Required Technical Skills
HTML & Markup
•Strong command of semantic HTML5: sectioning elements, headings hierarchy, lists, tables, and forms.
•Solid grasp of web accessibility (WCAG 2.1 AA): ARIA roles and attributes, keyboard navigation, focus management, alt text, and accessible form labeling.
•Familiarity with structured data and SEO markup: meta tags, Open Graph, Twitter cards, and Schema.org/JSON-LD.
•Understanding of how Drupal renders markup through Twig, and the ability to produce clean, valid output via template overrides.
CSS & Styling
•Deep working knowledge of modern CSS layout: Flexbox and CSS Grid, with sound judgment about when to use each.
•Proficiency with responsive design: media queries, fluid typography, container queries, and mobile-first methodology.
•Command of the cascade, specificity, and inheritance, with the ability to debug specificity conflicts rather than reaching for !important
•Comfort with CSS custom properties (variables), modern color/spacing tokens, and maintainable theming patterns.
•Awareness of cross-browser compatibility, vendor prefixing strategy, and progressive enhancement.
Nice to Have
◦Strong SCSS/SASS skills: nesting, mixins, functions, partials, and a disciplined file architecture.
◦A consistent CSS methodology such as BEM, and an understanding of how it maps onto Drupal's class conventions.
◦Familiarity with CSS transitions, transforms, and animations, used with attention to performance and reduced-motion preferences.
JavaScript
•Solid command of modern JavaScript (ES6+): arrow functions, destructuring, modules, promises, and async/await.
•Strong DOM manipulation and event-handling skills, including event delegation and performance-conscious listeners.
•Fluency with the Fetch API and asynchronous data handling, including JSON parsing and error handling.
•Working knowledge of Drupal's JavaScript layer: Drupal.behaviors, once(), drupalSettings, and the AJAX framework
•Understanding of how to attach and scope JS correctly through the Libraries API rather than inline scripts.
•Familiarity with debugging via browser DevTools: breakpoints, the network panel, performance profiling, and the console.
Nice to Have
◦Awareness of frontend performance: deferring/async loading, minimizing reflows, debouncing/throttling, and avoiding render-blocking scripts.
◦Experience with a build/tooling pipeline (Webpack, Vite, or Gulp) and with linting/formatting (ESLint, Prettier, Stylelint).
◦Exposure to a modern framework (React/Vue) is a plus, particularly for decoupled or partially decoupled Drupal frontends.
