html - 无处不在的大高度

Question

不知何故，图片上的一组相同 block 元素中的一个变得莫名其妙地变大了。图片上显示的样式并未暗示此元素的那种行为。事实上，height 甚至没有为那些 h3 设置。 Browser screenshot

html是

<section class="about-us">
  <div class="wrapper clearfix">
    <h2 class="about-us-heading section-heading red-black-stressing-line-at-left">About Us</h2>
    <p class="about-us-statement section-saying about-us-saying">This is who we are - or at least who we strive to be...</p>
    <div class="about-more">
      <p class="about-saying">If you can't explain it simply, you don't understand it enough.</p>
      <a href="#" class="about-more-link">The more you know</a>
    </div>
    <div class="about-work-details">
      <h3 class="about-details-heading typography-icon">Typography</h3>
      <p class="about-details-text">...</p>
    </div>
    <div class="about-work-details">
      <h3 class="about-details-heading curve-with-dots-icon">Full icon set</h3>
      <p class="about-details-text">...</p>
    </div>
    <div class="about-work-details">
      <h3 class="about-details-heading triangular-ruler-icon">Accurate</h3>
      <p class="about-details-text">...</p>
    </div>
  </div>
</section>

三个相同的 div.about-work-details 元素。

默认的CSS是

.about-us{
   background-color: #fff;
   position: relative;
}

.about-us-heading{
  color: #272d32;
}

.about-us-statement{
  color: #4e5860;
  margin-bottom: 3.9em;
}

.about-more{
  width: 16.875em;
  float:left;
  margin-right: 1.875em;
}

.about-saying{
  font-family: "Open Sans", sans-serif;
  font-size: 1.75em;
  line-height: 1.4285;
  color: #4e5860;
}

.about-more-link{
  display: inline-block;
  font-family: "Raleway", sans-serif;
  line-height: .77;
  padding: 1em 2.625em 1em 1.25em;
  text-decoration: none;
  font-weight: 600;
  color: #fff;
  text-transform: uppercase;
  background: #ff3c1f url(../images/left-arrow.gif) 12.7em .95em no-repeat;
  margin-top: 4.25em;
  transition: background-color 0.5s;
}

.about-work-details{
  width: 16.875em;
  float:left;
  margin-right: 1.685em;
  margin-bottom: 8.1875em;
  position: relative;
  min-height: 16.875em;
  border: 1px solid #edeff2;
}

.about-work-details:last-of-type{
  margin-right: 0;
}

.about-details-heading{
  font-family: "Open Sans", sans-serif;
  font-weight: 700;
  font-size: 1.25em;
  color: #303030;
  text-transform: uppercase;
  padding: 0.85em 0 1em 3em;
  margin: 1.70em 0 0 1em;
}

媒体查询修改

@media screen and (max-width: 860px){

  .about-work-details{
    width: 70%;
    margin: 3em auto;
    min-height: 0;
    float: none;
  }

  .about-us{
    padding-bottom: 1px;
  }

  .about-work-details:last-of-type {
    margin-right: auto;
  }

}

Answer 1

似乎是一个 float 元素行为问题。

• 尝试从 .about-more 中删除/注释 float:left;。
