OpenEMR-interface

The OpenEMR UI is built with SASS on top of a bootstrap base (compiled with gulp).

Themes

Different themes share a common core and have their own overrides to customize the appearance of OpenEMR.

There are three different types of themes:

• The light theme is the default modern theme
• The manila theme is a combination of OpenEMR's legacy themes (which have all been removed) with some modern elements.
• The other themes (called colors) are the same color_base theme with different color palettes.

rtl_ prefixed themes are built by appending the rtl.css file to every theme automatically. These overrides provide right to left adjustments for all style*.css files

Files specific to different themes are named with the following conventions:

• themes/core contain shared styles that all themes import toward the top of their files
• themes/colors contain all changes specific to the color theme work (led by zbig01)
• themes/[component_name] (e.g. buttons or navigation-slide) contain files named after each theme variant.
  • See TODOs on how we might be able to manage component-level styles in the future

Special Classes

• position-override gives a hook for style to change placement of buttons. In light/manila style this is ignored and buttons go to left positioned under data entry field. Whereas in the other styles this is used to center the buttons.

Getting Started

Compiling SASS files locally requires node.js and npm.

1. Setup your local development environment as described in CONTRIBUTING.md

• If running on a local machine, run npm install from the root directory.
• If running in docker: docker exec -it [your_container_id] /bin/sh then cd into openemr

From here you can either:

• npm run dev - just compiles the local .scss files and recompiles them whenever they are changed.
• npm run dev-sync (EXPERIMENTAL*) - loads your local OpenEMR instance using BrowserSync (port 3000) in front of 80 (feel free to edit the package.json to change the port)
  • See video of dev-sync in action

TODOs

• Incorporate tabs_style_compact.css and tabs_style_full.css (and associated RTL) into scss
• Don't require 2 build runs to build the rtl themes
• Add a lot of documentation on current component usage (starting with theme-only components)
• Migrate style dependencies in the php code to use the components from the interface directory
• Migrate component css still left in the /themes directory into scss
