Here is how your PR affects size of JS and CSS bundles shipped to the user's browser:

Sections (~23 bytes added 📈 [gzipped])

What is parsed and gzip size?

Parsed Size: Uncompressed size of the JS and CSS files. This much code needs to be parsed and stored in memory.
Gzip Size: Compressed size of the JS and CSS files. This much data needs to be downloaded over network.

This should be the only change I made to this file.

Previously this had box-shadow: none without the ending semi-colon ;. This broke the next line and auto formatting. As soon as i updated this style and added the semi-colon, saving caused auto format to update a lot of indentations and make this look like quite a bit more changes.

Looks good!

it looks like the auto formatter changes are all in conflict with some other changes to the file now
