How can the 2 gaps, indicated by the white arrows (sorry, I did not know how to give them a different color) be closed?

In other words, at the top the purple box should border the pink status bar (Mac), and on the right it should border the edge of the screen.

The border around UI elements can be tweaked in Style Settings (User Interface → Window Adjustments → Window Gap (px)). How come you don’t have the sidebar on the right or the Titlebar in Obsidian? The gap is set to be there to help with having an edge for resizing the workspace windows. It’s setup to go around the entire note window because of how windows sit next to each other when you open more notes to the sides or above/below.

@Damikiller37 thanks, that worked. I set the gap to its minimum, which is 1 instead of zero, I cannot reach zero, so there is still a tiny gap. Why?

Regarding the sidebar on the right, it is hidden because I only use it occasionally. I have bound a hotkey (⌃ ⌥ R) to it.

As for the titlebar, I have it hidden with the Hider plug-in.

Hi @Damikiller37 , thanks for this great theme. Prism is my favorite (Pine flavor), and I’m now using it as my default theme (along with Style Plugin).
However, I have a problem. Perhaps I’m slightly color blind, but I have difficulty seeing and finding the cursor. Are there any ways I can emphasize the cursor? Thanks in advance, and I look forward to future improvements!


Fat cursor:

.cm-cursorLayer .cm-cursor {
  border-left-width: 5px;

As I mentioned the reason why the gap needs to exist is because that’s where the resize handles for the Workspace windows are. If it was 0 you would be stuck with the window size that is set when you open multiple notes and now way to change it. I’ve tried to tackle this issue some time ago and it’s proven to be very tricky with how you can place notes any way you like. Also I’ve not really accounted for people removing the Titlebar or the sidebars.

As @Klaas mentioned you can temporarily use his code as a snippet. I’ll see what I can do with it to make it more prominent (Color? Thickness? Faster animation?).

OK, thanks for the explanation, I understand. 1 as a minimum makes sense now.

It might be something to consider, seeing Hider has been installed 35,000 times.

@Damikiller37 I checked the Style Settings but could not find it: how can I hide/eliminate the relationship lines in bullet point lists?

@Klaas I haven’t done any customisation for the Relationship lines in Bullet point lists. They have been natively added fairly recently in Obsidian. I could look into adding a toggle to remove them if that’s something that is brought up more frequently. For now you should be able to remove them with this snippet:

.markdown-source-view.mod-cm6 .cm-indent::before, li > ul::before, li > ol::before {
    display: none;

P.S. A lot of existing Prism customisation focused on the UI and Plugins so any Editor specific improvements / feature requests are welcome. I’ve been careful not to create a kitchen sink of features on the mentality of “because I can” and rather add things that people actually want and will use. I also try to avoid adding things which are specific to a user or two, because in most cases those can be solved by a snippet.

@Damikiller37 I checked it out in the native Settings, and indeed, the feature is there is called Show indentation guides. So I just toggled it off.

I am surprised they added that to the native settings, but at least it is togglable.

As for your feature policy, that seems to be a sensible one, and you have done a good job with the theme.


Hi there! I love the theme so far, but I’m having an issue with changing the graph line colors. I’m just using the snippet:

.graph-view.color-line {
color: #a3a0fc;

And it works on default theme and other themes, but something in Prism seems to override it and make it gray. How would I go about changing the line color?

@enzorocksmith try adding !important to the 2nd line:

color: #a3a0fc !important;

Worked, thanks for the fix :slight_smile:

I’ve added this as a feature alongside all the other Graph customisations in Style Settings. It will be available in v2.1.0 when it’s released.

:iphone:Mobile Showcase

:coffee: Support Prism Development

Unfortunately the theme still doesn’t work for iOS. Below is a screenshot of my homepage on mobile. As you can see, nothing is showing up.

:gem: Prism v2.1.1

Quick Fixes

  • Fixed workspace rendering issues on iOS; Edit views should now display correctly.
  • Other small fixes related to iOS and mobile in general.

If you encounter other issues with mobile (iOS specifically) let me know :slightly_smiling_face:

In dark mode I am using the Pine theme (I love it), but selecting text needs a higher contrast, while the global search box could also do with a background color change.
