Consistent disabled state for all components #19343

Open LorenzHenk opened 4 years ago

LorenzHenk commented 4 years ago

At the moment, the disabled color of the slider is theme.palette.grey[400]. Other inputs use theme.palette.action.disabled (also used e.g. here) and theme.palette.text.disabled.

The Slider should use theme.palette.action.disabled as well.

Current Behavior 😯

The Slider uses theme.palette.grey[400].

Expected Behavior πŸ€”

The Slider should use theme.palette.action.disabled.

Steps to Reproduce πŸ•Ή

Example showing that theme.palette.grey[400] is used: https://codesandbox.io/s/material-demo-qpzdk

image

Note: I've forced the color with !important for the screenshot above.

Actually, this demo shows another problem with the current style system - the custom disabled style is not applied, because the css specifity of the default disabled class is higher than the one of the custom class - is this wished? Should I create another issue for this problem?

image

Steps:

  1. Create a custom theme to see the difference between grey[400] and action.disabled
  2. set disabled to true

Context πŸ”¦

We edit some values of the palette, which leads to a difference between grey[400] and actions.disabled. All disabled inputs have the same color, except for the Slider component. image

@LorenzHenk Interesting. The specification has a section about the disabled state:

A disabled state communicates when a component or element isn’t interactive, and should be deemphasized in a UI. Disabled states are displayed at 38% opacity of the enabled state. Disabled states can also indicate they are inactive through color changes and reduced elevation.

https://material.io/design/interaction/states.html#disabled.

It seems that we can simplify things. What do you think of these changes?

elmeerr commented 4 years ago

@oliviertassinari how does the new changes regarding state anatomy impacts this issue? I might take a better look on those components

oliviertassinari commented 4 years ago

@elmeerr I don't understand what you mean? I have tried to take it into account :).

elmeerr commented 4 years ago

@oliviertassinari oh, sorry! I just wanna know if it's possible to use the new properties from theme (like you suggested in green) to update more components (if it's needed)

oliviertassinari commented 4 years ago

@elmeerr Right, I haven't looked into it. It's possible :)

LorenzHenk commented 4 years ago

@oliviertassinari I've also found the opacity hardcoded in ExpansionPanelSummary and ListItem:

Can I do anything to help? As a first issue?

oliviertassinari commented 4 years ago

@LorenzHenk Sorry for the delay. Do you want to work on the problem? I have updated #10870 to track all the progress on this epic (umbrella issue).

LorenzHenk commented 4 years ago

Sure!
