10-82: 📐 Maintainability & Code Quality | 🟠 Major | 🏗️ Heavy liftContent does not match the stated topic: This is a CSS guide with no CSS content.
The title promises "CSS modern features in 2026" but the entire body contains generic placeholder text with zero actual CSS. The code examples are TypeScript/React components, not CSS. A post with this title should cover concrete modern CSS features (e.g., container queries,
:has(), cascade layers,@property,color-mix(),anchor()positioning, etc.) with actual CSS code blocks.This appears to be an uncustomized template. Before merging, replace all placeholder content with substantive CSS-focused material that matches the title's promise.

- Around line 12-16: Fix the grammar and capitalization in the blog post copy:
in the opening paragraph, change the subject-verb agreement in the sentence
starting with “CSS modern features continues…” to use the plural verb form, and
in the “Why CSS modern features Matters” heading/paragraph, normalize “css
modern features” to “CSS modern features” for consistent casing. Update the
affected text in the markdown content only, keeping the existing structure and
wording otherwise unchanged.
- Around line 73-76: The conclusion sentence has a subject-verb agreement error
in the blog post text. Update the wording in the conclusion block to either
treat “CSS modern features” as plural with matching verb/adjective, or rewrite
it to use “Understanding CSS modern features” as the singular subject; locate
this in the conclusion content of the MDX article and adjust the sentence for
grammatical consistency.
- Around line 1-8: Replace the draft body in the blog post with polished
CSS-focused content and correct the broken image reference. Update the post
content so it uses real CSS modern-feature examples (not TypeScript/React
snippets), fixes the generic wording and casing/grammar issues, and aligns with
the title using the main article body. Also update the frontmatter image field
in the same post so it points to an existing asset, using the image path that
matches the post’s available images.

Replace the placeholder body and fix the broken image reference
- The post still reads like draft copy: the text is generic, includes grammar/casing issues, and uses TypeScript/React snippets instead of CSS examples.
image: './images/post-image.png'points to a missing asset, so the published post will render a broken image.

Fix grammar and casing inconsistencies.
- Line 12: "CSS modern features continues to evolve" → "CSS modern features continue to evolve" (subject-verb agreement).
- Line 16: "css modern features" → "CSS modern features" (consistent capitalization).

Suggestion: This post is marked as published, but it is stored outside the only configured content collection path (blog/**/*.mdx), so it will never be indexed or rendered on blog pages. Move the file under content/blog/... (or update the collection pattern) so publishing actually works. [api mismatch]
Severity Level: Major ⚠️
- ❌ New 2026 CSS post never appears on /blog listing.
- ⚠️ Authors think published flag works but content hidden.Steps of Reproduction ✅
1. Inspect `velite.config.ts:4-8,23-25`, where the `posts` collection is defined with
`pattern: 'blog/**/*.mdx'` and `root: 'content'`, meaning only files under
`content/blog/...` ending in `.mdx` are indexed.
2. Inspect the blog listing page implementation in `app/blog/page.tsx:8-19`, which uses
the `posts` collection, filters `post.published`, and renders the blog index at route
`/blog`.
3. Inspect the new post file
`content/blog-post-2026-07-01/css-modern-features-in-2026-a-practical-guide.mdx:1-8`,
noting that its frontmatter sets `published: true` at line 6 but the file is located under
`content/blog-post-2026-07-01/` rather than `content/blog/`.
4. Run the app (e.g., `npm run dev`) and visit `/blog`; observe that the new “CSS modern
features in 2026” article does not appear in the list even though it is marked `published:
true`, because its path does not match the `blog/**/*.mdx` pattern and it is never
included in the `posts` collection consumed by `app/blog/page.tsx`.
