Welp, I had the same problem before! I just did some research, and I found some incredible posts that helped me a lot!

Sorry for answering a bit too late, I went back to sleep really early yesterday hahaha

"Steemit posting Tutorial" (by Hive account@beanz)

"How to make your Steemit posts look beautiful: A quick guide" (by Hive account@vitkolesnik)

"❓Answering Common Questions: How do people align things? How do I get those fancy designs between paragraphs? 🎭" (by Hive account@sykochica)

But still, it requires some practice and also experimenting a bit! :)

And the text fonts, I just copy and paste whichever text I want from this website! :)

I also use symbols from this website!

And I often use this logo maker to make cool titles! Like in this post I wrote recently! :)

Also, this guide is pretty useful if you are just starting, like me! :)

I hope this helped you! :)
