如何以固定宽度将 div 中的文本居中？

Question

我正在尝试将具有设置宽度的 div 中的文本居中。如果我不这样做，我不会设置文本中心的宽度。我需要设置宽度，因为它会影响较大容器的大小，我希望容器大小相同。

我试过在上面放一个包装纸并将左右边距设置为自动。我已经直接在上面试过了。我试过 text-align: center on it and on a wrapper.

HTML

<div class = "br2 flex flex-row flex-wrap">
  <div class="u-all-out"> 
                      <a class = " flex br5 bg-yellow shadow-1 center flex-col hover-bblue grow hover-ul u-all-in" href="">
                          <div class = "flex">
                              <img class="xbig-icon br5 mb2" id = "train_img_1">
                          </div>
                          <h4 class =" dark-gray items-center hover-bblue w-train-desc" id = "train_title_1"> Here is something</h4>
                          <h6 class ="flex bright-blue items-center hover-bblue rm-mb rm-mt italic hover-ul">Start here</h6>
                      </a>
                  </div>
  <div class="u-all-out">
                    <a class = " flex br5 bg-yellow shadow-1 center flex-col hover-bblue grow hover-ul u-all-in" href="">
                        <div class = "flex">
                            <img class="xbig-icon br5 mb2" id = "train_img_2">
                        </div>
                        <h4 class ="dark-gray items-center hover-bblue w-train-desc" id = "train_title_2"> Here is another</h4>
                        <h6 class ="flex bright-blue items-center hover-bblue rm-mb rm-mt italic hover-ul">Start here</h6>
                    </a>
                </div>
</div>

CSS


.bg-yellow {
  background-color: yellow;
}
.u-all-in {
    padding: 4rem;
}
.u-all-out {
    padding: 3%
}
.flex {
  display: flex;
}
.flex-col {
  flex-direction: column;
}
.flex-row {
  flex-direction: row;
}
.flex-wrap {
  flex-wrap: wrap;
}
.items-center {
  align-items: center;
}
.grow { 
  transition: all .8s ease; 
}
.br5 {
  border-radius: .5em;
}
.br2 {
  border-radius: .2em;
}
.xbig-icon {
  width: 10rem;
  height: 10rem;
}
.center {
  justify-content: center;
  align-items: center;
}
.dark-gray, h1, h2, h3 {
  color: #383A42;/*#2B2C34;*/
}
.bright-blue {
  color: #1ABFD8;
}
.hover-ul:hover > .hover-ul  {
  border-bottom: 1px solid;
}

.hover-bblue:hover > .hover-bblue  {
  color: #1ABFD8;
}
.w-train-desc {
    margin-right: auto;
    margin-left: auto;
    width: 220px;
    display: inline-block;
}

由于悬停效果的编码方式，我宁愿不需要包装器。但这让我发疯。我想要的只是设置 div/h4 的宽度并将文本居中 div/h4.

提前致谢！

Answer 2

text-align: center; 到 .w-train-desc class 完成了工作...或者我没听懂你的意思？

Answer 3

我错过了什么吗？ - 当我将文本居中对齐时，它起作用了。

.w-train-desc {
    width: 220px;
    text-align:center;
}

我在 codepen 中似乎没有运行按钮，但如果我检查它，它可以工作
