# `MishkaBlog.Plugins.ContentComponents`
[🔗](https://github.com/mishka-group/mishka_blog/blob/v0.0.1/lib/mishka_blog/plugins/content_components.ex#L5)

Tells a site's stylesheet which components its posts draw, which icons they name and which
classes they write, through the `runtime:compile:content_components` hook
`MishkaCmsCore.Runtime.Compilers.TailwindCompiler.content_components/1` fires while it builds a
site's stylesheet: the names the site's published posts list in `content_components`, the icon
classes they list in `content_icons` and the classes they list in `content_classes`, which
`MishkaBlog.Resources.Changes.ContentFacts` stores when a post is written. A template that draws a
post's body — the kit's `blog-post-detail` — then reaches those components and no others
(`MishkaCmsCore.Runtime.Compilers.CssClosure`), the stylesheet carries a rule for each icon, and
it is built with each class.

Read as the system, as the sitemap reads them (`MishkaBlog.Plugins.SitemapUrls`): a post locked to
some readers draws its components, icons and classes for them, so it counts. Only the posts that
name a component, an icon or a class are read, and only those columns. Registered in
`MishkaBlog.Application`.
