Code review

I like the red
I like the sidebar
The sidebar has nice icons
The dark theme support is baller
It was easy to register and it made me make a secure password
I like that it's using CSS grid. The layout mode of the future.
The markup is semantic with descriptive tags like section and main, etc. This will make it nicely crawlable by search engines like google. This will also make it nicer for people without eye balls who use the internet with screen readers. That's pretty cool and considerate!
I rate it: very awesome blog/10
My only suggestion is that there's a severe lack of the marquee tag. The one that makes the text scroll from right to left like the text at the bottom of news broadcasts. More marquee would be a nice touch.
