center;
  flex-direction: row;
  height: 100%;
}

.container {
  max-width: auto;
  margin: 0 auto;
  overflow: auto;
  padding: 0 40px;
  align-self: start;
  
}

.flex-basis-3{
  flex-basis: 33%
}

.text-center{
  text-align: center
}

.text-right{
  text-align: right
}

.no-list{
  list-style: none;
}

.bg-dark,
.btn-dark {
  background-color: var(--dark-color);
  color: #000;
}
.footer .box a{
  margin: 0;
}
.lead {
  font-size: 20px;
}
.py-1 {
  padding: 1rem 0;
}
