Clay is Liferay's web implementation of the Lexicon Design Language. It is built with HTML, CSS, and Javascript with Bootstrap as a foundation.
You can view the various components on the Clay site.
If you would like to contribute, or make changes on your system you need to do the following:
Clone the repo to your computer
If you don't already have it installed. You can find more info here: http://nodejs.org/ Node and NPM come bundled together, so you only need to install one package.
Run npm install inside of the packages/clay-css directory
The files are generated from the src/ directory, however, most of the files you'd be interested in changing are in src/content/. Files can be either HTML (.html) or Markdown (.md).
Every file in src/content/ has a heading at the top in YAML format that looks something like:
---
title: Title of the Page
---
This section has a couple of options that can be leveraged for different purposes. Those will be covered below.
Run gulp build to generate the static files.
The generated files are placed into the build/ directory.
Sass files in the .scss format are generated to CSS, Markdown files with the extension of .md are generated to HTML, and HTML files have one bit of processing applied, which is that HTML inside of triple ticks is escaped, like so:
```
<div>Foo</div>
```
There are a couple of properties you can add to the headings of files, only one of which is required:
title:: (Required) This is used for the title of the page in the heading and in the navigation sidebar
navIndex:: The navigation is sorted alphabetically by default, but if you pass a navIndex: property, it will manually sort the item into that position.
The property is any number, with 0 as the first position, but you can also pass in a keyword of last to force an item to the end.
section:: If you want to group multiple files into sections, in each of those files, pass the same title to the section: property. That title will be used for the section heading, and the files will be sorted in there. The navIndex: property works inside of sections as well.
You can pass these options when running gulp.
build: This is the default task, so running just gulp will fire off the build task.
This will generate all of the HTML/CSS/etc into the build/ directory.
watch: Because running a script after every change can get tedious, run gulp watch to rebuild the files automatically as you change files.
serve: Starts a local server on port 3000 and also runs the watch task.
Bootstrap can be updated or downgraded by using the command:
npm install --save-dev --save-exact bootstrap@the_version
Popper.js can be updated or downgraded by using:
npm install --save-dev --save-exact popper.js@the_version
Then run gulp build or gulp-serve to compile Clay CSS with the new version
