Uuups – experimental WordPress Theme

Uuups is an experiment how to bring your theme to the next level.

1. The theme uses modern PHP, JS, CSS, and other tools.
2. The theme also attempts to stick with WP standards so that it doesn't feel too foreign.

Version from Mythic

This is my playground from Justin Tadlock's starter theme called Mythic. Most of the code is the same but I have small experiments here and there.

Documentation

Read documentation from Mythic Wiki.

Demo

Demo can be seen in Foxland site.

My wishlist

I have hopes and dreams for the starter theme:

• Accessibility ready out of the box.
• Clean semantic HTML without lots of extra DIVs
• Scalable, modular CSS/SASS architecture. It should guide developers how they write their CSS.
• Ready for Gutenberg and a maximum WYSIWYG experience.
• ES6 for JavaScript.
• Gulp, Webpack, or npm scripts for automated tasks like - compiling assets.
  • optimising images and SVGs.
  • CSS, JS, and PHPCS linting.
  • SVG system.
• Being design system ready.

My workflow

I'll work on dev branch where I keep un-minified CSS, JS, SVGs etc. In master all assets are cleaned and compile when running npm run build.

In other words master branch is ready for production.

Accessibility testing

Pa11y runs your code against HTML CodeSniffer. Check documentation from pa11y site.

On the command line test any local or live URL:

I recommend also aXe browser add-on or aXe-CLI.

CSS structure

CSS structure is probably one of the biggest aspects of the front-end and theming. It should have scalable and modular architecture.

Styles are written in resources/css folder. There are two separate stylesheets which are automatically compiled to dist/css:

• style.scss – Main stylesheet for the theme.
• editor.scss – Stylesheet only for the block editor (Gutenberg).

Main stylesheet

Main stylesheet style.scss follows ITCSS approach and BEM naming convention.

The main point of ITCSS is that it separates your CSS codebase to several sections (layers). It guides you to write CSS from low-specificity selectors to more specific ones.

It also plays nicely with the new editor (Gutenberg) because block styles can be one of the layers.

We should write separate documentation about SASS and CSS, it's that important.

Styles for the editor

editor.scss tries to put all the necessary styles to the new editor without re-writing front-end styles.

Note a little trick where we prefix all the styles with class editor-styles-wrapper using postcss-editor-styles plugin.

New editor (Gutenberg) support

At the moment support for new editor means these things to me:

• Add support for editor-color-palette to match theme colors.
• Add support for editor-font-sizes to match theme font sizes.
• Add support for align-wide blocks.
• Dequeue Core block styles:
  • This is because I don't want to overwrite and add too spesific rules to main stylesheet.
  • Core blocks have their own CSS layer as mentioned before. It can be found in recources/css/blocks.
• Get maximum WYSIWYG experience in the editor by enqueueing block related styles using enqueue_block_editor_assets hook.

See previous chapter styles for the editor.

Coding standards and linting

Theme mostly follows WordPress coding standards.

There is pre-commit hook which runs PHP, Style, and JavaScript linting before new commits can be pushed to repo.

For example if there are changes in CSS files, it runs npm run lint:css before the commit.

You can use --no-verify flag to bypass linting check:

All lints can be run by command npm run lint. Or use any of the following lint commands.

PHP linting

NPM task npm run lint:php checks PHP files using WordPress coding standars (WPCS). In .phpcs.xml.dist there is custom PHP ruleset Foxland-Default which extends WPCS. This is loaded via composer package.

Style linting

NPM task npm run lint:css checks CSS files using stylelint.

File .stylelintrc is the configuration file for stylelint.

I also recommend installing stylelint extension to your IDE, for example vscode-stylelint.

JavaScript linting

NPM task npm lint:js checks JS files using ESLint.

File .eslintrc.js is the configuration file for ESLint. And .eslintignore file for what files to ignore from linting.

I also recommend installing ESLint extension to your IDE, for example VS Code ESLint extension.

Run your code automatically through Travis CI

When you commit changes in Github, let Travis CI run and test your code.

File .travis.yml is the configuration file for setting up Travis.

Editorconfig

Theme has an .editorconfig file that sets your code editor settings accordingly. Download the extension to your editor. The settings will automatically be applied when you edit code when you have the extension.

New version

Generate .zip file using command:

For example:

This will generate zip file releases/uuups-1.0.0.zip.

SVG system

All the main SVG related functions can be found in the app/functions-svg.php file. It’s well-documented in the code, but here’s a summary:

• Add SVG icons in resources/svg folder. npm run dev or npm run build copies these SVG files in dist/svg folder.
  • In the same cleans them up.
  • Adds attributes and classes for using these icons as decorative only.
• Uuups\get_svg() function returns inline SVG icon markup by default.
• For example Uuups\get_svg( [ 'icon' => 'folder-open' ].
• SVG icons are automatically used in Social links menu.

If the SVG is not decorative, add SVG markup directly in the markup.

FAQ

What about sidebars?

For old themes I probably would not try to add align-wide support if child themes can be broken.

For new themes you can definitely have "wide" and "full-width" blocks even if there is sidebar on the right or left.

Yeah but how? Using CSS :)
