   OXYGENI HAIR CARE – biokadeřnictví Karviná
   Písmo: Lora (nadpisy) + Jost (text), zvoleno kvůli čitelnosti.
   Layout: redakční jednostránka ve stylu šablony Sorrel Lite (Mike Smith Design,
   https://github.com/mikesmithdesign/sorrel-lite) – velká patková typografie,
   fotografie v obloucích, seznam služeb s výměnou fotky, tmavé pásy.
   Barvy: bílá + modré odstíny Oxygeni (navzorkováno z loga a materiálů),
   pás NATULIQUE v krémové a čokoládové barvě značky.
   Vědomě jen světlá varianta (zadání: bílý web).
