Change the "before" element above the heading

Hi to everyone !

If this topic already exist I’m sorry but after some research there is no result for my request.

There is my question :

Is it possible to change h1(&h2).content-title::before content ? For exemple, change dots by an icon.

In fact, I tried to see what svf file are pointed on this element but it seems that it’s just CSS.

Thank you

Sorry, there’s no simple code snippet for this, it would require a custom implementation. If customizations beyond the available features are required for your site, please consider hiring someone for custom work https://fvrr.co/32e7LvY
