@sheryl, have you tried to open an issue on BracketHighlighter to get some help? I am fairly repsonsive.
BracketHighlighter may require a restart of Sublime after installation to get working.
If you are hoping for JSX tag name highlighting via BracketHighlighter, that doesn’t exist currently. I’m not a web programmer, and though I’ve had many requests to add support for tag highlighting in JSX, none of the requesters have yet wanted to volunteer time to bring me up to speed on JSX format in regards to tags. Due to the fact that it acts more as a template language in regards to HTML tags, the dynamic nature may be too difficult to do in the traditional way that HTML tag highlighting is performed in BracketHighlighter, but I don’t know as everyone has bailed as soon as I start asking questions.
So while BracketHighlighter does not provide JSX tag highlighting, it does provide highlighting for a number of other brackets and bracket like objects.
