# Ghost Admin App Ember.js application used as a client-side admin for the [Ghost](http://ghost.org) blogging platform. This readme is a work in progress guide aimed at explaining the specific nuances of the Ghost Ember app to contributors whose main focus is on this side of things. ## CSS We use pure CSS, which is pre-processed for backwards compatibility by [Myth](http://myth.io). We do not follow any strict CSS framework, however our general style is pretty similar to BEM. Styles are primarily broken up into 4 main categories: * **Patterns** - are base level visual styles for HTML elements (eg. Buttons) * **Components** - are groups of patterns used to create a UI component (eg. Modals) * **Layouts** - are groups of components used to create application screens (eg. Settings) All of these separate files are subsequently imported and compiled in `app.css`. ## Front End Standards * 4 spaces for HTML & CSS indentation. Never tabs. * Double quotes only, never single quotes. * Use tags and elements appropriate for an HTML5 doctype (including self-closing tags) * Adhere to the [Recess CSS](http://markdotto.com/2011/11/29/css-property-order/) property order. * Always a space after a property's colon (.e.g, display: block; and not display:block;). * End all lines with a semi-colon. * For multiple, comma-separated selectors, place each selector on its own line. * Use js- prefixed classes for JavaScript hooks into the DOM, and never use these in CSS as per [Slightly Obtrusive JavaScript](http://ozmm.org/posts/slightly_obtrusive_javascript.html) * Avoid over-nesting CSS. Never nest more than 3 levels deep. * Use comments to explain "why" not "what" (Good: This requires a z-index in order to appear above mobile navigation. Bad: This is a thing which is always on top!)
