I used Dreamweaver CC to set up a responsive html page using the provided templates.
Then I built the article by hand.
Then I used Chrome and Safari to create/edit new classes within each media query until the article looked good on two phone sizes and one tablet size.
I then duplicated the entire folder and set up a second article. It was a similar yet different enough article that I had to make some tweaks to some of the classes. Each was zipped independently with their own CSS, images, and fonts.
