Add a vertical 80-character reference line in the plain-text editor

ASSUMPTION.

  • This is only particularly useful if you have a monospace font set for the editor: Tools > Options > Appearance > Editor font family.
  • Also, if you set the Editor monospace font family to something different than the above, the line will be drawn inaccurately for preformatted text blocks (the browser calculates the size based not on the Joplin applied font - weird). You can remove .cm-jn-code-block-background from the CSS below if you still want a reference line but want to remove it from the preformatted blocks.
  • The units used here are ch units. 1ch = the width of the current font's 0 character.

A simple example - drawing a vertical red line

This first is a simple example of how the linear-gradient function works. We are asking the browser to paint a background from left to right: transparent to the 80th character (80ch), red from 80th to 80.25 (80ch 80.25ch), and then immediately go transparent from character 80.25 (80.25ch) to the right side of the block.

userchrome.css
Joplin version tested on: 2.8.8

.CodeMirror-code,
.cm-jn-code-block-background {
    /* a thin vertical line at the 80-character mark - red */
    background-image: linear-gradient(to right, transparent 80ch, red 80ch 80.25ch, transparent 80.25ch) !important;
}

Drawing a theme-friendly line (which is really two lines) . . .

Now red is a rather stark color. I want something nice and unobtrusive. But unobtrusive is not friendly if you are changing themes. The solution: use two colors and draw two vertical lines next to each other. One color will be visible with light themes. The other, during dark themes. Magic! And to add unobtrusive nuance, we pick stark colors that contrast with each end of the theme spectrum and then fade them out with function rgba's alpha setting (it controls the opacity of the applied color.

For this I pick two nearly gray colors that also have some blue. Anthracite is very dark. It has a complementary version that I am calling anthracite-light. each will be faded to 10%. You will see the light one in the dark themes. And you will see the dark one in the light themes.

userchrome.css
Joplin version tested on: 2.8.8

.CodeMirror-code,
.cm-jn-code-block-background {
    --rgb-anthracite-light: 169,181,212; /* set to 10% for dark themes */
    --rgb-anthracite: 57,61,71; /* set to 10% for light themes */
    background-image: linear-gradient(to right, transparent 80ch, rgba(var(--rgb-anthracite-light),10%) 80ch 80.25ch, rgba(var(--rgb-anthracite),10%) 80.25ch 80.5ch, transparent 80.5ch) !important;
}

Note: If you have two different monospace fonts set

Hopefully, this is useful for you. Cheers!

Remove the "New to-do" button to free up space above the note list (v2.10)

userchrome.css
Joplin version tested on: 2.10.18

Joplin desktop 2.10.x introduces a new style for the "New note" and "New to-do" buttons which change based on the width of the note list. Sometimes this can make the search bar rather small. Personally I do not use to-do notes so the below css will remove the "New To-do" button and the space it occupies.

4

button.new-todo-button {
    /* removes the "New To-do" button (v2.10.6+) */
    display: none;
}
div.new-note-todo-buttons {
     /* removes the the space for the "New To-do" button (v2.10.6+) */
    grid-template-columns: 1fr 0;
    gap: 0px;
}

The "New note" button and search bar still adjust according to the width of the note list.

The sort order button has also been switched off using the option in Joplin settings.

"Fake" Mixed Case Tags

userchrome.css
Joplin version tested on: 2.13.15

This will make the tag list and the tags on the note display a capital letter for the first letter of each word in the tag. Note that this is a display modification only. Within Joplin the actual tag data itself is unchanged.

span.tag-label,
div.tag-list button {
    text-transform: capitalize;
}
