"Light-weight spinner indicator (ASCII)"

Questions / Comments:

Thanks for feedback. I switched to standard ASCII, should work everywhere. I tested on Mac / Linux and iPhone / Android. (buttons not working on Android thought - I'll work on that). I added my FontAwesome snippet link.

Thanks for feedback. I switched to older ASCII characters - should work now. I tested on Mac/Linux/iPhone. on Android, buttons are not working. But it should "spin" on all platforms / browsers.

What platform? Win or Mac?

maxsurguy () - 10 years ago - Reply 0

Chrome 33 on Win 7 and Mac. Not sure that's a bug, but Chrome has issues rendering some unicodes, looks like it depend on font-family. Take a look here http://unicode-table.com/en... they use a custom font to show the correct character but pay attention to "search result", shows the square when font-family is "Arial, Helvetica, sans-serif". I guess the problem could be an unhandled fallback when the font-family doesn't have the requested character.
Chrome 33, FF 26 on Linux Mint 15 (Ubuntu 13.04) and IE on W7 they work ok

Thank you for that detailed report, maybe a solution is to specify a font that is most likely to be on any platform?

maxsurguy () - 10 years ago - Reply 0

Not sure. In the past I solved similar situations by detecting OS and browser and replacing characters by images, but I think an elegant and crossplatform solution is setting a font (as a gliphicon font) containing the desired chars/icons.

Yeah I was thinking of that too, would be nice to see some of the icon fonts implement this feature, could make some really loading indicators that way. Thanks for your feedback!

Doesn't show anything for me either. (Running Chrome on Debian Wheezy.)

Doesn't work: XP x86 - Opera 21, Firefox 27 ( shows hexa value of character? ), Chrome 33

>It doesn't show any indicator.. -- Which OS, and Browser and versions? I've tested in Safari, FF, Chrome.. it should work, nothing fancy or too new here. Please advise, I will fix it. thanks Rob
