# css direction rtl ignored inside nested flex container

## TL;DR

Fixes RTL layouts where a nested flex container ignores the direction. Set direction on the nested container or use logical properties throughout. Use when inner flex items lay out left-to-right inside an RTL page. Not for text bidi issues.

## The error

```text
Nested flex toolbar lays out left-to-right although the page has dir=rtl.
```

## Fix it

### Step 1: Inspect the computed direction

```bash
node -e "console.log('check the nested container computed direction in devtools')"
```

Expected: You see the nested container computes to ltr.

### Step 2: Set direction or logical properties on the nested container

```bash
node -e "console.log('add direction rtl or replace physical margins with logical ones')"
```

Expected: The nested container lays out right-to-left.

### Step 3: Verify across breakpoints

```bash
node -e "console.log('resize and confirm the toolbar mirrors at every width')"
```

Expected: The layout mirrors correctly everywhere.

## When to use this

- A nested flex container ignores the page RTL direction
- Inner components were built LTR-first

## When NOT to use this

- Text runs in the wrong order, that is a bidi problem
- The whole page is LTR, set dir=rtl on the root

## Tool and version compatibility

- All modern browsers
- Flexbox with physical vs logical properties

## Variant phrasings

### only the toolbar is wrong

The toolbar component sets its own direction. Override it at the component level.

### wrong only in one browser

That browser needs the direction set explicitly; inheritance differs.

## Why it happens

Direction inherits, but any explicit direction or physical property on a nested container overrides it. Components built for LTR often hardcode physical margins and direction, which win over the inherited RTL.

## Edge cases

- margin-left never mirrors; margin-inline-start does
- Third-party components may need an RTL theme variant
- Screenshots in LTR only will never catch this
