Hi, I've got a couple of suggestions that will make your post easier for people to read 😊.

If you surround a block of code with three backticks, before and after your code becomes a code block, like this.

.shadow-inset-all {
  box-shadow: inset 0 0 5px #333;
}

Just doing this makes code more readable. It's also worth including a little text describing what you're doing and why.

---

Demo are also great, you can use jsfiddle to make demo for free and embed it like so.

{% jsfiddle https://jsfiddle.net/link2twenty/h4rkfoq5/ result html css %}

---

And finally make sure your tags match your content, for instance in this one you've included react but your post doesn't touch on that.

I hope you find this helpful.
