页面底部的大空白 space
Big blank space at the bottom of page
我遇到了这个问题，当我在flexbox列中添加背景图片时，我可以看到底部有一个很大的空白space。我试图检查页面，但找不到问题所在。我不知道如何解决这个问题，我想做的是删除空白 space 或者让图片一直下降。

One of the most urgent issues of our time, climate change has widespread implications — from the exacerbation of
poverty, to the breakdown of infrastructure, to the loss of environmental, political, economic and social security.
Experts agree that climate change threatens to set back development efforts by decades, placing least developed countries
and already-vulnerable populations in an even more precarious position.

The latest Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5), signed
off by almost 200 nations, concludes with 95% certainty or more that humans have caused the majority
of climate change since the 1950s. It predicts global surface temperature to continue to rise, along
with increased sea level rise, melting of glaciers and ice sheets, acidification of oceans, increase
in the intensity of tropical storms and changes in precipitation patterns.

As a global community, we all have a role in developing and implementing solutions toward significant
transformation in our development patterns. It requires not only a shift in awareness and accountability
for our own individual choices but in a social, political and economic shift towards enabling conditions

由于没有图片，有点难看，但我会添加一张图片：
问题在这里：
.row {
flex: 50%;
padding: 3em; <---- This line
padding-left: 15em;
}
您要在行元素周围添加额外的填充，包括底部。删除此填充后，屏幕底部的 space 消失了。
这是一个工作演示：https://codepen.io/Lissy93/pen/yLvBJLe
提示：我建议使用开发者工具，将元素选择器悬停在 space 上，它会准确显示是哪个元素导致的，并显示它是否为（绿色）填充和（橙色）边距。
我在底部没有看到任何 space。我在 linux 上使用 firefox。
