Customizing

CSS Variables

You can adjust the appearance of Seia with CSS variables.

For example, to apply the Material 3 color scheme:

:root {
  --seia-color-bg: var(--md-sys-color-surface-variant);
  --seia-color-text: var(--md-sys-color-on-surface-variant);
  --seia-color-primary: var(--md-sys-color-primary);
}

Style Element

You can inject styles into the Shadow DOM via the css attribute.

<s-e-i-a css=".h-cite{padding:1rem};"></s-e-i-a>

Presets

Seia has prepared a number of presets.

Dark Mode

Add simple dark mode support for the default color scheme.

It is not enabled by default since custom color schemes are encouraged.

<s-e-i-a
  css="@import url('https://cdn.jsdelivr.net/npm/seia/dist/styles/material.css');"
></s-e-i-a>

Emoji Fonts

Seia uses text rather than icons, so importing Emoji fonts and setting the font-family should work. for example:

/* Noto Colr Emoji Glyf */
@import url('https://fonts.googleapis.com/css2?family=Noto+Colr+Emoji+Glyf&display=swap');
