Changes the line length in Obsidian Notes. Tested with Obsidian v1.0.0

Note: For this to work the "readable line length" property in settings has to be enabled in settings (as expected).

700px is the default width, just adjust the number below.

Pixels px (or percentage %) are possible units that enable a width independent from the number of characters (good when adjusting the zoom level or font size). For fixed amount of characters use rem, e.g. 70rem

Hi, just found out this snippet. I think now you need to add !important for it to take effect, but otherwise still works great in the newest version.
Aka,

body {
	--file-line-width: 750px !important;
}

what if you are just trying to change this setting on specific pages I attempted adding a cssclass to the page a

halo, bro. Have you had it fixed? specific pages works, but not affect other pages

In case helpful to anyone... I've been using variations of the above snippet for some time. After Obsidian 1.0, I had a hard time getting a custom width to consistently work. Played around and came up with the following simple solution to replace all of the above. -- limited testing

/* Custom Line Width */
body {
	--line-width: 60rem !important;
	--tab-stacked-pane-width: 850px; /* Optional pane width increase */
}
/* Custom Line Width - fixes custom html elements except dataview plugin which this negatively impacts */
.markdown-source-view.mod-cm6.is-readable-line-width .cm-embed-block > div:not(.block-language-dataview) {
	max-width: 100%;
}

Thanks! This worked for me.
