Master one aspect
Go deep on one part of the platform: templates, partials, media, navigation, SEO.
Build a template (Liquid)Write the Liquid files that turn a page-type and its content blocks into rendered HTML, from the root layout down to a single element. Reuse blocks (partials)Factor repeated markup into partials, pass parameters explicitly, and dispatch a page's content blocks with a single include. Run a multilingual siteDeclare locales, translate content and interface strings, and make every link in your templates land on the right language. Manage media and imagesUpload once, let Quilium produce the sizes, render them with the right dimensions and a real alt text. Handle SEO and metasGive every page a real title and description, keep the pages that should stay out of the index out of it, and get detail pages right. Build navigation and menusRender menus from the site tree instead of hardcoding them, nest pages, hide what should not appear, and reorder without touching Liquid. Manage site-wide contentPut the address, the social links and the footer text in one editable place, and read them from any template. Consume an external feedRead a remote JSON endpoint at render time with an `api` field, key it on the item the page is showing, and handle the day it stops answering — which is the part that actually needs designing. Set up redirectionsKeep old URLs alive after a rename or a migration, without losing what search engines already know.
