字體排印

styled 套件預設使用系統字體堆疊：

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

這會在各個平台上使用作業系統的原生字體進行渲染（macOS 上的 San Francisco，Windows 上的 Segoe UI，Android 上的 Roboto）。系統字體提供了良好的多語言支援，因為作業系統會自動處理中日韓、阿拉伯文和其他腳本的備用字體。

若要覆寫，請在任何祖先元素上設定 --rdrp-font-family — 它會串聯至選擇器中。

CSS 變數行內樣式

透過在包覆元素上使用 style 屬性來覆寫字體：

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>
  );
}

字體家族

透過在包覆元素上設定 --rdrp-font-family 來切換字體家族：

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>
  );
}

使用網頁字體 (Noto Sans)

對於需要一致跨平台渲染或國際化 (i18n) 的專案，可以載入像 Noto Sans 這樣的網頁字體並覆寫該變數：

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

// 1. 在您的 HTML 或 CSS 中載入 Noto Sans：
//    <link href="https://fonts.googleapis.com/css2?family=Noto+Sans:wght@400;500;600;700&display=swap" rel="stylesheet">

// 2. 覆寫字體變數：
<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>
  );

網頁字體展示

比較不同的網頁字體，看看字體排印如何顯著改變選擇器的外觀。以下所有字體都支援多語言渲染（拉丁文、中日韓、韓文）。

⚠️ 僅供示範

以下字體是從 Google Fonts CDN 載入以供示範。此函式庫不包含任何網頁字體 — 您需要在自己的專案中載入它們。

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>
  );

字體大小與字重

透過覆寫大小和字重變數來微調字體排印的密度：

變數	預設值	描述
`--rdrp-font-size-xs`	`11px`	最小的文字
`--rdrp-font-size-sm`	`12px`	星期標籤
`--rdrp-font-size-base`	`13px`	日期儲存格、按鈕
`--rdrp-font-size-md`	`14px`	觸發器、時間項目
`--rdrp-font-size-lg`	`15px`	月份標題
`--rdrp-font-weight-normal`	`400`	基本字重
`--rdrp-font-weight-medium`	`500`	中等強調
`--rdrp-font-weight-semibold`	`600`	已選日期、標題
`--rdrp-font-weight-bold`	`700`	今日指示器
