Typography

The styled package uses a system font stack by default:

--rdrp-font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, sans-serif;

This renders with the OS native font on each platform (San Francisco on macOS, Segoe UI on Windows, Roboto on Android). System fonts provide good multi-language support since the OS handles CJK, Arabic, and other script fallbacks automatically.

To override, set --rdrp-font-family on any ancestor element — it cascades into the picker.

CSS Variable Inline Style

Override the font via the style attribute on a wrapper element:

import { useState } from "react";
import { DatePicker } from "react-date-range-picker-styled";
import "react-date-range-picker-styled/rdrp-styles.css";

function CSSCustomFont() {
  const [value, setValue] = useState<Date | null>(null);

  return (
    <div
      style={{
        ["--rdrp-font-family" as string]: '"Georgia", "Times New Roman", serif',
      }}
    >
      <DatePicker value={value} onChange={setValue} />
    </div>
  );
}

Font Family

Switch between font families by setting --rdrp-font-family on a wrapper:

import { useState } from "react";
import { DatePicker } from "react-date-range-picker-styled";
import "react-date-range-picker-styled/rdrp-styles.css";

const fonts = {
  System: {},
  Serif: { "--rdrp-font-family": '"Georgia", "Times New Roman", serif' },
  Mono: { "--rdrp-font-family": '"Menlo", "Courier New", monospace' },
};

type FontName = keyof typeof fonts;

function CompoundCustomFont() {
  const [value, setValue] = useState<Date | null>(null);
  const [font, setFont] = useState<FontName>("System");

  return (
    <div>
      <div style={{ display: "flex", gap: 6, marginBottom: 12 }}>
        {(Object.keys(fonts) as FontName[]).map((name) => (
          <button
            key={name}
            onClick={() => setFont(name)}
            style={{
              padding: "6px 14px",
              border: `1px solid ${font === name ? "#3b82f6" : "#d1d5db"}`,
              borderRadius: 6,
              background: font === name ? "#eff6ff" : "#fff",
              cursor: "pointer",
              fontSize: 13,
            }}
          >
            {name}
          </button>
        ))}
      </div>
      <div style={fonts[font] as React.CSSProperties}>
        <DatePicker value={value} onChange={setValue} inline />
      </div>
    </div>
  );
}

Using Web Fonts (Noto Sans)

For consistent cross-platform rendering or i18n projects, load a web font like Noto Sans and override the variable:

import { DatePicker } from "react-date-range-picker-styled";
import "react-date-range-picker-styled/rdrp-styles.css";

// 1. Load Noto Sans in your HTML or CSS:
//    <link href="https://fonts.googleapis.com/css2?family=Noto+Sans:wght@400;500;600;700&display=swap" rel="stylesheet">

// 2. Override the font variable:
<div style={{ "--rdrp-font-family": '"Noto Sans", sans-serif' } as React.CSSProperties}>
  <DatePicker value={value} onChange={setValue} inline />
</div>;

import { useState, useEffect } from "react";
import { DatePicker } from "react-date-range-picker-styled";
import "react-date-range-picker-styled/rdrp-styles.css";

function CompoundNotoSans() {
  const [value, setValue] = useState<Date | null>(null);

  useEffect(() => {
    // Load Noto Sans from Google Fonts (for demo purposes only)
    if (!document.getElementById("noto-sans-font")) {
      const link = document.createElement("link");
      link.id = "noto-sans-font";
      link.rel = "stylesheet";
      link.href =
        "https://fonts.googleapis.com/css2?family=Noto+Sans:wght@400;500;600;700&display=swap";
      document.head.appendChild(link);
    }
  }, []);

  return (
    <div style={{ "--rdrp-font-family": '"Noto Sans", sans-serif' } as React.CSSProperties}>
      <DatePicker value={value} onChange={setValue} inline />
    </div>
  );
}

Web Font Gallery

Compare different web fonts to see how dramatically typography changes the picker’s look. All fonts below support multi-language rendering (Latin, CJK, Korean).

⚠️ Demo only

The fonts below are loaded from Google Fonts CDN for demonstration purposes. This library does not bundle any web fonts — you need to load them in your own project.

import { useState, useEffect } from "react";
import { DatePicker } from "react-date-range-picker-styled";
import "react-date-range-picker-styled/rdrp-styles.css";

const WEB_FONTS = [
  { name: "Noto Sans", family: '"Noto Sans", sans-serif' },
  { name: "Noto Serif", family: '"Noto Serif", serif' },
  { name: "IBM Plex Sans", family: '"IBM Plex Sans", sans-serif' },
  { name: "Roboto Slab", family: '"Roboto Slab", serif' },
];

const FONT_URL =
  "https://fonts.googleapis.com/css2?family=IBM+Plex+Sans:wght@400;500;600;700&family=Noto+Sans:wght@400;500;600;700&family=Noto+Serif:wght@400;500;600;700&family=Roboto+Slab:wght@400;500;600;700&display=swap";

function CompoundWebFonts() {
  const [value, setValue] = useState<Date | null>(null);
  const [active, setActive] = useState(0);

  useEffect(() => {
    if (!document.getElementById("web-fonts-link")) {
      const link = document.createElement("link");
      link.id = "web-fonts-link";
      link.rel = "stylesheet";
      link.href = FONT_URL;
      document.head.appendChild(link);
    }
  }, []);

  return (
    <div>
      <div style={{ display: "flex", gap: 6, marginBottom: 12, flexWrap: "wrap" }}>
        {WEB_FONTS.map((f, i) => (
          <button
            key={f.name}
            onClick={() => setActive(i)}
            style={{
              padding: "6px 14px",
              border: `1px solid ${active === i ? "#3b82f6" : "#d1d5db"}`,
              borderRadius: 6,
              background: active === i ? "#eff6ff" : "#fff",
              color: active === i ? "#3b82f6" : "#374151",
              cursor: "pointer",
              fontSize: 13,
              fontFamily: f.family,
            }}
          >
            {f.name}
          </button>
        ))}
      </div>
      <div style={{ "--rdrp-font-family": WEB_FONTS[active].family } as React.CSSProperties}>
        <DatePicker value={value} onChange={setValue} inline />
      </div>
    </div>
