我正在学习 CSS 并创建响应式网页。我已经开始从事媒体查询工作。当我最大化屏幕时，一切都按预期工作，但是当我缩小它的大小时，不适合视口(viewport)的内容被隐藏，并且空白保留在它的位置。可以看到该空间将屏幕滚动到一边。为什么出现那个空间而不是其余内容？我也不明白为什么我的内容不适合屏幕，因为我使用的是元素宽度的百分比值。我的代码如下:

最佳答案

其实并没有隐藏。标题中的链接恰好具有接近白色的颜色，对比度非常低。当标题的内容比视口(viewport)宽时，它们会溢出标题的右侧。

最简单的解决方案是将 flex-wrap:wrap 赋予 header，但我建议使用媒体查询来覆盖 display:flex 代替(为了更好的向后兼容性)。
