Theme Stress Test
This post exists to stress-test the theme’s typography, spacing, wrapping, and “rich” blocks.
It intentionally includes long words (pneumonoultramicroscopicsilicovolcanoconiosis), long URLs (https://example.com/this/is/a/very/long/path/with_a_really_really_really_long_segment_that_should_wrap_nicely), and long inline code like THIS_IS_A_SINGLE_TOKEN_THAT_SHOULD_WRAP_OR_OVERFLOW_GRACEFULLY_DEPENDING_ON_CONTEXT_0123456789.
You should also try switching theme (system/light/dark) and font (sans/serif) while viewing this post.
Headings, spacing, and inline elements
A paragraph with italics, bold, bold italics, ~~strikethrough~~, and a link: Example link. Also test a “bare” URL: https://example.com.
Inline code should use the mono font: --base-size, --measure, --underline-thickness.
Keyboard keys should look like keys: press Cmd+K, then Esc.
Superscripts/subscripts: E = mc2, H2O.
H3: A subsection heading
This is a normal paragraph under an H3. Here’s a second sentence with a longUnbrokenIdentifierThatShouldStillBreakSomewhereEvenWithoutHyphenationBecauseOverflowWrapIsEnabled.
H4: Smaller heading
H5: Even smaller
H6: Smallest (muted)
Lists
Unordered list
- One item
- Another item with inline code:
const x = 1 - Nested list:
- Sub-item A
- Sub-item B
- Sub-sub-item with a long token:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
- Sub-sub-item with a long token:
Ordered list
- First step
- Second step
- Third step
- Sub-step 3.1
- Sub-step 3.2
Mixed content in lists
- A paragraph in a list item can be multi-line and still keep the correct spacing.
It should remain readable, not cramped, and should wrap nicely.
- Another item
Blockquotes
This is a blockquote. It should have a left rule and slightly muted text.
It can span multiple paragraphs.
- And it can contain lists
- Which should inherit the quote styling
Callouts
Below are raw HTML callouts using the exact classes the theme styles.
Code blocks
Plain fenced code (no language)
This is a plain code fence.
It should still get the theme’s pre/code styling (wrap, padding, border, radius).
Language-tagged code fence (for Pygments / codehilite setups)
from dataclasses import dataclass
@dataclass
class Thing:
name: str
value: int
def demo(xs: list[int]) -> dict[str, int]:
# Long line to test wrapping in code blocks:
very_long = "0123456789" * 18 + "_THIS_LINE_IS_INTENTIONALLY_LONG_TO_FORCE_WRAPPING_AND_TEST_READABILITY"
return {str(i): i*i for i in xs}
// JavaScript sample: long string + unicode + template literals
const title = "Theme Stress Test — Δ, café, naïve";
const longLine = "x".repeat(220) + "_WRAP_ME_PLEASE";
console.log(`${title}\n${longLine}`);
/* CSS sample: token-like content */
:root {
--bg: #18181b;
--text: #f8fafc;
--measure: 55ch;
--underline-thickness: 2px;
}
Indented code block (classic Markdown)
Indented code block.
It should look consistent with fenced code.
Tables
Markdown table (if your Markdown config enables tables)
| Token | Value | Notes |
|---|---:|---|
| --measure | 55ch | Readable line length |
| --base-size | 17px | Body text size |
| --p-space | 0.86em | Paragraph spacing |
| --underline-thickness | 2px | Always-underlined links |
Wide HTML table wrapped in the theme’s .table-wrap
| Column A | Column B | Column C | Column D | Column E | Column F |
|---|---|---|---|---|---|
| Short | Numbers | inline_code() |
Long text that should wrap inside the cell without breaking layout | https://example.com/some/really/long/url/that/should/wrap | ✅ |
| Row 2 | 1234567890 | --surface-2 |
More wrapping text. More wrapping text. More wrapping text. | pneumonoultramicroscopicsilicovolcanoconiosis | 🧪 |
| Row 3 | - | {"json":"ok"} |
Try switching to light theme and confirming zebra striping remains subtle. | Mixed: Café naïve coöperate soufflé | 🌗 |
Figures (no featured image, but still exercising figure styles)
<figure> with an inline SVG using .hero-graphic for the theme’s border/radius.
Details / disclosure widgets
Click to expand a <details> block
This should render with a border, rounded corners, and a subtle surface. The <summary> line should look clickable.
- Nested list item
- Another list item
Open by default
This one starts open, to test spacing when expanded.
Duplicate headings + unicode (ID generation stress)
Duplicate heading
Some text.
Duplicate heading
Some text again — the theme’s JS should assign a unique id for this duplicate.
Café naïve coöperate soufflé
Accents should be handled consistently in generated anchor ids.
Footnotes (theme-styled)
Footnote reference example1 and a second one2.
Footnotes
- This is footnote 1. It should be slightly smaller and muted, but still readable. ↩︎
- This is footnote 2. Include a link inside the footnote: example.com. ↩︎
Final edge cases
- A very long “word” that is not code: antidisestablishmentarianismantidisestablishmentarianismantidisestablishmentarianism
- A very long inline code token:
SOME_RIDICULOUSLY_LONG_CONSTANT_NAME_THAT_SHOULD_NOT_DESTROY_LAYOUT_ABCDEFGHIJKLMNOPQRSTUVWXYZ_0123456789 - A line with many em dashes — like this — to see spacing and wrapping.
- Mixed punctuation: “quotes”, ‘quotes’, ellipsis… and arrows → ↩︎ ✓
That’s it. If anything looks off, it’s probably either: 1) a Markdown extension mismatch (tables/footnotes), or 2) an HTML element that needs a small theme rule.
