需要帮助使内容居中并使图像链接可点击
Need help centering content and making image links clickable
问:
从本质上讲,我需要图像和标题在屏幕中居中,但我还需要图像可点击并打开链接。我相信我有正确的代码可以做到这一点,但我仍然遇到这两个问题。图像也有 2 种不同的尺寸,因此这也使它变得困难。我只是试着把红色药丸弄得更小,把蓝色药丸弄得更大,相对于它们原来的大小。
不要担心其他 3 张图像的背景关键帧。我只需要标题居中以及红色和蓝色药丸图像的帮助。
我尝试使用在线代码,但我仍然遇到相同的错误。我尝试过将图像调整为不同的大小,我尝试过不同的居中技术,但似乎无法理解。

答:
我有点猜到你的目标,但你不需要将图像容器居中对齐吗?我已经在选择器上这样做了。#background
然后,我将大小调整任务转移到锚点,并将其 display 属性设置为 。这迫使它们完全包含图像(请参阅为什么锚标记不采用其包含元素的高度和宽度)。我还将图像的最大宽度设置为 100%。这一切都是在CSS中完成的,因为内联样式效率低下,需要避免。inline-block
图像大小不相等。您可以使用 CSS 以多种方式处理它,但最好的解决方法是调整它们的大小以匹配。我会将较大的一个减小到与较小的大小相同。
仅供参考,您的风格元素在头部和身体元素之外。这是无效的 HTML。把它放在头部元件里面。
此外,center 元素早已弃用,不应使用。

它可能就像在标记中添加不同的 flex
容器一样简单,一个在主容器上,一个用于保存锚点/图像。
这里的 和 容器都设置为 while is 。然后,您可以使用 CSS 调整图像的宽度,并正确调整它们的比例。main
.pills
flex
main
flex-direction: column
main {
flex-direction: column;
}
main, .pills {
display: flex;
align-items: center;
justify-content: flex-start;
}
img { width: 100px; aspect-ratio: 3 / 2; }
<main>
