😶‍🌫️ 10 Backend Terms Every Frontend Developer Should Know

When a backend dev gives their update in the daily standup meeting, most frontend devs are clueless about the work they're doing. They use a lot of jargons that sound gibberish to us frontend devs. But not anymore!

🎆 Relatively New Things You Should Know about HTML Heading Into 2025

Not all of this is like absolutely brand spanking new just-dropped-in-2024 stuff. Some of it is, but generally it’s relatively new stuff that’s all pretty great. I’m pointing things out that I think are really worth knowing about. It’s possible you haven’t kept up too much with HTML developments as it tends to, rightfully, move a lot slower than CSS or JavaScript.

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
