padding and border-radius available?

I was looking for the same features but didn’t find it. So i edited its css style using custom css plugin and here’s the css

.crayon-syntax, .crayon-main{
  padding : 10px;
  border-radius : 5px;
}

It works well, you can see the result here https://laravel.enjinir.com/2016/02/09/laravel-5-2/

Hope it helps ??
