Custom handling of specific YAML keys

So, I have some YAML keys I’d like to specifically target just like it is possible for Aliases and Tags. I only have basic knowledge about CSS and HTML, and none as to how Obsidian sets these CSS classes.

See my reply here for a little more details on why this is hard:

Reduced frontmatter in Reading view

This should be doable with some CSS. If you turn back on the showing of the frontmatter, it shows all frontmatter, but you can hide stuff you don’t want. Here is an image showing source text, reading view and corresponding DOM elements related to the frontmatter display. [image] What we can see here is that tags and aliases have the CSS classes of frontmatter-section and respectively mod-aliases and mod-tags, and that the other lines just have the frontmatter-section. So if we generally hid…

To summarise, the tags and aliases have dedicated classes which make them targetable by CSS. The other don’t, and could to some extent be targetted by applying stuff like nth-child(). This however requires a very strict usage of order in the frontmatter, which is hard to do consistently.

I’ve seen some custom classes plugins, but I don’t think they’re applicable to the frontmatter. So I reckon you’d have to turn to some plugin, which could parse the frontmatter, and then add classes similar to the tags and aliases classes. I’ve not seen this plugin so far.

Another option could be to move stuff out of your frontmatter into inline fields, which has is pros and cons. One of the pros is that the fields themselves are then tagged with more classes than they’re in the frontmatter. But I’m not sure if that is a viable/wanted solution for you.
