Getting started

This projects uses https://github.com/andybelldesign/hylia

Terminal commands

Serve the site locally

npm start

Build a production version of the site

npm run production

Compile Sass

npm run sass:process

Re-generate design tokens for Sass

npm run sass:tokens

Getting started with the CMS

Before you can use the CMS, you need to do some config in Netlify. Luckily they provide a very handy guide to get started.

In short, though:

  • Once you’ve set up the site on Netlify, go to “Settings” > “Identity” and enable Identity
  • Scroll down to the “Git Gateway” area, click “Enable Git Gateway” and follow the steps
  • Click the “Identity” tab at the top
  • Once you’ve enabled identity, click “Invite Users”
  • Check the invite link in your inbox and click the link in the email that’s sent to you
  • Set a password in the popup box
  • Go to /admin on your site and login
  • You’re in and ready to edit your content!

Design Tokens and Styleguide

Design Tokens

Although Hylia has a pretty simple design, you can configure the core design tokens that control the colours, size ratio and fonts.

Note: Credit must be given to the hard work Jina Anne did in order for the concept of design tokens to even exist. You should watch this video, then read this article and then sign up for this course to expand your knowledge.

To change the design tokens in the CMS, find the “Globals” in the sidebar then in the presented options, select “Theme Settings”.

To change the design tokens directly, edit _src/data/tokens.json.

The tokens are converted into maps that the Sass uses to compile the front-end CSS, so make sure that you maintain the correct structure of tokens.json.

Styleguide

Your version of Hylia ships with a Styleguide by default. You can see a demo of the Styleguide at https://hylia.website/styleguide/.

You can edit the Styleguide by opening src/styleguide.njk. If you don’t want the Styleguide, delete that file and the page will vanish.

Sass

Hylia is based on the WIP v2 version of Stalfos, which currently has no documentation (I know, I’m bad). Here is some very basic documentation for elements of the new framework that you will encounter on this project.

Configuration

The whole Sass system is powered by central config file, which lives here: _src/scss/_config.scss.

Before Sass is compiled, a _tokens.scss file is generated from the design tokens config which is required.

Key elements:

  • $stalfos-size-scale: A token driven size scale which by default, is a “Major Third” scale
  • $stalfos-colors: A token driven map of colours
  • $stalfos-util-prefix: All pre-built, framework utilities will have this prefix. Example: the wrapper utility is '.sf-wrapper' because the default prefix is 'sf-'
  • $metrics: Various misc metrics to use around the site
  • $stalfos-config: This powers everything from utility class generation to breakpoints to enabling/disabling pre-built components/utilities

How to create a new utility class with the generator

The utility class generator lets you generate whatever you want, with no opinions on class name or properties affected.

To add a new class, add another item to the exists $stalfos-config map. This example adds a utility for floating elements.

'float':('items':('left':'left','right': 'right'
  ),
  'output': 'responsive',
  'property': 'float'
);

The output is set to responsive which means every breakpoint will generate a prefixed class for itself. If you only wanted elements to float left in the md breakpoint, you’d now be able to add a class of md:float-left to your HTML elements.

If you only want standard utility classes generating, set the output to standard.

Functions

get-color($key)

Function tries to match the passed $key with the $stalfos-colors map. Returns null if it can’t find a match.

get-config-value($key, $group)

Returns back a 1 dimensional (key value pair) config value if available.

get-size($ratio-key)

Function tries to match the passed $ratio-key with the $stalfos-size-scale. Returns null if it can’t find a match.

Mixins

apply-utility($key, $value-key)

Grabs the property and value of one of the $stalfos-config utilities that the generator will generate a class for.

media-query($key)

Pass in the key of one of your breakpoints set in $stalfos-config['breakpoints'] and this mixin will generate the @media query with your configured value.

CMS

Hylia has Netlify CMS pre-configured as standard. You can customise the configuration by editing src/admin/config.yml.

Content that you can edit

The basic CMS setup allows you to edit the following:

  • Home page: Edit the content on your homepage
  • Posts: Create and edit blog posts
  • Generic pages: Create generic pages that use a similar layout to posts
  • Global site data: Various bits of global site data such as your url, title, posts per page and author details
  • Navigation: Edit your primary navigation items
  • Theme: Edit the design tokens that power the site’s theme
