In the Obsidian Dev Console, I can increase the font size of the left and right panels and the status bar. However, it isn’t permanent. So, I have to change it daily. I am using the Ebulliantworks theme. I have tried to find the specific properties in the CSS code, but I’ve been unsuccessful. I did manage to change the font size in the calendar, but due to eye issues, I need to find a way to permanently change the font size of the sidebars and status bar.
i noticed that i forgot that and edited my post a few minutes ago to include that.
You could also split the selectors if you don’t want the same font-size for all three.
