Dear Pinegrow users,
When we receive an email from you through our support channel, we assume that you have already thoroughly reviewed our documentation and tutorials (note: using the search bar can be a great help!), our Youtube Channel, our community forum and our Slack channel.
You should find excellent documentation on these topics via the following links:
HTML and CSS
Bootstrap 3.3.x Framework
Foundation 6.X Framework
However, we take good note of all the questions/use case we receive and depending on the frequency of similar requests, we maybe publish specific tutorials on our documentation site in the near future.
