Double brackets in internal links

Is there a way to view double square brackets around internal links in preview mode ?

.internal-link::before{
content: “[[”;
color: var(–brackets-color);
}

.internal-link::after{
content: “]]”;
color: var(–brackets-color);
}

i put it in css folder ?

I put it in css folder , but no things happened

Make a new css file and put it in your “Snippets” folder. Then, turn the snippet on in settings. You can open the “Snippets” folder if you go to “Appearance” in settings and press the folder icon on the same line as “CSS Snippets.”

i tried , but no thing happened too …

Try changing the curly quotes to straight quotes?

The quotes seem correct in the source but Discourse somehow ruined it.
