Lingonberry

This is a sleek single-file CSS-only theme for CTFd I originally made for the ECSC Estonian finals. Feel free to modify and use it for your own CTFs.

Features

• Sleek lilac-pink color scheme and design
  • Buttons and input elements
  • New animations
• CSS-only
• Floating navbar
  • CSS tooltips on icon hover
• Dual-panel challenge list
  • New loading animation
  • Challenges are shown in a compact list instead of a grid
  • Challenge shows up as a side-pane instead of as a modal
    • Fallback to modals for small/phone screens
  • Highlight currently selected challenge
    • This is achieved with a pretty silly CSS-hack
• Challenge pane/modal
  • Solved challenges show up as such
    • Submit button replaced with a green Solved button
    • The pane glows green
    • This is achieved with that pretty silly CSS-hack from earlier
  • File downloads now have an icon corresponding to the format
    • This is achieved with some CSS selector hackery and CTFd's fontawesome icon font
    • Supported file formats:
      • archives (zip, rar, gz, tar)
      • images (png, jpg, bmp, gif)
      • code (php, py, js, c)
