为什么我的专栏内容从不同的高度开始?

Why are my columns' contents starting at different heights?

我读到不应使用表格作为布局方式,而应使用 CSS 进行所有样式设置,因此我尝试了我能想到的最基本的方法来 模仿 个表格,使用 CSS 多列布局。

我创建了一个CodePen来说明这个问题。可以看到,两栏内容的起始高度不同,不明白为什么。

.skill-explanation {
  -webkit-column-count: 2;
  -moz-column-count: 2;
  -ms-column-count: 2;
  column-count: 2;
}

.align-left {
  text-align: left;
}

.align-right {
  text-align: right;
}
<div class="skill-explanation">
  <div class="align-right">
    <p>&#9733;&#9734;&#9734;&#9734; &#8210; <br>
    &#9733;&#9733;&#9734;&#9734; &#8210; <br> 
    &#9733;&#9733;&#9733;&#9734; &#8210; <br> 
    &#9733;&#9733;&#9733;&#9733; &#8210;
   </p>
  </div>
  <div class="align-left">
    <p>I can put it into context and am able to use it's basics <br>
    intermediate knowledge, used several times <br>
    good undestanding, used frequently <br>
    deep understanding, used on a daily basis
    </p>
  </div>
</div>

我想就此 post 提供更新,以防有人无意中发现它。 1) 标记的答案是我的改进,但我仍然觉得它不直观,因为它使用默认的 flex 流,将主轴放在水平方向上。
从逻辑的角度来看,这应该是列。

因此这里有一个更新的解决方案,这是最简单直观的(至少在我看来):

.center-wrapper {
  margin: 0 auto;
  display:table;
}

.skill-explanation {
  list-style: none;
}

.rating {
}

.skill {
}

.skill-item {
  list-style: none;
}
<div class="center-wrapper" <ul class="skill-explanation">
  <li class="skill-item">
    <span class="rating">&#9733;&#9734;&#9734;&#9734; &#8210;</span>
    <span class="skill">I can put it into context and am able to use it's basics</span>
  </li>
  <li class="skill-item">
    <span class="rating">&#9733;&#9733;&#9734;&#9734; &#8210;</span>
    <span class="skill"></span>
    intermediate knowledge, used several times
  </li>
  <li class="skill-item">
    <span class="rating"> &#9733;&#9733;&#9733;&#9734; &#8210;</span>
    <span class="skill"></span>
    good undestanding, used frequently
  </li>

  <li class="skill-item">
    <span class="rating">&#9733;&#9733;&#9733;&#9733; &#8210;</span>
    <span class="skill"></span>
    deep understanding, used on a daily basis
  </li>
  </ul>
</div>

您可以将 padding: 1px 0 添加到 .align-left.align-right 这两个容器中。这样一来,p 标签的默认顶部和底部边距就保留在它们的容器内,不会像您的代码笔那样由于折叠边距而导致任何垂直偏移。

编辑 如果您想使用已有的代码。删除设置为浏览器的段落 "p" 标记的边距。然后将行高设置为你想要的高度。
原始答案
如果你想轻松地排列你的项目,你会想要使用类似 flexbox 的东西。您可能还想设置行高,以确保您的 unicode 图标和文本正确对齐
这将允许您完全控制文本和图标对齐的位置。 More info on flexbox at W3schools

p{
  margin: 0;
  line-height: 1.5em;
}

弹性框示例:

.skill-explanation {
  display: flex;
  align-items: center;
}
.align-left, .align-right {
  line-height: 1.5rem;
}

.skill-explanation {
  display: flex;
  align-items: center;
}
.align-left, .align-right {
  line-height: 1.5em;
}
<div class="skill-explanation">
          <div class="align-right">   
            <p>&#9733;&#9734;&#9734;&#9734; &#8210; <br>
              &#9733;&#9733;&#9734;&#9734; &#8210; <br>
              &#9733;&#9733;&#9733;&#9734; &#8210; <br>
              &#9733;&#9733;&#9733;&#9733; &#8210;</p>
          </div>
          <div class="align-left">
            <p>I can put it into context and am able to use it's basics <br>
              intermediate knowledge, used several times <br>
              good undestanding, used frequently <br>
              deep understanding, used on a daily basis</p>
          </div>
        </div>

但是您最好按照其他人的建议重新访问您的 HTML 代码并将其放入列表中,因为这在语义上更正确并且更易于维护

  <ul>
    <li>&#9733;&#9734;&#9734;&#9734; &#8210; I can put it into context and am able to use it's basics</li>
    <li>&#9733;&#9733;&#9734;&#9734; &#8210; intermediate knowledge, used several times</li>
    <li>&#9733;&#9733;&#9733;&#9734; &#8210; good undestanding, used frequently</li>
    <li>&#9733;&#9733;&#9733;&#9733; &#8210; deep understanding, used on a daily basis</li>
  </ul>

您的问题是 p 元素的边距正在折叠,就像 div 垂直堆叠时一样。 .

但是,你的概念是有缺陷的。您可能真的想将评级与技能相关联

ul.skill-explanation {
  list-style: none;
  padding-left: 0;
}

.skill-item {
  display: flex;
}

.skill-item > div {
  width:50%;
}

.rating {padding-right: 0.5em; 
text-align:right;
}
<ul class="skill-explanation">
  <li class="skill-item">
    <div class="rating">&#9733;&#9734;&#9734;&#9734; &#8210;</div>
    <div class="skill">I can put it into context and am able to use it's basics</div>
  </li>
  <li class="skill-item">
    <div class="rating">&#9733;&#9733;&#9734;&#9734; &#8210;</div>
    <div class="skill">intermediate knowledge, used several times</div>
  </li>
  <li class="skill-item">
    <div class="rating">&#9733;&#9733;&#9733;&#9734; &#8210;</div>
    <div class="skill">good undestanding, used frequently</div>
  </li>

  <li class="skill-item">
    <div class="rating"> &#9733;&#9733;&#9733;&#9733; &#8210;</div>
    <div class="skill">deep understanding, used on a daily basis</div>
  </li>
</ul>
