  description

  CssHub syncs your CSSBattle submissions to a GitHub repository you choose.
  
  How it works:
  • Play challenges on cssbattle.dev (or www.cssbattle.dev)
  • Sign in with GitHub and pick a repo and branch
  • Sync passes as commits with optional preview images
  
  Built for CSSBattle and GitHub only—the extension runs on CSSBattle play pages and talks to GitHub (plus a small OAuth helper for secure web sign-in). Your GitHub token stays in session storage on your device. Settings and a short activity log stay in local extension storage. CssHub does not run analytics or store your battles on CssHub servers.

  CssHub saves your CSSBattle solutions to GitHub automatically.
  
  Stop copy-pasting submissions or losing track of old solutions. CssHub turns your CSSBattle Battles and Daily Targets into a clean GitHub history you can browse, share, and keep as part of your portfolio.
  
  How it works:
  • Play Battles or Daily Targets on cssbattle.dev or www.cssbattle.dev
  • Sign in with GitHub
  • Choose a repository and branch
  • Sync passing submissions as commits with preview images
