ebay-font is the module used at eBay to load custom web fonts. It uses a strategy to avoid both FOUT and FOIT. This can be considered equivalent to the new CSS @font-face descriptor font-display: optional. Unfortunately, font-display is relatively new and hence its adoption among browsers is not widespread. So for now, this module leverages localStorage, FontFaceSet API and the Font Face Observer utility (as a backup if FontFaceSet API is not present) to provide the same functionality as font-display: optional.
ebay-font is paired along with eBay's custom font 'Market Sans'. But feel free to change it to any custom font URL of your choice.
Please refer to the detailed blog post "eBay’s Font Loading Strategy" for a full overview of how this module works.
ebay-font can be used along with other eBay open source modules Skin, Marko & Lasso, as well as in standalone mode. If you are in the eBay workflow environment, please follow the below steps
