Also, it's not really necessary, or even a good idea, to combine all JS files into one big JS minimize file for a number of reasons.

It is not good to "over optimize" and little really great comes of it, in my view.

Most sites like this are changing often and there is always a lot of Javascript code to write, modify, change and debug. Creating "mothers of all minimized Javascript files" make things "a nightmare" and it is better to smartly combine them, and that cannot be done by tool because we need to know that we are developing, where the issues are, what is changing, and what is static.

But anyway, I'm not focused on it and it is not on the site development critical path to worry about minimizing more JS and CSS. I have a lot more important functional code to write for the next month or so.

Cheers and Thanks!

I usually combine and minify them dynamically based on filetime, no issue even if you modify or change code it will work.

- create md5 hash of file to be combined and minified based on filetime.
- check filename with above generated hash exists.
- if exists just readfile otherwise combine and minify them and then serve to client.

One more probably you missed, "Toggle Forum Collapse" button plus symbol not changing when its expanded.

CSS frameworks

I have been reading up on CSS frameworks, to see if it could be useful for an intranet that I am helping to build, but the true purpose does not become clear to me. What circumstances would the deployment of a CSS framework be useful in? What does a CSS framework do that a CMS template cannot do?

Plack::Middleware::File::Sass(3pm)			User Contributed Perl Documentation			Plack::Middleware::File::Sass(3pm)

NAME

       Plack::Middleware::File::Sass - Sass and SCSS support for all Plack frameworks

SYNOPSIS

	 use Plack::App::File;
	 use Plack::Builder;

	 builder {
	     mount "/stylesheets" => builder {
		 enable "File::Sass";
		 Plack::App::File->new(root => "./stylesheets");
	     };
	 };

	 # Or with Middleware::Static
	 enable "File::Sass", syntax => "scss";
	 enable "Static", path => qr/.css$/, root => "./static";

DESCRIPTION

       Plack::Middleware::File::Sass is a Plack middleware component that works with Plack::App::File or Plack::Middleware::Static to compile Sass
       <http://sass-lang.com/> templates into CSS stylesheet in every request.

       When a request comes in for .css file, this middleware changes the internal path to .sass or .scss, depending on the configuration, in the
       same directory. If the Sass template is found, a new CSS stylesheet is built on memory and served to the browsers.  Otherwise, it falls
       back to the original .css file in the directory.

       This middleware should be very handy for the development. While Sass to CSS rendering is reasonably fast, for the production environment
       you might want to precompile Sass templates to CSS files on disk and serves them with a real web server like nginx or lighttpd.

SASS BACKENDS

       If you have the sass gem version higher than 3 installed and have the "sass" executable available in your PATH, this module automatically
       uses the command to convert Sass or SCSS into CSS. If the command is not available and you have Text::Sass perl module available, it will
       be used. Otherwise you'll get an exception during the initialization of this middleware component.

OPTIONS

       syntax
	   Defines which syntax to use. Valid values are sass and scss. Defaults to sass.
