;;; Commentary:
;; This file provides some additional configuration for HTML based
;; modes. To use it, simply add:
;;
;; (require 'smartparens-html)
;;
;; into your configuration. You can use this in conjunction with the
;; default config or your own configuration.
;; This file provides these interactive functions:
;; `sp-html-next-tag' - Recommended binding: C-c C-f
;; `sp-html-previous-tag' - Recommended binding: C-c C-b
;;
;; (These two bindings are used for navigation by tags forward or
;; backward, but `sp-forward-sexp' already does that.)
;; If you have good ideas about what should be added please file an
;; issue on the github tracker.
;; For more info, see github readme at
;; https://github.com/Fuco1/smartparens
