TextUI

TextUI component is meant to be used when text is interactive, such as a Button text or TextField labels. Compared to the Text component, TextUI is bolder and has a tighter line height.

Props

Component props
Name	Type	Default
`align`	`"start" \| "end" \| "center" \| "forceLeft" \| "forceRight"`	`"start"`
	`"start"` and `"end"` should be used for regular alignment since they flip with locale direction. `"forceLeft"` and `"forceRight"` should only be used in special cases where locale direction should be ignored, such as tabular or numeric text. See the alignment variant for more details.
`children`	`React.Node`	-
	The text content to be displayed.
`color`	`"default" \| "disabled" \| "subtle" \| "success" \| "error" \| "warning" \| "shopping" \| "link" \| "inverse" \| "recommendation" \| "light" \| "dark"`	`"default"`
	The color of the text content. See the colors variant for more details.
`dataTestId`	`string`	-
	Available for testing purposes, if needed. Consider better queries before using this prop.
`id`	`string`	-
	A unique identifier for the element.
`inline`	`boolean`	`false`
	Indicates how the text should flow with the surrounding content. See the block vs inline variant for more details.
`italic`	`boolean`	`false`
	Indicates if the text should be displayed in italic. See the styles variant for more details.
`lineClamp`	`number`	-
	Visually truncate the text to the specified number of lines. This also adds the `title` attribute if `children` is a string, which displays the full text on hover in most browsers. See the overflow and truncation variant for more details.
`overflow`	`"normal" \| "breakAll" \| "breakWord" \| "noWrap"`	`"breakWord"`
	Indicates how the text content should handle overflowing its container. See the overflow and truncation variant for more details.
`ref`	`HTMLDivElement`	-
	Ref that is forwarded to the underlying element. See the ref variant for more details.
`size`	`"lg" \| "md" \| "sm" \| "xs"`	`"md"`
	The sizes are based on our font-size design tokens. See the sizes variant for more details.
`title`	`string`	-
	This populates the `title` attribute of the element, which is visible on hover in most browsers. This is useful when truncating the text with `lineClamp` when `children` is a `React.Node`. See the Title variant for more details.

Localization

Be sure to localize all text strings. Note that localization can lengthen text by 20 to 30 percent.

Keep text simple and short to avoid truncation or line wrapping in UI controls like buttons when translating languages that require more characters.

import { useState } from 'react';
import { Box, ColorSchemeProvider, Flex, SelectList, TextUI } from 'gestalt';

export default function Example() {
  const [language, setLanguage] = useState('default');

  const content = Object.freeze({

Variants

Alignment

Use align to adjust the positioning of text within wrapper elements.

import { Divider, Flex, TextUI } from 'gestalt';

export default function Example() {
  return (
    <Flex
      alignItems="center"
      height="100%"
      justifyContent="center"
      width="100%"
    >
      <Flex direction="column" gap={{ column: 4, row: 0 }} width={200}>
        <TextUI align="start">Start (default)</TextUI>
        <Divider />
        <TextUI align="end">End</TextUI>
        <Divider />
        <TextUI align="center">Center</TextUI>
        <Divider />
        <TextUI align="forceLeft">Force left</TextUI>
        <Divider />
        <TextUI align="forceRight">Force right</TextUI>
      </Flex>
    </Flex>
  );
}

Block vs. inline

The TextUI component allows you to specify whether you want block or inline text.

import { Box, Flex, TextUI } from 'gestalt';

export default function Example() {
  return (
    <Flex
      alignItems="center"
      height="100%"
      justifyContent="center"
      width="100%"
    >
      <Flex alignItems="start" direction="column" gap={{ column: 4, row: 0 }}>
        <TextUI>Some content in a default block element. (default)</TextUI>
        <Box>
          <TextUI inline>Inline text with the inline prop.</TextUI>{' '}
          <TextUI inline>More inline text.</TextUI>
        </Box>
      </Flex>
    </Flex>
  );
}

Colors

You can specify which color you want for your text. Most colors change in dark mode, but light and dark are available when no switch is desired.

