Actually, if that was pasted into Additional CSS or the style.css file itself, it would have no effect at all. Apart form the CSS section complaining about it with red errors.
Exactly, many red errors indicating that saving the code may break the site. That's what I said.
But it's the same as Mar's. (Except for the CSS
Riiiiiight. Except Mar said to paste the code into functions.php and you said to paste it into CSS. Not only did you say to add it as custom CSS, you gave explicit instructions on exactly how to navigate to the custom CSS section. It's not even remotely the same, and it wasn't a matter of typing "CSS" instead of "functions.php". LOL
You just need to practise recognising the obvious difference between CSS code and PHP code
I am not a coder - I don't claim to be, but then I'm not the one giving bad coding advice and pretending it was user error when it doesn't work. Frankly, it wasn't even your advice, it was Mar's code that you copied and then amended with explicit instruction on how to insert it in the wrong place. So while you're doling out advice on personal improvement, maybe you could brush up on a few things yourself, starting with humility...and spelling. I believe you meant 'practice' and 'recognizing'. Just saying.
I won't be responding to you any further, despite the snide comments that are sure to follow. With that in mind, here's some unsolicited advice back at ya' - tame the egotistical, know-it-all act in the forums, especially in light of this glaring "blooper", to use your term. Forums should be a safe place to learn and ask dumb questions without judgement, and to get answers from people who either KNOW the answer, or have enough sense to be quiet and let someone who does know weigh in. The forums are not here for the benefit of your ego, to regurgitate (poorly) reworded Moderator suggestions, or as a platform to showboat about how many websites you built with other people's coding in the form of plugins.
BTW, my solution works beautifully on Flatsome; it's my theme also. If you don't want your functions.php overwritten with every update, consider giving it a try.
