HTML & CSS Expertise

Create modern, accessible and perfectly responsive web interfaces with our mastery of HTML5 and CSS3.

HTML5 & CSS3: the foundations of a modern web

Web integration is much more than simply translating mockups into code. It is the art of creating semantic, accessible and performant interfaces that work across all devices.

A truly modern web is a web open to everyone, on every screen.

Devoptus masters fundamental front-end technologies: CSS Grid and Flexbox for complex layouts, CSS3 animations for smooth transitions, Sass and BEM methodology for organized and maintainable code. Our mobile-first approach ensures optimal display from smartphone to large screen.

Accessibility and compliance at the heart of our integrations

We pay particular attention to web accessibility (WCAG 2.1): keyboard navigation, screen reader support, sufficient contrast and ARIA attributes. Every integration is validated against W3C standards for clean and interoperable code.

Our integrations are optimized for performance: critical CSS, lazy loading, minification and sprites for minimal load times. The result: pixel-perfect interfaces that are fast and compatible with all browsers.
