This is a fork of original gist https://gist.github.com/nrollr/3f57fc15ded7dddddcc4e82fe137b58e, with slight changes on pointing to 5.7 version branch, instead of 8 (latest default of MySQL in Hombrew).

Install MySQL 5.7 on macOS

This procedure explains how to install MySQL using Homebrew on macOS (Sierra 10.12 and up)

Install Homebrew

• Installing Homebrew is effortless, open Terminal and enter :
  $ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
• Note: Homebrew will download and install Command Line Tools for Xcode 8.0 as part of the installation process.

/*
This .scss loop will create "margin helpers" and "padding helpers" for use in your web projects.
It will generate several classes such as:

.m-r-10 which gives margin-right 10 pixels.
.m-r-15 gives MARGIN to the RIGHT 15 pixels.
.m-t-15 gives MARGIN to the TOP 15 pixels and so on.

.p-b-5 gives PADDING to the BOTTOM of 5 pixels
.p-l-40 gives PADDING to the LEFT of 40 pixels
