WordPress no longer supports many old old browsers: https://make.wordpress.org/core/2017/04/23/target-browser-coverage/
This also removes alot of no longer necessary CSS. It served us well, but we are never getting back together with IE8,9,10.
So, in the (paraphrased) words of Taylor Swift:
I remember when we dropped support the first time
Saying, "This is it, I've had enough, " 'cause like
We hadn't seen many users in a month
When you said you needed flexbox. (What?)
Then you postMessage again and say
"IE8, I miss you and I swear I'm gonna change, trust me."
Remember how that lasted for a day?
I say, "I hate the box model, " we break up, you call me, "I love css-grids."
Ooh, we called it off again last night
But ooh, this time I'm telling you, I'm telling you
We are never ever ever supporting IE 8,9,10,
We are never ever ever supporting IE 8,9,10,
You go talk to EDGE, talk to my FIREFOX, talk to CHROME
But we are never ever ever ever getting back together
Like, ever...

When Open Sans was in use, the `300`, `400`, and `600` weights were loaded. `400` is the equivalent of `normal`; however, `bold` is equivalent to `700`, not `600`. With the move to system fonts, we need to be specific rather than relying on the lack of a `700` weight. Not all system fonts include a `600` weight; in those instances, they will use the `bold`/`700` weight.
The WordPress CSS Coding Standards have been updated accordingly.

Leads and contributing developers will now look nicer when focused.
Also, combines adjacent image and text links for the same resource thus
simplifying markup and reducing noise for screen reader users.

We forgot to run `grunt precommit` before [35834] was committed.
This change doesn't need to be backported to the 4.4 branch, as it only affects Chrome < 26, it's really just to clean up the behaviour of `grunt precommit`.

CSSJanus (introduced in [26107]), we had a great time with you, but sadly you don't like our fancy CSS.
RTLCSS is a framework for converting CSS from LTR to RTL, same as CSSJanus, with support for more CSS properties like `transform`, `transition` or multiple box and text shadows.
Changes:
* devDependencies: Remove `grunt-cssjanus`, add `grunt-rtlcss`.
* RTLCSS uses `/* rtl:ignore */` to ignore a rule, switch existing `/* @noflip */` to the new directive.
* RTLCSS supports the `transform` property, means we can remove some ignore rules.
* RTLCSS supports string maps for custom replace rules. This commit includes a rule `import-rtl-stylesheet` which replaces ".css" with "-rtl.css" in URLs.
Notes for core development:
* The file generation task is still `grunt rtl`.
* If you have used `grunt cssjanus` before, use `grunt rtlcss` now.
* Remember the new directive `/* rtl:ignore */`.

`css-clean` (minifies our CSS) has an issue when using multiple backgrounds and background position together. Instead of relying on browser support for multiple backgrounds to display the WP logo as SVG, use the `.svg` CSS class.

The admin CSS was merged in #18314.
After a couple years as it stood,
The mess it had become just was no good.
One day we realized Grunt is pretty cool,
And said "we should use this as our build tool!"
Now we can maintain separate files with ease,
Using @import and cssmin meets all our needs.
Welcome to the future of the WordPress stylesheets,
And thanks to Slick Rick for the beats.
props jorbin for the initial patch.
