[CSS-in-JS] Global style reset with `emotion` #5122

thompsongl · 2021-09-01T17:15:04Z

Summary

Replacing the Sass global reset file with a 1:1 conversion using Global from @emtion/react
Enabled in the docs; try to find any differences as compared to the production site 🕵️

Diff of the CSS vs. emotion output can be seen in this gist. Note that there are prefixing differences because emotion uses stylis for preprocessing.

This PR also changes the isDefaultTheme utility to isLegacyTheme.

src/global_styling/mixins/_typography.ts

+
+// Our base fonts
+
+export const useEuiFont = () => {


Thinking that we should also provide non-hook versions of these utilities that do not use useEuiTheme directly, but accept a theme parameter. This style of hook can then just consume that function and layer on context awareness.

I still think this is a good idea, but I'm going to do a follow-up PR because there are several other hooks that could use the same two-step treatment.

Notable omissions from the diff gist:

-moz-selection: Legacy; no longer required (https://developer.mozilla.org/en-US/docs/Web/CSS/::selection#syntax)
scrollbar-color: Only supported by Firefox, but styles appear correct without it (https://developer.mozilla.org/en-US/docs/Web/CSS/scrollbar-color)
~~Still researching missing font-family values~~

Still researching missing font-family values

Because I removed those 😆 and reduced the font-family stack to a much smaller, necessary stack.

Oh wow good thing I haven't actually spent any time looking into yet, then 😌

Opening this up for review. @cchaos let's decide what to do with the various variables that don't (yet) exist in the JS theme that the global file relies on.

Issues

I'm just documenting issues as I'm finding them in the diff (I haven't looked at the new reset file yet), not delegating anyone to fix unless you know how to.

1. The compile order is now backwards. It seems the reset is coming in after the component styles.

This is clear in the example of input focus rings.

Correct

Incorrect (this PR)

2. Shouldn't be converting colors from hex to RGB

This is apparent in the Diff (but I see different results in the Dev Console locally).

I think we'll need to add .hex() to any colors we want in hex. Chroma deals in rgba (from @thompsongl)

We may want to think on this one a bit then...

3. Stripping out quotes from font-family 👍

Outdated

This is also happening in the Diff but not locally. But certain font families require the quotes to ensure it's finding the right one. I don't think this conversion is going to work as expected.

4. Using `calc`s for negative values 👍

Outdated

Not sure if this is truly an issue, but just an oddity to point out. We should maybe look into the performance between straight values and `calc()`.

5. `stylis` seems to be wrong right with its prefixing 🤦‍♀️

Outdated

For example `::-moz-selection` is absolutely necessary. Compare:

Correct

Incorrect (this PR)

Another example is checking for experimental flags like content: none which is apparently not supported by any browser, yet it removed the previous content: '' because it just saw two duplicate properties.

6. Linter vs compiled CSS

This is just an observation, not necessarily an issue, but it looks like it will convert single quotes to double, but our Sass linter requires single quotes, so it just feels odd that we have reverse linter of what gets compiled. The same goes for the appending of px to 0 values.

The compile order is now backwards. It seems the reset is coming in after the component styles.

Not entirely sure how to solve this one yet. Now that the global styles are injected after the static css file loads, we may need something like CacheProvider to specify where to inject the globals (i.e., before the static file). Note that this will not be a problem once EUI components are converted; global styles are always injected before non-global styles when done via Emotion.

Default will mean something different when Amsterdam becomes default so I want to head this off now by checking for “Legacy”

though one last think you might want to check is the TS by changing the app_view.js to .tsx

Looking at this but the imported png files cause the build to break

We don't have to actually keep it converted to TS, i just wanted you to check the provider in a TS file. When I converted I was getting a TS error around the Provider. But as I just tried again, I'm not seeing one.

thompsongl · 2021-09-30T21:51:28Z

Oh I see. No TS errors regarding Providers in that file.

Added docs for EuiProvider, although the location is an afterthought at this point. Will likely refactor after #5227 and after a decision is made on the location of EuiThemeProvider (likely moves from services/ to components/).
