Resolved: Remove “::before” — CSS

Question:

Currently heading of my blogpost on blogger looks like this. So I wanted to remove this “-” like looking element from my blog, which is a ::before. I tried this advice here and used a little ingenuity to added a CSS like so:

div.post-body-container::before{
    content: none;
}

And some other variations of the same. Where am I going wrong here?
This is my blog btw if it is needed on which I’m using Soho Neon theme.

Answer:

Try using content: '' instead.

div.post-body-container::before {
  content: '';
}

If you have better answer, please add a comment about this, thank you!
