Web Extra

lang.web adds frontend HTML, CSS, Tailwind, and Emmet support with Prettier formatting. It complements lang.typescript rather than replacing it — Tailwind and Emmet also attach to JSX/TSX buffers when they are present.

Enable it

-- ~/.config/blak/lua/blak/user.lua
return {
  extras = {
    enabled = {
      "lang.web",
    },
  },
}

Or enable it interactively:

:BlakExtras enable lang.web

What it adds

Surface	Contribution
Treesitter	`html`, `css`, `scss`
Mason	`prettier`, `prettierd`
LSP	`html`, `cssls`, `tailwindcss`, `emmet_language_server`
Formatting	`prettierd` (fallback `prettier`) for `html`, `css`, `scss`, `less`

Language servers install automatically through Mason: html/cssls map to vscode-langservers-extracted, tailwindcss to tailwindcss-language-server, and emmet_language_server to emmet-language-server. Only the Prettier formatters need an explicit Mason entry.

Notes

The Tailwind server attaches only when it detects a Tailwind config in the project, so there is no cost on non-Tailwind codebases.
Emmet expansion and Tailwind completion both attach to HTML, CSS, and JSX/TSX buffers; they are complementary, not conflicting.

Install and verify

:BlakToolsInstall
:BlakTreesitterInstall
:BlakDoctor

Open an .html or .css file and check :LspInfo for html, cssls, and emmet_language_server. Open a file in a Tailwind project to see tailwindcss attach.
