// Bootstrap Mid-Small - col-ms-* - the missing grid set for Bootstrap3.

// This is a hack to fill the gap between 480 and 767 pixels - a missing range
// in the bootstrap responsive grid structure.  Use these classes to style pages
// on cellphones when they transition from portrait to landscape.

// Contains:
//   Columns, Offsets, Pushes, Pulls for the Mid-Small layout
//   Visibility classes for the Mid-Small layout
//   Redefined visibility classes for the Extra Small layout

This gist shows how to download a vcard with mime-type

It's easy to provide a simple link to download a vcard. The problem is that normal devices doesn't recognize the downloaded vcard and will most often just render them in the browser as plain text.

This gist is an example of how you can download the vcard with proper mime-type, which allows the device to recognize it as a vcard.

Prerequisites

This example assumes that you have a model Contact with a connected vcard. This example was built using a simple carrierwave uploader to upload the vcard to amazon s3.

What is this?

It's a way to better handle page specific css and javascript files. It gives you full control of which files are included and compiled where. This is a way to easily minimize the file request while still keeping out unnecessary stuff from the files, without you as a developer need to edit environment files.

Why not controller specific files?

guides.rubyonrails.org mentions a way to easily handle controller specific stylesheets and javascript files. Like:

javascript_include_tag params[:controller]

Sometimes that's not enough or it will break because of some gem you have installed, and that's when this method comes in handy.
