从底部开始放置网格项 [英] Position grid items starting at the bottom

问题描述

我有一个CSS网格，在此网格文章中可能是博客文章。它们由左侧的图像和右侧的文本组成。

I have a CSS grid and in this grid articles that could be blog posts. They consist of an image on the left and text on the right.

我需要文章从底部开始，以便较新的文章出现在它们的上方。但是，无论我尝试了什么，我都无法让他们从头开始。 align-items：end; 应该可以解决这个问题，但事实并非如此……所以我在这里想念什么？

I need the articles to start at the bottom, so that newer articles appear above them. But I just can't get them to start at the bottom whatever I try it's not working. align-items: end; should do the trick but it doesn't … So what am I missing here?

.blog-Grid {
  display: grid;
}

.post {
  display: grid;
  grid-template-columns: repeat(2, 1fr);
  width: 50%;
  margin: 0 0 10% 15%;
}

<section class="blog-Grid">
  <article class="post">
    <img id="img" src="images/img1.jpeg" alt="">
    <div class="post-text-box">
      <h3 class="post-header"> I'm a header </h3>
      <p class="post-text"> Lorem ipsum text. </p>
    </div>
  </article>
  <article class="post">
    <img id="img" src="images/img2.jpg" alt="">
    <div class="post-text-box">
      <h3 class="post-header"> I'm a header </h3>
      <p class="post-text"> Lorem ipsum text.</p>
    </div>
  </article>
</section>

推荐答案

那么我在这里想念什么？

您忽略了以下事实：默认情况下，HTML元素的高度为 height：自动（请参见下面的参考资料）。这意味着它们就是内容的高度。这意味着没有多余的空间用于垂直对齐。

You're overlooking the fact that HTML elements are, by default, height: auto (see reference below). This means they are the height of their content. This means there is no extra space for vertical alignment.

这里是代码的简化版本。我在容器周围添加了边框。注意高度是如何自动缩小以适合的。

Here is a simplified version of your code. I added a border around the container. Note how the height is automatically "shrink-to-fit".

.blog-Grid {
  display: grid;
  border: 2px solid red;
}

.post {
  display: grid;
  grid-template-columns: repeat(2, 1fr);
}

* {
  margin: 0;
  box-sizing: border-box;
}

<section class="blog-Grid">
  <article class="post">
    <img id="img" src="images/img1.jpeg" alt="">
    <div class="post-text-box">
      <h3 class="post-header"> I'm a header </h3>
      <p class="post-text"> Lorem ipsum text. </p>
    </div>
  </article>
  <article class="post">
    <img id="img" src="images/img2.jpg" alt="">
    <div class="post-text-box">
      <h3 class="post-header"> I'm a header </h3>
      <p class="post-text"> Lorem ipsum text.</p>
    </div>
  </article>
</section>

只需在容器中增加高度即可创建额外的空间。

So, very simply, add height to your container in order to create extra space.

.blog-Grid {
  display: grid;
  height: 100vh;
  align-content: end;
  border: 2px solid red;
}

.post {
  display: grid;
  grid-template-columns: auto 1fr;
  align-items: center;
}

* {
  margin: 0;
  box-sizing: border-box;
}

<section class="blog-Grid">
  <article class="post">
    <img src="http://i.imgur.com/60PVLis.png" width="100" height="100" alt="">
    <div class="post-text-box">
      <h3 class="post-header"> I'm a header </h3>
      <p class="post-text"> Lorem ipsum text. </p>
    </div>
  </article>
  <article class="post">
    <img src="http://i.imgur.com/60PVLis.png" width="100" height="100" alt="">
    <div class="post-text-box">
      <h3 class="post-header"> I'm a header </h3>
      <p class="post-text"> Lorem ipsum text.</p>
    </div>
  </article>
</section>

另请参见：

• 默认情况下，block元素消耗其父级的全部宽度。这种行为不会扩展到高度。


• align-有什么区别？项目与网格布局中的对齐内容？


• justify-自我，对齐项和对齐内容（有关 align-items 与 align-content ）



• Block elements consume the full width of their parent, by default. This behavior does not extend to height.
