Does it need to hold on until The created of one Million article?

@Cwek Maybe. However, I think, if we hold it on until the creation of one Million article, would it be too late?

My understanding is that you could temporary change the logo change via CSS yourself, similar to https://phabricator.wikimedia.org/T186455 in https://cs.wikipedia.org/w/index.php?title=MediaWiki%3ACommon.css&type=revision&diff=15844030&oldid=15540856

So this might not need a code change in Gerrit.

Because SWAT has deploy windows, patch cannot be deployed in time. The delay is likely to be between hours and days.

The logo file can be set only one, it can't be changed by the language of interface. Only CSS Hacking is the solution.

maybe we need to change Common.js locally.

These two versions should be the logo used:
for zh-hans, zh-cn, and zh-sg (chinese - simplified)

for the rest, please use this version (chinese traditional)
https://commons.wikimedia.org/wiki/File:Margined_-_Chinese_wikipedia_1M_logo_-_%E7%87%83%E7%81%AFver_trad_-_CelPhi.svg

The reason behind this is that these two are "margined", and align better with the current logo slot. Since this milestone logo is slightly taller, we need to pull the side nav bar down by 20px for all the skins that has a logo.

Check out this tool I wrote for all the css that needs to be changed. Applicable for all the user languages and skins.

Please note that there is one more piece of puzzle on the globe. You will still need to change the image file, adding text is not enough.