import { Box, Flex, TextUI } from 'gestalt';

export default function Example() {
  return (
    <Flex
      alignItems="center"
      height="100%"
      justifyContent="center"
      width="100%"
    >
      <Flex alignItems="start" direction="column" gap={{ column: 3, row: 0 }}>
        <TextUI color="default">Default</TextUI>
        <TextUI color="subtle">Subtle</TextUI>
        <Box color="inverse" padding={1}>
          <TextUI color="inverse">Inverse</TextUI>
        </Box>
        <TextUI color="disabled">Disabled</TextUI>
        <TextUI color="error">Error</TextUI>
        <TextUI color="success">Success</TextUI>
        <TextUI color="warning">Warning</TextUI>
        <TextUI color="recommendation">Recommendation</TextUI>
        <TextUI color="link">Link</TextUI>
        <TextUI color="shopping">Shopping</TextUI>
        <Box color="primary" padding={1}>
          <TextUI color="light">Light</TextUI>
        </Box>
        <Box color="infoWeak" padding={1}>
          <TextUI color="dark">Dark</TextUI>
        </Box>
      </Flex>
    </Flex>
  );
}

Sizes

You can apply size options to define the size of the text. These font sizes follow those available through our Design Tokens.

import { Flex, TextUI } from 'gestalt';

export default function Example() {
  return (
    <Flex
      alignItems="center"
      height="100%"
      justifyContent="center"
      width="100%"
    >
      <Flex alignItems="start" direction="column" gap={{ row: 2, column: 0 }}>
        <Flex alignItems="center" gap={{ row: 2, column: 0 }}>
          <TextUI inline size="xs">
            Size 100
          </TextUI>
          <span lang="ja">
            <TextUI inline size="xs">
              こんにちは
            </TextUI>
          </span>
        </Flex>

        <Flex alignItems="center" gap={{ row: 2, column: 0 }}>
          <TextUI inline size="sm">
            Size 200
          </TextUI>
          <span lang="ja">
            <TextUI inline size="sm">
              こんにちは
            </TextUI>
          </span>
        </Flex>

        <Flex alignItems="center" gap={{ row: 2, column: 0 }}>
          <TextUI inline size="md">
            Size 300 (default size)
          </TextUI>
          <span lang="ja">
            <TextUI inline size="md">
              こんにちは
            </TextUI>
          </span>
        </Flex>

        <Flex alignItems="center" gap={{ row: 2, column: 0 }}>
          <TextUI inline size="lg">
            Size 400
          </TextUI>
          <span lang="ja">
            <TextUI inline size="lg">
              こんにちは
            </TextUI>
          </span>
        </Flex>
      </Flex>
    </Flex>
  );
}

Overflow & truncation

Gestalt provides utility options to deal with text overflow.

import { Box, Flex, TextUI } from 'gestalt';

export default function Example() {
  return (
    <Flex height="100%" justifyContent="center" width="100%">
      <Flex direction="column" gap={{ column: 2, row: 0 }} width={200}>
        <TextUI>breakWord (default):</TextUI>
        <Box color="secondary" padding={2} rounding={2}>
          <TextUI>
            This is a long and Supercalifragilisticexpialidocious sentence.
            次の単語グレートブリテンおよび北アイルランド連合王国で本当に大きな言葉
          </TextUI>
        </Box>

        <TextUI>normal:</TextUI>
        <Box color="secondary" padding={2} rounding={2}>
          <TextUI overflow="normal">
            This is a long and Supercalifragilisticexpialidocious sentence.
            次の単語グレートブリテンおよび北アイルランド連合王国で本当に大きな言葉
          </TextUI>
        </Box>

        <TextUI>breakAll:</TextUI>
        <Box color="secondary" padding={2} rounding={2}>
          <TextUI overflow="breakAll">
            This is a long and Supercalifragilisticexpialidocious sentence.
            次の単語グレートブリテンおよび北アイルランド連合王国で本当に大きな言葉
          </TextUI>
        </Box>

        <TextUI>lineClamp:</TextUI>
        <Box color="secondary" padding={2} rounding={2}>
          <TextUI lineClamp={2}>
            This is a long and Supercalifragilisticexpialidocious sentence.
            次の単語グレートブリテンおよび北アイルランド連合王国で本当に大きな言葉
          </TextUI>
        </Box>
      </Flex>
    </Flex>
  );
}

Styles

TextUI is available in italic style.

import { Flex, TextUI } from 'gestalt';

export default function Example() {
  return (
    <Flex
      alignItems="center"
      height="100%"
      justifyContent="center"
      width="100%"
    >
      <Flex alignItems="start" direction="column" gap={2}>
        <TextUI>Default</TextUI>
        <TextUI italic>Italic</TextUI>
      </Flex>
    </Flex>
  );
}

