Front-end Test Project

Project brief

Convert the following designs to HTML/CSS/JS.


Xfive Front-end Test Thumbnails


Xfive Front-end Test Overlay


  1. Create project using Chisel
  2. Use HTML5 / SCSS
  3. Make it responsive using your best judgement.
  4. Create a simple custom overlay for photos - use only vanilla JavaScript, do not use jQuery or any other external libraries for it.
  5. Create some hover effect for the image thumbnails.
  6. Make the page the smallest possible size - ensure that images are properly optimized, resources minified, etc.
  7. Optional bonus task 1: Make images responsive
  8. Optional bonus task 2: Add basic routing – make browser's back button work properly; open overlay based on URL.
