Frontend development
As part of our frontend development services, we mainly turn visual designs into working website and web application templates. The main languages we work with are HTML, SCSS and JS. We build code based on frameworks and tools such as Bootstrap, Gulp, Vue and Webpack.
We pay great attention to clean code, optimised components and application speed. Thanks to current libraries and tools, you can be sure that the code we prepare will be correctly implemented and well received by backend developers and the deployment team.
You can build the front end of your application with us using your own visual design, or ask us to design it as part of our web design service.
Frontend development is part of the wider process of building web applications, online stores and websites.
In the dynamic world of website development and web applications, frontend developers play a key role in shaping the digital experience that users interact with every day. They are the architects of the user interface, responsible for creating the visual and interactive elements of websites and web applications.
A frontend developer plays a key role in shaping the user experience on the web. They work with a wider team of UX designers and developers to create what users see and interact with in their web browsers. To achieve this, frontend developers use a toolkit that includes HTML5, CSS, JavaScript, JavaScript frameworks and code libraries.
At the heart of frontend development are three key languages: HTML5, CSS and JavaScript. They are the foundation of the whole frontend environment. Over the years they have evolved and improved, allowing developers to create richer and more dynamic web experiences.
HTML, the HyperText Markup Language, is the foundation of building websites. It defines the structure of a site and the basic elements that determine how a page should look. HTML can format text, set features such as bold or italics and arrange content into paragraphs.
However, HTML alone has limitations when it comes to design and styling. This is where CSS, Cascading Style Sheets, comes in. CSS is a language designed to control the visual presentation of web pages. Frontend developers use CSS to apply styling changes consistently across a site. With just a few lines of CSS, you can change the colour of every heading, creating a consistent and attractive look.
The third element is JavaScript, a dynamic scripting language that adds interactivity and responsiveness to web pages. The early days of the internet were marked by the frustration of waiting for pages to load and refresh, especially on slow dial-up connections. JavaScript changed that experience by letting developers manipulate page elements in real time, removing the need to keep refreshing the page. It is JavaScript that powers real-time updates on social media, making the web dynamic and responsive.
Frontend developers do not work in isolation: they use various tools to streamline their work and improve the user experience. Frameworks and code libraries are essential here. Frontend frameworks such as Vue.js make it easier to build advanced user interfaces and help developers work more efficiently. jQuery, in turn, simplifies common JavaScript tasks, which makes coding traditional websites faster and easier.
In addition, AJAX (Asynchronous JavaScript and XML) extends what JavaScript can do by allowing web pages to update dynamically without a full page reload. AJAX uses XML, a markup language, to make data exchange between the frontend and the server easier, which further improves the user experience.
In summary, frontend development has come a long way since its beginnings. Today’s frontend developers have a powerful set of languages, frameworks and libraries for creating visually impressive, interactive and responsive websites. They are indispensable in bringing user expectations together with technological possibilities, making sure the internet remains a dynamic and attractive place for everyone.
Frontend development - nasze standardy
Vue, JS, HTML, SCSS
We use modern coding languages that let us implement even the most demanding templates and visual effects.
Gulp, npm
We use libraries that automate and optimise coding, builds and versioning. This lets us work efficiently in teams and on a consistent development environment.
Bootstrap framework
We base our templates on Bootstrap's 12-column grid system, which ensures quality, compatibility and ease of implementation during further development and changes.
FAQ - Frontend development
Of course. You can order frontend development on its own, and we can also become part of your team and take responsibility for the frontend layer of your IT project, which happens quite often in our work.
Frontend development and backend development (for example Symfony PHP) are responsible for everything you deal with on the internet, all day, every day. Frontend development uses frontend programming languages to create what the user sees in the browser; backend development uses backend programming languages to handle those requests on the server side. Together they create a consistent experience for the user.
Going a little deeper, this very page was built with three frontend languages. The words you are reading are written in HTML. The spacing and colours are defined by CSS. The interactive graphics are the work of JavaScript. Backend languages working in the background include Ruby, Python and PHP.
Let’s put the technical side aside for a moment. In many ways it is similar to a city or a house. A city has a surface level that you interact with and the infrastructure that supports it, such as the water system or the power grid.
But there is always something you see and something that works behind that visible layer. In a house, the foundation and structure can be thought of as HTML. CSS adds the design elements, while JavaScript can be responsible for all the things that turn a house into a home. The backend can be compared to public utilities and other essential services.
The work of a frontend developer is demanding and requires a variety of skills to create attractive and functional user interfaces. Here are the essential skills:
- HTML: frontend developers must know HTML (HyperText Markup Language) inside out, because it is the basic language for building the structure of a web page.
- CSS: Cascading Style Sheets (CSS) define the look and styling of web pages. Understanding CSS is key to creating attractive designs.
- JavaScript: JavaScript is the programming language used to add interactivity and dynamic behaviour to web pages. Frontend developers must be able to write, debug and optimise JavaScript code.
- Developer tools: using the developer tools built into web browsers (for example Chrome DevTools) is essential for debugging and testing frontend code.
- Responsive design: the ability to build pages that look and work well on all kinds of devices, from desktop computers to smartphones and tablets.
- CSS preprocessors: frontend developers often use CSS preprocessors such as Sass or LESS to make creating and managing style sheets easier.
- Frontend frameworks: understanding and being able to work with popular frontend frameworks such as React, Angular or Vue.js is useful for building advanced web applications.
- Version control: working with version control tools such as Git is essential in a development team for tracking and managing code changes.
- Performance optimisation: frontend developers need to know how to optimise a website for performance, including loading time and performance on different devices.
- Testing and debugging: the ability to test code, find and fix bugs (debugging) and ensure the quality of frontend code is essential.
- Accessibility: understanding accessible design principles (for example for people with disabilities) is important to make sure websites are available to all users.
- Teamwork: frontend developers often work in a project team, so communication, collaboration and knowledge sharing are key.
- Creativity and aesthetics: the ability to create aesthetic, visually pleasing designs is important for making websites attractive.
- Problem solving: frontend developers often face a variety of challenges when building interactive elements, so problem-solving skills are key.
- SEO: understanding the basics of search engine optimisation (SEO) helps create websites that are more visible in search results.
These skills allow frontend developers to create attractive, responsive and interactive websites that meet users’ expectations and are a key element of the success of online projects.
