# Concepts and tools

Ideas that run through the whole site, explained once so the role and component chapters can refer to them. The demo site's Demo section, <https://govcms.convivial.io/demo>, shows each in use on its banners and components:

* [Personalisation](/convivial-for-govcms/concepts-and-tools/personalisation.md) — audiences, intents, and content that changes per visitor.
* [Palettes](/convivial-for-govcms/concepts-and-tools/palettes.md), [Textures](/convivial-for-govcms/concepts-and-tools/textures.md) and [Overlays](/convivial-for-govcms/concepts-and-tools/overlays.md) — how colour and depth are applied to banners and components.
* [Modifiers](/convivial-for-govcms/concepts-and-tools/modifiers.md) — behaviours attached to a component: backgrounds, spacing, animation, visibility.
* [Component header](/convivial-for-govcms/concepts-and-tools/component-header.md) — the title, heading and introduction every component shares, and where they sit.
* [Hiding content](/convivial-for-govcms/concepts-and-tools/hiding-content.md) — the several ways to hide something, and which to use.
* [On this page](/convivial-for-govcms/concepts-and-tools/on-this-page.md) — the table of contents built from a page's headings.
* [Excluding from search](/convivial-for-govcms/concepts-and-tools/excluding-from-search.md) — keeping a page out of site search, the sitemap and search engines.
* [Accessibility](/convivial-for-govcms/concepts-and-tools/accessibility.md) — the editing habits that keep the site at WCAG 2.2 AA.
