• [x] change caret design with FA icon https://fontawesome.com/icons/caret-down
• [x] Change the copy button. What is it copying? just the code line? then in the code box
• [x] do not put the argument in a second line in the code exemple
• [x] Maybe add "()" to function title
• [x] change/keep the style of the box of the description
• [ ] revise the "update time"... ugly...
• [x] Is there anything to add below the how to use ? e.g. "how to cite?", "contact?/ the creator", "used in ...", logo of unil, gaia etc...
• [x] favicon
• [x] check for logo

• I add the caret, put the argument on the same line, and (...), and update the description box class
• How to cite the lib or each algorithms ? Each algorithm as it own license , we could add a small flag each time, no ? for the logo, we could add some let me check
• If you have idea for the update time, feel free to change.
• The copy button copy a sequence ready to be use in GEE, it's not exactly the same a code box content
