使锚标签填充父Flex元素的100%高度和宽度,同时垂直和水平居中

Question

我有一个使用flexbox构建的布局,但有一个方面我似乎无法开始工作.

我有面板,其中有锚标签,我想垂直和水平居中,但我希望锚标签是面板宽度和高度的100%,这样当你点击面板中的任何地方它会链接你,而不是单击链接文本.

这是面板的HTML:

<div class="panel--link panel--one">
    <a href="#" class="link">
        Panel 1
    </a>
</div>

和SCSS:

.panel {
    box-sizing: content-box;
    flex: 1;
    border: 3px solid #fff;
    padding: 0px;
    text-align: center;
}

.panel--link {
    @extend .panel;
    display: flex;  
    flex: 1;
    justify-content: center;
    align-items: center;

    a.link {
        text-decoration: none;
        color: #fff;
        text-transform: uppercase;
        font-weight: 600;
        font-size: 1rem;
        letter-spacing: 3px;
        flex: 1;
    }
}

请参阅我的Codepen了解整个布局,以便您更好地理解它!

Answer 1

不要害怕,让锚定一个弹性箱......

a{
  display: flex;
  justify-content: center;
  align-items: center;
}

你应该添加align-items: stretch到锚的父级.

Answer 2

align-items: center从中取出.content .panel--link并制作.content .panel--link a.link一个flexbox，然后使用以下方法将其垂直对齐：

display: flex;
justify-content: center;
align-items: center;

请参阅下面的演示：

display: flex;
justify-content: center;
align-items: center;

body {
  height: 800px;
}
.main {
  height: 100%;
}
.content {
  height: 100%;
  border: 20px solid #fff;
  display: flex;
  box-sizing: border-box;
}
.content .column {
  flex-direction: column;
  width: 33.33333%;
  background: #374550;
  display: flex;
}
.content .panel,
.content .panel--link {
  box-sizing: content-box;
  flex: 1;
  border: 3px solid #fff;
  padding: 0px;
  text-align: center;
}
.content .panel .logo,
.content .panel--link .logo {
  margin: 7.5% 0px 0% 0%;
  width: 80%;
}
.content .panel .blurb,
.content .panel--link .blurb {
  width: 80%;
  margin: 7.5% auto 0% auto;
}
.content .panel .blurb h1,
.content .panel--link .blurb h1 {
  text-decoration: none;
  color: rgba(255, 255, 255, 0.6);
  font-weight: lighter;
  line-height: 220%;
  font-size: 0.85rem;
  margin: 0px;
}
.content .panel .tel,
.content .panel--link .tel {
  margin: 7.5% auto 5% auto;
}
.content .panel .tel h2,
.content .panel--link .tel h2 {
  text-decoration: none;
  color: #fff;
  font-weight: 500;
  font-size: 1.2rem;
  margin: 0px;
}
.content .panel--link {
  display: flex;
  flex: 1;
  justify-content: center;
  /*align-items: center;*/
  text-align: center;
}
.content .panel--link a.link {
  text-decoration: none;
  color: #fff;
  text-transform: uppercase;
  font-weight: 600;
  font-size: 1rem;
  letter-spacing: 3px;
  flex: 1;
  display: flex;
  justify-content: center;
  align-items: center;
}
@media (max-width: 768px) {
  .content .column--two {
    order: -1;
  }
  .content .column--two .panel--two {
    order: -1;
  }
}
.content .column--two .panel--one {
  flex-grow: 1;
}
.content .column--two .panel--two {
  flex-grow: 2;
  background: #374550;
}
.content .column--two .panel--three {
  flex-grow: 1;
}
