Best way to apply css to a set of notebooks/notes

Support
1

I’m using Joplin to write notes in English (LTR) and Farsi (RTL). Currently, I add the following snippet at the beginning of my notes in Farsi to make it render properly:

<style>
@import url('https://fonts.googleapis.com/css?family=Lateef&display=swap');
body {
    direction: rtl;
    <!--font-family: 'Lateef', cursive;-->
}
</style>

I was wondering if there’s a simpler more convinient way of doing this in Joplin. I was thinking of maybe based on tags? For example, apply this style on notes with tag farsi.

No, the only way is to add it to your userstyle.css file, but in that case it will be applied to all notes.

Hmm... Just thinking out loud.
I saw that HTML in the note does not mean it becomes HTML in actual DOM.
Maybe there's a hack for it to become part of the DOM?

Theoretically, user could wrap specific note text in HTML

with a certain class and then use CSS descendant selectors to conditionally style the child nodes of this div.

I'm not a Farsi speaker, but I've just copied a text sample to Joplin and it looks good to me.

@tessus is correct. There is no simple way to do that (per-notebook CSS) yet. But you can make it easier for yourself via …

Instead of this in each note:

… add this to the top of your userstyle.css stylings configuration: Options > General > Appearance > Show Advanced Settings > Custom stylesheet for rendered Markdown. (@import statements need to be at the top.):

@import url('https://fonts.googleapis.com/css?family=Lateef&display=swap');

… and then add this to the bottom of your userstyle.css stylings configuration:

.myfarsi, .myfarsi p {
    direction: rtl;
    font-family: 'Lateef', cursive;
}

Finally restart Joplin for it to see that change. Then add this to the top of each Farsi-language note:

<div class="myfarsi">

This here is your note.
Blah blah blah, so on and so forth.

You don't really even have to terminate that bit of HTML with a </div> at the end of the note. The renderer sees the end of the file and treats it as if it were terminated.

And, personally, I would also install the Templates plugin and use that to keep a template that looks just like that above also ready at a click every time to wanted to write in Farsi.

That should just work and reduce the clutter for you. Note, I didn't test for typos in my CSS here, but I think I got it right. Play with it and see if that works for you.

This pattern should also allow you to have an predominantly English language note (no <div …> at the top) interspersed with Farsi.

This is my note. Blah Blah Blah. <span class="myfarsi">And this some Farsi Text</span> And this here is more English.

Again, not tested, and I don't know how well that works in the same paragraph, but you get my drift. It could be:

This is my note. Blah Blah Blah.

<div class="myfarsi">

And this a paragraph written in Farsi

</div>

And here the note continues in English.

You could also add a .myenglish class in userstyle.css so you can do the reverse (a bit of LTR English in a Farsi note).

Have fun! Hope this helps.
