Feature list

• Layout:
  • Advanced Flex system for painless flexbox layout.
  • Simple and flexible Grid system for literally any layout you can think of.
  • Classes for margin and padding vertically, horizontally, on all sides, and on each side individually, for ultimate control.
  • Margin, padding, height, width, and Jupiter components all obey REM values for giving your user the best looking experience possible.
  • Utility classes and modular layouts for painless sectional building without stumbling over classnames.
• Misc. Styles:
  • Excellent color support with static colors, like black and white, or dynamic colors, which vary between dark and light mode. Of course, there are also classes for background colors and font colors which obey the specific, extensive list of colors that Jupiter offers.
  • Excellent box-shadow styles.
  • Painless support for blurred backgrounds (via backdrop-filter)
• Excellent, REM-based typography
• Components (typically) have tons of additional classes for extra customization.
• Excellent accessibility classes like .sr-only
• Issues are generally fixed immediately.
• There's usually a release that adds functionality in a backwards compatible manner every few weeks or so. Changes are made far more often.
• The design is updated every so often as tastes in UIs change.
• Hassle-free, essentially zero setup required for modifying Jupiter. It is, quite literally, two commands: one to install the NPM packages and one to start the GruntJS script to watch the source files. Effortless.
