White text on a black background, or “dark mode,” makes the eye work harder and open wider, since it needs to absorb more light. When this happens, the white letters can bleed into the black background and cause the text to blur, which is also known as the “halation” effect.

是我 out 了吗?
每个抖音作者都会有数条视频,而每条视频下又会有数条评论。估计会有数百个抖音作者,千万条评论,读写会比较频繁,可能会日增几万条或者十万条数据,老板想把这些评论信息都存到数据库(评论者抖音号、评论内容,评论时间,对应的视频 id )。
我目前想到的是存到 MongoDB,每一个作者抖音号是一个集合名字,集合里就是这个作者下所有视频的评论(每条评论里会包含对应的视频 id );
