Theming Context

Theming

To customize the application, a custom theme files that serve as overrides to the existing tokens can be provided. An example implementation of the main project CSS file would look like:

@import '@rolemodel/optics';

@import 'stylesheets/theme/my_app_theme';

Note how the custom theme is imported after the main Optics styles, ensuring that any token overrides take precedence.

A custom theme can change any tokens, including colors, radius, fonts, and even redefine the luminosity and semantic scales.

@import url('https://fonts.googleapis.com/css2?family=Coming+Soon&display=swap');
@import url('https://fonts.googleapis.com/css2?family=Grandstander:ital,wght@0,100;0,200;0,300;0,400;0,500;0,600;0,700;0,800;0,900;1,100;1,200;1,300;1,400;1,500;1,600;1,700;1,800;1,900&display=swap');

:root {
  /* Colors */
  --op-color-primary-h: my-new-value;
  --op-color-primary-s: my-new-value;
  --op-color-primary-l: my-new-value;

  /* Color Scale */
  --op-color-primary-plus-two: light-dark(
    hsl(var(--op-color-primary-h) var(--op-color-primary-s) 64%),
    hsl(var(--op-color-primary-h) var(--op-color-primary-s) 32%)
  );

  /* Fonts */
  --op-font-family: 'Coming Soon', sans-serif;
}

@media (prefers-color-scheme: dark) {
  :root:not([data-theme-mode='light']) {
    --op-font-family: 'Grandstander', sans-serif;
  }
}

:root[data-theme-mode='dark'] {
  --op-font-family: 'Grandstander', sans-serif;
}

Color Scale Overriding

If you need to override the provided color scales, you should redefine all the variants of that color to ensure consistency across the application. For example, if you are overriding the primary color, you should redefine all its variants like so:

:root {
  --op-color-primary-h: 164;
  --op-color-primary-s: 100%;
  --op-color-primary-l: 50%;

  /* Main Scale */
  --op-color-primary-plus-two: light-dark(
    hsl(var(--op-color-primary-h) var(--op-color-primary-s) 64%),
    hsl(var(--op-color-primary-h) var(--op-color-primary-s) 32%)
  );
  --op-color-primary-plus-one: light-dark(
    hsl(var(--op-color-primary-h) var(--op-color-primary-s) 45%),
    hsl(var(--op-color-primary-h) var(--op-color-primary-s) 35%)
  );

  /* On Scale */
  --op-color-primary-on-plus-two: light-dark(
    hsl(var(--op-color-primary-h) var(--op-color-primary-s) 16%),
    hsl(var(--op-color-primary-h) var(--op-color-primary-s) 80%)
  );
  --op-color-primary-on-plus-two-alt: light-dark(
    hsl(var(--op-color-primary-h) var(--op-color-primary-s) 6%),
    hsl(var(--op-color-primary-h) var(--op-color-primary-s) 92%)
  );
  --op-color-primary-on-plus-one: light-dark(
    hsl(var(--op-color-primary-h) var(--op-color-primary-s) 100%),
    hsl(var(--op-color-primary-h) var(--op-color-primary-s) 80%)
  );
  --op-color-primary-on-plus-one-alt: light-dark(
    hsl(var(--op-color-primary-h) var(--op-color-primary-s) 95%),
    hsl(var(--op-color-primary-h) var(--op-color-primary-s) 98%)
  );
}
