Recently I wrote an article on using CSS `resize: both;`: https://www.bram.us/2020/05/15/css-only-resizable-elements/ In browsers that don't support this property I wanted to show a warning on screen to notify users thereof. For this I use an @supports rule: ```css .warning { display: block; } /* Hide warning in case browser supports resize: both; */ @supports (resize: both) { .warning { display: none; } } ``` I've come to notice that MobileSafari – which does not support `resize: both;` – hides the warning and thus falsely claims to support said CSS resize property.
