In my themes/variables.scss I have two color themes (dark and light):
/* LIGHT COLOR THEMES
========================================= */
/*$colors: (
primary: #ffffff,
secondary: #fafafa,
danger: #f53d3d,
light: #1b1e28,
sliderColor: #fff,
colorIcon: #CCCBDA,
colorIconText: #7F7E96,
category: #fff,
listBackgroundColor: #ffffff,
backgroundColor: #fafafa,
toobarBackground: #ffffff,
toobarButton: #AAB2B7,
toobarText: #FFFFFF
);*/
/* DARK COLOR THEMES
========================================= */
$colors: (
primary: #282C39,
secondary: #1b1e28,
danger: #f53d3d,
sliderColor: #fff,
light: #fff,
colorIcon: #7F7E96,
colorIconText: #7F7E96,
category: #fff,
listBackgroundColor: #1B1E28,
backgroundColor: #282C39,
toobarBackground: #1B1E28,
toobarButton: #D8D8D8,
toobarText: #FFFFFF
);
Right now I can only put one theme in my app. If I want to change the theme, I have to comment the one variable out and the other I have to remove the comments.
How can I using these two themes, change the theme dynamically in the app in typescript?
In every tutorial I see these --ion-color-primary but I do not have these --ion-color prepending
You can do this in a couple of ways. The main idea is that define your colors class. you can have for example -
// light theme
:root {
// define your light colors here
}
// dark theme
:root body.dark {
// define you dark colors here
}
So by default, the light theme will be applied, as the <body> of you application does not hold any class. Now to apply dark theme you just simply add class dark to the <body> of you application. For example, you can have a service for that which simply selects the body and adds the class to it. And remove it to go back to light theme.
import { Injectable } from '#angular/core';
#Injectable({
providedIn: 'root'
})
export class ThemeService {
constructor() { }
applyDark() {
document.querySelector('body').classList.add('dark');
}
removeDark() {
document.querySelector('body').classList.remove('dark');
}
}
By the way, I see you are using you own color variable. I've just given the example using the default ionic variables (from src/theme/variables.scss)

I want to change Chip's background color when it's variants value is 'filled' because the default light gray doesn't feel satisfactory.
I read MUI docs and Chip API but it's too complicated for me..
You could make use of Chip's exported CSS classes
import Chip, { chipClasses } from "#mui/material/Chip";
import { styled } from "#mui/material/styles";
// ..
const CustomChip = styled(Chip)({
[`&.${chipClasses.filled}`]: {
backgroundColor: "red"
}
});

If I import a colour from material ui as follows:
import blue from '#material-ui/core/colors/blue';
I can use it as follows for the colors in the palette that do not include "A":
const theme = createMuiTheme({
palette: {
primary: { main: blue[100] },
How can I access the colors that are prefixed with "A"?
For example, #82b1ff is in blue - with reference A100. When I try:
primary: { main: blue[A100] },
I get an error saying A100 is not defined.
What do I need to be able to use the colors that are defined with an A?
I have been searching the web for a while, but I could not understand how to apply the default dark theme that is shown in the site of Material-ui, where you can toggle between the light and dark theme.
They say those are default ones, but how do I use them?
Thanks!
You can use them by creating a Theme like this:
import { MuiThemeProvider, createMuiTheme } from '#material-ui/core/styles';
const THEME = createMuiTheme({
palette: {
type: 'dark',
},
});
class YourComponent extends Component {
render() {
return (
<MuiThemeProvider theme={THEME}>
... your other components
</MuiThemeProvider>
)
}
}
export default YourComponent;
The toggle can be done with a button like this example.
In an Ionic v4 app, I have a label component where I want to apply the secondary-shade color, but it doesn't work if I want to apply it directly from the color attribute.
This is how I am applying the color:
<ion-label color="secondary-shade">Secondary shade Label</ion-label>
Applying the color from the CSS is working though:
ion-label {
--color: var(--ion-color-secondary-shade);
}
To give secondary-shade color using color attribute directly, you need to define secondary-shade color inside variables.scss.
Go to src/theme/variables.scss and add your secondary-shade color to $colors as below.
$colors: (
primary: #488aff,
secondary: #32db64,
danger: #f53d3d,
light: #f4f4f4,
dark: #222,
secondary-shade: #f53dc7
);
Now you can use it as you preferred.
<ion-label color="secondary-shade">Secondary shade Label</ion-label>
Simply need to use withStyles some how to edit the default color from the primary/error color to simply just use black. But since the update from 0.19.0 to beta 1 this doesn't seem possible now.
The error message (the one under the text input) is using the object under theme.palette.error (see source) to choose which color to use.
That same palette color is used for the text field label too.
If you want to change both at the same time the right approach would be to use a custom theme that rewrites the theme.palette.error to something else.
import { createMuiTheme, createPalette } from 'material-ui/styles';
import grey from 'material-ui/colors/grey';
const theme = createMuiTheme({
palette: createPalette({
error: grey
})
});
If you want to change just the FormHelperText color then you could customize it in theme by using the overrides parameter.
const theme = createMuiTheme({
overrides: {
MuiFormHelperText: {
error: {
color: 'black'
}
}
}
});
To change the Label of the TextField in the current version (v1.2.1)
You have to set the the color like this:
const theme = createMuiTheme({
palette: {
text: {
secundary: 'black'
}
}
}
});
for error the path is palette.error.main
the easiest way to find the right variables is to look directly into the code
