Such a perfect showcasing of a custom typeface in this One Pager for Scope by Jonas Pelzer. The Single Page website begins with an cursor-interactive axis changing weight and width (including changeable text), a scheme switcher, examples, a typetester, the character set and ends with purchase links. Well played Jonas and cheers for the build notes!
I used Glyphs to create the variable font. The site is built in HTML, CSS and jQuery, making extensive use of the CSS property "font-variation-settings". Like most of my work, the project went straight from my sketchbook to code. No further prototyping tools involved.
