Understanding Dark Theme for All Websites

In this section, we’ll explore the concept of dark themes and their significance in web design.

Dark themes, also known as dark mode or night mode, invert the traditional color scheme of websites by using dark backgrounds and light-colored text. This design choice not only provides a visually striking aesthetic but also offers several practical advantages:

  • Reduced Eye Strain: Dark themes reduce the amount of blue light emitted by screens, which can alleviate eye strain, particularly during extended browsing sessions at night.
  • Improved Battery Life: For devices with OLED screens, such as smartphones, dark themes can significantly reduce power consumption, leading to extended battery life.
  • Enhanced Readability: Light text on a dark background can enhance readability, especially in low-light environments, by reducing glare and enhancing contrast.
