Wrapper (is--wrapper)

is--wrapper is a class that collectively controls the width of its direct child content.

CSS

.is--wrapper {
  // 子要素の制御
  --contentSize: var(--sz--m, 100%);
  > * {
    inline-size: 100%; // l--stack 等の縦並び配下で自然幅要素のガタつきを防ぐ
    max-inline-size: min(100%, var(--contentSize)); // min ないとimg要素等がはみ出す
    margin-inline: auto;
  }
}

// Memo: .-contentSize:s / m / l / xl は contentSize Prop の auto-generated 出力（src/scss/_prop-config.scss 経由）から自動的に props 層に出力される。

Direct children receive inline-size: 100%, so even elements whose natural width is below --contentSize (short paragraphs, <table>, etc.) always stretch to the parent width. This keeps widths consistent under l--stack and other vertical layouts and prevents jagged edges.

Using with Lism Components

It can be applied via the isWrapper prop on any component.

A dedicated <Wrapper> component is also available as an alias for <Lism isWrapper>.

Import

import { Wrapper } from 'lism-css/react';

import { Wrapper } from 'lism-css/astro';

Props

// ①
<Flow isWrapper="s" isContainer>...</Flow>

// ②
<Wrapper contentSize="s" layout="flow" isContainer>...</Wrapper>

Usage

Example

<Wrapper layout="flow" p="20">
  <p>Content</p>
  <p>Content</p>
  <p>...</p>
</Wrapper>

<div class="l--flow is--wrapper -p:20">
  <p>Content</p>
  <p>Content</p>
  <p>...</p>
</div>

<Wrapper contentSize="s" layout="flow" p="20">
  <p>Content</p>
  <p>Content</p>
  <p>...</p>
</Wrapper>

<div class="l--flow is--wrapper -contentSize:s -p:20">
  <p>Content</p>
  <p>Content</p>
  <p>...</p>
</div>

Setting a custom container size

To use a value other than s, m, l, or xl, pass any value to isWrapper and it will be output as the --contentSize CSS variable.

<Lism isWrapper="20rem" p="20">
  <div>Contents...</div>
  <div>Contents...</div>
</Lism>

<div class="is--wrapper -p:20" style="--contentSize: 20rem">
  <div>Contents...</div>
  <div>Contents...</div>
</div>