Title

The title attribute on a <div> can be used to show the full text of a truncated string on hover. That attribute is populated automatically when the text is truncated using lineClamp, as long as children is a string.
If children is a React.Node (e.g. when using Link), use the title prop to manually set the title attribute.

import { Box, Flex, Link, TextUI } from 'gestalt';

export default function Example() {
  return (
    <Flex
      alignItems="center"
      height="100%"
      justifyContent="center"
      width="100%"
    >
      <Flex alignItems="start" direction="column" gap={2}>
        <Flex alignItems="center" direction="column" gap={2}>
          <TextUI>
            Hover over the examples below for a few seconds to see the title
            text:
          </TextUI>

          <Box borderStyle="sm" maxWidth={400} padding={1}>
            <Flex direction="column" gap={3}>
              <Flex direction="column" gap={1}>
                <TextUI italic>
                  This title attribute is automatically added because lineClamp
                  is used and children is a string.
                </TextUI>
                <TextUI lineClamp={1}>
                  This is a long and Supercalifragilisticexpialidocious
                  sentence.
                  次の単語グレートブリテンおよび北アイルランド連合王国で本当に大きな言葉
                </TextUI>
              </Flex>

              <Flex direction="column" gap={1}>
                <TextUI italic>
                  This example uses lineClamp but has no title attribute,
                  because children is a React.Node.
                </TextUI>
                <TextUI lineClamp={1}>
                  <Link href="#">
                    This is a long and Supercalifragilisticexpialidocious
                    sentence.
                    次の単語グレートブリテンおよび北アイルランド連合王国で本当に大きな言葉
                  </Link>
                </TextUI>
              </Flex>

              <Flex direction="column" gap={1}>
                <TextUI italic>
                  This example uses lineClamp and children is a React.Node, but
                  uses the title prop.
                </TextUI>
                <TextUI
                  lineClamp={1}
                  title="This is a long and Supercalifragilisticexpialidocious sentence. 次の単語グレートブリテンおよび北アイルランド連合王国で本当に大きな言葉"
                >
                  <Link href="#">
                    This is a long and Supercalifragilisticexpialidocious
                    sentence.
                    次の単語グレートブリテンおよび北アイルランド連合王国で本当に大きな言葉
                  </Link>
                </TextUI>
              </Flex>
            </Flex>
          </Box>
        </Flex>
      </Flex>
    </Flex>
  );
}

Refs

Don't use ref to manipulate the underlaying HTML div or span elements. Use ref to only read HTML attributes. For example, a valid use case can be detecting truncation. The example below illustrates a case where detecting truncation allows rendering links contained within Text.

import { useEffect, useRef, useState } from 'react';
import { Box, Flex, Label, Link, Switch, TextUI } from 'gestalt';

export default function Example() {
  const [showLongText, setShowLongText] = useState(false);
  const [applyTruncationDetection, setApplyTruncationDetection] =
    useState(false);

  const text =
    'Tag brand partners in your Idea Pins with the paid partnership tool.';

  const veryLongText =
    'Tag brand partners in your Idea Pins with the paid partnership tool. Just make an Idea Pin in the app, add the paid partnership label and tag your partner brand. Once they approve the request, their brand name will show up on your Idea Pin. Brands can also choose to promote your Idea Pins as ads, boosting your reach to even more people. When you use the paid partnership tool, you work directly with brands to define the payment terms and process. Pinterest will not be directly involved in payment.';

  const textRef = useRef(null);
  const [ellipsisActive, setEllipsisActive] = useState(false);

  const isEllipsisActive = (element) =>
    element.offsetHeight < element.scrollHeight ||
    element.offsetWidth < element.scrollWidth;

  useEffect(() => {
    const checkEllipsisActive = () => {
      if (textRef.current) {
        if (!ellipsisActive && isEllipsisActive(textRef.current)) {
          setEllipsisActive(true);
        } else if (ellipsisActive && !isEllipsisActive(textRef.current)) {
          setEllipsisActive(false);
        }
      }
    };
    checkEllipsisActive();
    window.addEventListener('resize', checkEllipsisActive);
    return () => {
      window.removeEventListener('resize', checkEllipsisActive);
    };
  });
