# Show tabs in code blocks 4 columns wide

Branch `feature/tab-size` · version 0.5.1

## What changed

- **`tab-size: 4` on code blocks.** Browsers show a tab as 8 columns by default. gofmt indents Go with tabs, so quoted Go code ran past the edge of its box two levels in. Code blocks now show tabs 4 columns wide.
- **Test:** the stylesheet test checks the rule is there.
- **Version:** 0.5.1.

## Notes

- Posts can now quote Go exactly as gofmt writes it, with tabs, instead of re-indenting with spaces. The pinned-posts post was re-indented with spaces before this fix and looks the same either way.
- The stylesheet's content hash changes, so browsers fetch the new file on their next visit without a hard refresh (v0.2.1).

## Testing

- All tests pass with the race detector (`go test -race ./...`).
- Rendered the same tab-indented Go snippet with the old and new stylesheet:

| Before (8 columns) | After (4 columns) |
