本质上,我需要图像和标题位于屏幕中央,但我还需要图像可单击并打开链接。我相信我有正确的代码来做到这一点,但我仍然遇到这两个问题。图像也有两种不同的尺寸,因此也变得很困难。我只是尝试将红色药丸变小,将蓝色药丸变大(相对于它们的原始大小)。

不必担心其他 3 个图像的背景关键帧。我只需要有关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,但仍然遇到相同的错误。我尝试过将图像调整为不同的尺寸,尝试过不同的居中技术,但似乎无法实现。

我对您的目标有所猜测,但是您不需要居中对齐图像容器吗?我已在 #background 选择器上执行了此操作。

然后,我将调整大小的职责移至锚点,并将其显示属性设置为 inline-block。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并且应该避免。

图像大小不等。您可以使用 CSS 以多种方式处理该问题,但最好的解决方法是调整它们的大小以匹配。我会将较大的尺寸缩小到与较小的尺寸相同。

仅供参考,您的样式元素位于 head 和 body 元素之外。这是无效的 HTML。将其放入 head 元素内。

此外,中心元素很长已弃用,不应使用。
