{{[[roam/css]]}} component block
?disablecss=true to the URL (before the #) — all roam/css is disabled until the next refresh. You can also disable all js and css from the "Roam Depot" tab in settings
setTimeout(() => { debugger }, 3000) in the DevTools console, then hover the element — the page freezes in the debugger so you can inspect it
rm- (a few older structural ones use roam-)
bp3- classes come from Blueprint, the UI library Roam uses — you can target them too, but prefer rm- classes when both match
document.querySelectorAll(".rm-page-ref") returns every element it matches
.roam-body, .roam-app, .roam-main — the app shell
.roam-article — the main window's page content
.roam-sidebar-container — the left sidebar
.rm-sidebar-outline — a page open in the right sidebar
.roam-log-container — the daily notes view
.rm-title-display — page titles
.rm-block (also .roam-block-container) — a block together with its children
.rm-block-main (also .rm-block__self) — just the block's own line
.rm-block__children — the block's children
.rm-block__input (also .roam-block) — the rendered block text; while editing it is the textarea.rm-block-input
.rm-block: rm-heading-level-1 / -2 / -3, rm-block--open / rm-block--closed, rm-block--mine / rm-block--others, rm-block--editable / rm-block--readonly, rm-focused
.rm-page-ref — every page reference
.rm-page-ref--link for bracketed links, .rm-page-ref--tag for tags
.rm-block-ref — block references
.rm-reference-main — the linked references section (query results use it too)
data-tag (tags) or data-link-title (links), plus data-link-uid
data-page-links — a JSON array of every page linked in the block — and data-path-page-links for pages linked in its ancestors
#.aside. The tag will be automatically be hidden and appear on hover.
.rm-block container
data-block-uid, data-page-title, and data-create-display-name / data-edit-display-name
.roam-app {
font-family: "iA Writer Quattro", "Helvetica Neue", sans-serif;
}@import (e.g. a Google Fonts URL or a shared theme stylesheet) only works from the very first css block on this page — all blocks are concatenated into one stylesheet, and css requires @import at the top. Hosting a long theme on GitHub and importing it also keeps those lines out of your graph's search results
