When declaring the 'from' and 'to' values, a space is inserted after the first and before the last curly bracket. Why?

Is this a convention, personal preference, or a functional necessity?

Hi Dot,

It is just for better readability.

It is a bit of the first two. It just makes the code a little cleaner and easier to read. In CSS, whitespace (spaces, tabs, enters, etc) is ignored by the browser.

Some sites even put their code through 'minifiers' that take all the extra spaces out to make the file as small as possible. But only after the developers don't have to read it anymore!

Thanks Tom and Hugo! That makes sense.
