RTL guide: building Arabic websites that don't look "translated"

Arabic support isn't just dir="rtl" and done. These are the details separating professional sites from flipped templates:

Use CSS logical properties

/* instead of */
margin-left: 16px;
/* use — flips automatically with direction */
margin-inline-start: 16px;

Pick an Arabic font designed for screens

IBM Plex Sans Arabic, Tajawal and Cairo are excellent. Avoid fonts designed for print.
