From the Semantic directory you can setup gulp to build Semantic by running.
npm install
Semantic will automatically configure itself using a post-install
script built into the package.
After set-up can use gulp to build your project's css:
/* Watch files */
gulp watch
/* Build all files */
gulp build
Visit the Getting Started Guide for more details on set-up
Each gulp task can be imported into your own Gulpfile using require
var
watch = require('path/to/semantic/tasks/watch')
;
gulp.task('watch ui', 'Watch Semantic UI', watch));
LESS files do not contain vendor prefixes. If you are to use these files directly you must add them during your build step.
Before using source files you will need to create a theme.config
by renaming theme.config.example
, and a site folder by renaming _site/
to site/
You can then import Semantic from your own LESS files:
/* Import all components */
@import 'src/semantic';
To import individual components you will have to create a scope for each import using & {}
/* Import a specific component */
& { @import 'src/definitions/elements/button'; }
These files are generated automatically using install scripts, but must be manually renamed if you are using installing manually.
filename | usage | Initial Name |
---|---|---|
theme.config | config file that stores each element's current theme for LESS | theme.config.example |
site/ | folder storing all your site's variables and css overrides for each UI component | _site/ |
semantic.json | stores folder paths for build tools and current installed version for updates. Only necessary when using build tools | semantic.json.example |
You will only need to use Semantic's build tools while refining your UI. When designing pages, you can rely on the compiled css packages in dist/
.
When creating your UI you can try downloading different themes, adjusting your site-wide settings (font-family, colors, etc) and tweaking components in your site's component overrides.
Files in the examples/
folder of your project can be useful for testing out changes in your UI. For example, you might run gulp watch
download a new theme to src/site/themes/
then adjust your theme.config
file with the name of the new theme and refresh examples/kitchensink.html
to inspect changes in the theme.
There are three levels of inheritance in Semantic
- Default theme - Semantic UI's neutral default theme
- Packaged theme - A specified packaged theme, like "amazon", or "material"
- Site theme - A theme specific to your site

The best way to start customizing is to specify overriding variables in your site's site.variables
file.
This is a blank stub file that lets you specify variables that overriding variables.
Some important values to customize:
- Base font size
- Named color hex codes
- Header/Page Font-families
- Primary and secondary colors
- Grid column count
To find out what variables are available to modify, you can inspect the variables in the default theme in themes/default/
Each component has its own variable file, which can be used to modify any of the underlying variables for that component.
For example /site/elements/button.variables
.
You may also specify your own custom LESS in site/elements/button.overrides
. This file will have access to all underlying variables available for that component.
You can modify theme.config
to use any prepackaged theme available in src/themes/
.
For example you can modify theme.config
to use a github
button theme by changing
@button: 'github';
