Recently, CSS has supported "logical" direction based properties for margin, padding, border, etc!

Previous to this, we were able to define properties based on physical directions like left, right, etc. This was a problem when different writing modes come into play, such as Arabic which is written from right to left, or traditional Chinese, Japanese, which are written from top to bottom.

👉 These new properties automatically adjust to the writing mode without the need for media queries.

"block" indicates main axis of writing mode (top to bottom for English)

"inline" indicates the cross axis of the writing mode (left to right for English)

You can combine this to create different properties for margin, padding, border, size and inset

👉 margin-block-end
👉 padding-inline
👉 border-inline-start
👉 inline-size
👉 block-size

✨ This also has the benefit that it provides shorthands like margin-inline which sets both left and right margin

🐸 F.I.R.S.T Principles: A Guide to Better Code Testing

Unit testing is a crucial aspect of modern software development, ensuring code reliability and maintainability. To maximize testing efficiency, developers should follow the F.I.R.S.T principles:

- Fast
- Isolated
- Repeatable
- Self-Validating
- Thorough/Timely

By adhering to these principles, teams can create robust test suites that enhance code quality while maintaining development speed. Let’s explore each principle with practical examples in React.

👨‍🚀 Revisiting CSS Multi-Column Layout

A library for creating drawn animations using SVG. Many different animations are available, as well as the ability to create your own script for drawing SVG in any way you like.

🤖 I watch bloggers and noticed that every other one of them advertises zapier – a platform for automation. They say everything is so simple there: connect nodes, get a zap and that's it – craft your own agents. But a subscription costs $20 to make slightly complex zaps.

Then I decided to review open source with similar functionality. And I found automatisch. The service is rolled out with Docker and is ultra-simple. The approach of zapier is one to one, only poorer in functionality.
