Happy New Year 2022
1. Overview
First of, happy new year!
2. Statistics
This year I decided to present the stats a little differently and made the infographic below.
The infographic image was made in "Canva" (an online diagram/image editing app). You can view the source image here.
3. Updates
-
Started the upgrade from CSS to SCSS (using hugo-extended).
-
Started migrating from Markdown to AsciiDoc (using AsciiDoctor support provided by Hugo).
-
Settled on a colour scheme and program (Affinity Designer) for drawing diagrams.
-
Purchased both Affinity Designer (for making diagrams) and Affinity Photo (for touching up photos), and both have been well worth their one-of purchase price (take that, Adobe and your subscription model).
-
Upgraded the main menu from hover style interface to an accordion style interface, making it more user friendly for people using touchscreen devices.
-
Upgraded the base layout of every page to use Bootstrap responsive columns, rather than my own custom CSS to achieve the same level of responsiveness.
