Banner

The Banner component is usually used to identify the status or notification of the full page. It is usually resident and requires the user to close it initiatively.

Demos

import { Banner } from '@fibrous/semi-ui-solid';

Basic Usage

Code
import { createSignal, Show } from 'solid-js';
import { Banner, Button, Layout } from '@fibrous/semi-ui-solid';

const commonStyle = {
    height: '64px',
    'line-height': '64px',
    background: 'var(--semi-color-fill-0)',
};

export default function BannerDemo() {
    const [visible, setVisible] = createSignal(false);
    const changeVisible = () => {
        setVisible(!visible());
    };

    return (
        <>
            <Layout class="components-layout-demo banner-basic">
                <Layout.Header style={commonStyle}>Header</Layout.Header>
                <Show when={visible()}>
                    <Banner onClose={changeVisible} description="Semi D2C 现已支持 Figma DevMode, 安装插件,随时查阅图层对应的前端代码" />
                </Show>
                <Layout.Content style={{ height: '300px', 'line-height': '300px' }}>Content</Layout.Content>
                <Layout.Footer style={commonStyle}>Footer</Layout.Footer>
            </Layout>
            <Button
                onClick={changeVisible}
                style={{
                    display: 'block',
                    width: '120px',
                    margin: '0 auto',
                }}
            >
                {visible() ? 'Hide Banner' : 'Show Banner'}
            </Button>
        </>
    );
}

Types

The type prop supports one of: default(default),danger,warning, success.




Code
import { Banner } from '@fibrous/semi-ui-solid';

export default function BannerDemo() {
    return (
        <>
            <Banner type="info" description="Semi D2C 现已支持 Figma DevMode, 安装插件,随时查阅图层对应的前端代码" />
            <br />
            <Banner type="warning" description="当前使用 Figma UI Kit 为旧版,可能无法支持完整的 Design to code 能力" />
            <br />
            <Banner type="danger" description="当前使用 API 已过期,请尽快升级" />
            <br />
            <Banner type="success" description="Semi DSM, Make Semi Design to Any Design" />
        </>
    );
}

Use in Container

You could set fullMode={false} to use style for non-fullscreen mode. Also, use bordered for bordered style. icon={null} and closeIcon={null} hide the icon and the close button.




Code
import { For, Show } from 'solid-js';
import { Banner, Typography } from '@fibrous/semi-ui-solid';

const { Text } = Typography;

const types = ['info', 'warning', 'danger', 'success'] as const;

const titleStyle = {
    'font-weight': '600',
    'font-size': '14px',
    'line-height': '20px',
};

export default function BannerDemo() {
    return (
        <div style={{ width: '640px' }} class="components-banner-demo">
            <For each={types}>
                {(type, index) => (
                    <>
                        <Show when={index() > 0}>
                            <br />
                        </Show>
                        <Banner
                            fullMode={false}
                            type={type}
                            bordered
                            icon={null}
                            closeIcon={null}
                            title={<div style={titleStyle}>不知道 AppKey?</div>}
                            description={
                                <div>

    );

    return (
        <div style={{ width: '500px', padding: '20px', border: '1px solid var(--semi-color-border)' }}>
            <Banner fullMode={false} title="Title" type="warning" bordered description="Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat">
                <div class="semi-modal-footer">
                    <button class="semi-button semi-button-tertiary semi-button-light" type="button">
                        No, thanks.
                    </button>
                    <button class="semi-button semi-button-warning" type="button">
                        Sounds great!
                    </button>
                </div>
            </Banner>
            <br />

API Reference

class, style, ref and native attributes and events (such as aria-* and onClick) land on the root element (role="alert"). The root's role is fixed and cannot be overridden. The closed state lives inside the component; unmount and mount again to show it again.

Accessibility

ARIA

  • The component has a role of 'alert'.
  • The close button's aria-label comes from the current locale ('Close' in English, '关闭' in Simplified Chinese).

Keyboard and Focus

  • The close button of the Banner can be focused with the Tab key. After the button is focused, hit the Enter key or the Space key to close the banner.

Content Guidelines

  • Full screen Banner
    • Try to keep the content displayed completely on one line
    • Use correct punctuation, commas within sentences and periods between sentences
  • Non-fullscreen Banner
    • title
      • Instructions in condensed language
      • Try to avoid using commas, periods and other punctuation marks in the title, and support the use of question marks at the end when there are and only interrogative sentences
    • text
      • On the premise of complete information transmission, try to compress the text to 1-2 sentences
      • A detailed description or explanation of the title, rather than a repetition of the title
      • Use correct punctuation, commas within sentences and periods between sentences

Design Tokens

These are the component's internal Sass variables and cannot be overridden. To customize styles, override the --semi-* CSS variables (see the Design Token page) or write unlayered CSS rules.
