Content splitting at the end and Headings not starting with majuscule

[Faneks]

Hello, happy holidays and have a great day everyone!

So I have this newly made blog, it's in a different language but it shouldn't matter.

I posted my first article and found out that there's some problems. It looks like a mess.

My problems lay in the fact that words will split at the end of the line and that Headings do not start with an uppercase letter. Overall formatting looks pretty bad. From my research, I understand the theme is doing this. I tried to tweak it myself but my coding skills are super limited.

Unfortunately I can't post links, but here's a photo, hope it's okay.

Can anyone please help me with some custom CSS? If there is another way, great, but I doubt it.

Thanks for your time to anyone reading this!
