Can't break lines on Wordpress / Never programmed before, be patient : I'm totally a newbie in programming. In fact, I never programmed before. I'm creating a WordPress and everytime that I insert a code that was supposed to work in breaking a line doesn't and it turns off my WordPress.

If you could, ***please***, would you care to teach me, step by step, how to break a line from the WordPress Title?

I tried a lot, I read a lot, I even asked on Reddit but no one couldn't help me.
