Over the last years, dark mode developed into a strong trend in web design. This alternative representation – in which light texts are presented on a dark background – is really appreciated by users globally. This is due to several reasons; for example, it is easier on the eyes and offers a modern and elegant look.
Websites that offer dark mode can benefit from a better user experience (UX). Users who browse at night or in dim lighting find dark mode more pleasant and less tiring on the eyes. Additionally, dark mode can help extend battery life, as it uses less energy. These benefits make implementing dark mode a valuable addition to modern websites.
An overview of dark mode
Giants like Google, Apple, Microsoft, Samsung, Facebook, Twitter, and a growing number of modern apps and websites now feature system-wide dark modes that can be quickly enabled or configured with just a few clicks.
Dark mode offers numerous benefits, both for users and for website managers:
- Eye comfort: Especially in dimly lit environments, users find dark mode more comfortable, as their eyes are less strained by bright screens. This can lead to longer visits to the website and increase user engagement.
- Energy saving: On devices with OLED and AMOLED displays, dark mode can help reduce power consumption, as dark pixels require less energy. This is a huge benefit for mobile users and improves the user experience.
- Modern look: Dark mode gives a website a sleek, contemporary look that is especially appealing to tech-savvy users. These aesthetic changes can help position a brand as innovative and forward-thinking.
Design principles for dark mode
Choosing the right colors and contrasts
Tips:
- To highlight content without straining your eyes, use light colors like light gray or pale white.
- Make sure colored elements, like buttons and links, stand out well against a dark background by using bright colors.
Optimizing images and graphics for dark mode
Tips:
- To accommodate both modes, use PNG or SVG with transparent backgrounds.
- Make sure images with white or light borders are adjusted to stand out against the dark background.
Dark mode typography and readability
Tips:
- For the main text, use a sans serif font: in dark mode, it looks cleaner and more modern.
- Adjust the line spacing (line height) to ensure that the text remains airy and easy to read.
Technical implementation of dark mode
CSS is a powerful tool for implementing dark mode. Using modern CSS techniques and media queries, dark mode can be designed to automatically activate if the user's system settings support it.
An intuitive approach to integrating dark mode is to provide a toggle switch that allows users to switch between light and dark modes. This gives users more control over their preferred view.
Implementation tip:
Use JavaScript to save and load the dark mode state so that users' preferences are retained when they revisit the website.
Design the toggle switch to be easy to find and intuitive.
Best practices for good dark mode integration
Benefits:
- Higher user satisfaction, as the website adapts intuitively.
- Time savings for users, as they do not have to switch modes manually.
Tip: Combine automatic dark mode detection with the ability to switch modes manually. This provides the greatest possible flexibility and improves the user experience. The technical implementation of dark mode should be functional and intuitive. Clean CSS integration, intuitive toggle buttons, and support for system settings help to effectively integrate dark mode into a website.
