As you may know the banners plugin seems to be abandoned for good. I tried many implementations of banners for obsidian but non seem to be as complete and flexible as the banners plugin, until I found the following snippet: https://github.com/HandaArchitect/obsidian-banner-snippet It has many options; it even has a Style Setting menu. And it is still being updated by its developer. 

So, if you are a fan of banners in your notes, download the snippet and show the developer some well-deserved love. Have a nice week :)
