CSS
A styling language that determines the style and layout of a web page, including colors, fonts, and element positioning. CSS makes websites more visually appealing and user-friendly.
What is CSS?
CSS (Cascading Style Sheets) is the language that determines how a website looks. While HTML defines the structure of a page, CSS handles the visual presentation: colors, fonts, spacing, animations, and how elements adapt to different screen sizes. Without CSS, every website would look like a plain text document without any formatting or visual hierarchy.
How does CSS work?
CSS works by linking style rules to HTML elements through selectors. A selector determines which element is styled, and the associated declarations determine how it looks. CSS follows a cascade model: styles are applied from top to bottom, with more specific rules taking precedence. Modern CSS frameworks like Tailwind CSS use utility classes that allow developers to apply styles directly in the HTML, significantly speeding up the development process.
Example
Wabber builds a dashboard for a WMS used by warehouse staff on large screens and by pickers on compact handheld scanners. Using CSS and Tailwind CSS, a responsive interface is designed that automatically adapts to the screen size. On the large screen, the manager sees a comprehensive overview with charts and tables. On the handheld scanner, the picker sees only the essential information: the location and the product to pick. The same application, optimal on every device.
Why is CSS important?
Good CSS ensures that applications not only look professional but are also pleasant and efficient to use. The visual layer directly affects how quickly and accurately employees can do their work. Additionally, CSS makes applications responsive, ensuring they work optimally on any device: from a large screen in the office to a compact scanner in the warehouse. For businesses that deploy software across different devices, this is crucial.

Frequently asked questions
What is the difference between CSS and HTML?
HTML determines the structure and content of a web page: headings, paragraphs, images, and links. CSS determines how these elements look: colors, fonts, spacing, and positioning. HTML is the skeleton of a website, CSS is the styling. Both are needed to build a functional and attractive website.
What is Tailwind CSS?
Tailwind CSS is a utility-first CSS framework that enables developers to quickly and consistently build interfaces using predefined classes. Instead of writing custom CSS files, you apply classes directly in the HTML. Wabber uses Tailwind CSS for all its web applications because of the speed and consistency it provides.
What does responsive design mean?
Responsive design means that a website or application automatically adapts to the screen size of the device on which it is viewed. Using CSS media queries and flexible layouts, the same application is optimally displayed on a desktop, tablet, or smartphone. This is essential for businesses that deploy their software across different devices, such as office screens and handheld scanners.
