@CaiJimmy Sorry for the long time I neglected the merge conflict. Fixed now.

If you're not keen on merging this, please say, and I will close the PR and simply include it in my site layouts. Personally I use it a lot, and thought others may also appreciate it.

No need to apologize. I am the one who should apologize for leaving this so long without processing it.

Once I finish with my course I'll take a look at this ASAP.

Thanks for your patience and help 🙏

Thanks!

I've done some modifications (moving quote.scss into article.scss). This style is only used on the article page, so it makes more sense to have it there.

Sorry again for taking so long.

Thanks, all good!
