CSS - rem and em
[this is a draft]
Which unit to use, rem, em or even px (just to mention the most common units) when writing CSS seems to be an ongoing discussion. For people entering the space of web development the hurdle just gets higher, the complexity is continuously growing. There are
more units than ever, I counted 21, there is more sites to learn from. It is not easy to figure out where and how to start.
I will try to analyze this a bit applying what I know and have learnt over the last 25 years of web development.
