App Frontend

App frontend definition: Difference from backend and more

What is an app frontend?

An app frontend is the graphical interface users engage with, including visual elements and interactive features like buttons and images. The frontend transforms complex functionalities into a user-friendly app design, allowing you to navigate effortlessly through the app.

From sleek visuals to responsive design, the app frontend ensures a positive user experience, while providing a seamless look and feel. Every tap or click interacts with the frontend, triggering actions and displaying information.

It's the bridge connecting you to the app's functionality, where aesthetics and functionality coordinate to create an engaging and accessible space for your digital interactions.

How is the frontend of an app different from the backend?

Where the frontend of an app is what you, as a user, see and interact with, the backend is like the engine room. The backend of an app is the server side that operates behind the scenes, handling data, processing requests and ensuring the app runs smoothly.

You can think of the backend as the portion of your app that doesn’t come into direct contact with your users.

So, when you tap a button in the app, the frontend makes it look good, while the backend does the heavy lifting, managing databases, handling server tasks and making sure everything functions as it should. Both the front and backend play a crucial role in delivering a top-notch app experience.

App frontend development languages

Although there are many programming languages you can use to do frontend development, HTML, CSS and JavaScript are the ones used the most. This is because they’re often integrated into a cohesive unit.

HTML provides the structure, CSS styles the elements and JavaScript adds functionality, forming the trifecta of front-end development.

1 - HTML

The hypertext markup language (HTML) can be considered the backbone of web content as it defines the structure and semantics of elements on a webpage. HTML creates the document structure, including headings, paragraphs, lists, images and links.

With HTML, you can use semantic tags like

to enhance the meaning of your content, which aids in search engine optimization (SEO). HTML also provides form elements for user input, such as text fields, buttons and checkboxes.

2 - CSS

CSS stands for cascading style sheets. CSS is used for styling HTML elements to make them visually appealing. It controls layout, colours, fonts and animations, ensuring the app looks polished and cohesive.

CSS enables the creation of responsive designs that adapt to different screen sizes and enhance the user experience of your app across devices. It also facilitates animations and transitions, adding dynamic visual elements to the user interface.

3 - JavaScript

JavaScript makes an app responsive and engaging. It is mainly used for adding interactivity, dynamic behaviour and client-side scripting to the frontend of an app.

It dynamically modifies the Document Object Model (DOM), allowing you to update the content and its structure without reloading the entire page.
