How to Get the Output of Ansible Ad-Hoc Command in JSON, CSV or Other Format

What are the most common CSS practices?

The best thing to usually start with is a CSS reset. The one I usually use is http://meyerweb.com/eric/tools/css/reset/

The goal of a reset stylesheet is to reduce browser inconsistencies in things like default line heights, margins and font sizes of headings, and so on. The general reasoning behind this was discussed in a May 2007 post, if you're interested. Reset styles quite often appear in CSS frameworks, and the original "meyerweb reset" found its way into Blueprint, among others.

The reset styles given here are intentionally very generic. There isn't any default color or background set for the body element, for example. I don't particularly recommend that you just use this in its unaltered state in your own projects. It should be tweaked, edited, extended, and otherwise tuned to match your specific reset baseline. Fill in your preferred colors for the page, links, and so on.

In other words, this is a starting point, not a self-contained black box of no-touchiness.

Compare two files with Ansible

Why not using stat to compare the two files?
Just a simple example:

- name: Get cksum of my First file
  stat:
    path : "/poc/files/{{ inventory_hostname }}.result"
  register: myfirstfile

- name: Current SHA1
  set_fact:
    mf1sha1: "{{ myfirstfile.stat.checksum }}"

- name: Get cksum of my Second File (If needed you can jump this)
  stat:
    path : "/poc/files/transport.results"
  register: mysecondfile

- name: Current SHA1
  set_fact:
    mf2sha1: "{{ mysecondfile.stat.checksum }}"

- name: Compilation Changed
  debug:
    msg: "File Compare"
  failed_when:  mf2sha1 != mf1sha1
