A very recent change that has been deployed is preventing me from asking new questions or editing existing questions using Internet Explorer 11. (Yes, it is a supported browser.)

When asking a new question or editing an existing one, the tag bar appears in plain text, and the submit button is always disabled.

enter image description here

Why is this happening?

    I'm not 100% sure but I think in tageditornew.en.js this line needs fixing: editor.addClass("s-input").css({paddingTop: 0, paddingTop: 0}); the double paddingTop is not allowed. – rene Jul 19 '18 at 19:43
  • yep, that's it @rene – Shog9 Jul 19 '18 at 19:53
  • blame a relaxed jslint rule ... – rene Jul 19 '18 at 20:00

As rene pointed out in the comments, this appears to have been triggered by a newly-added bit of code in the tag editor which tries to set the same property twice in a single call.

That's... likely a typo; I changed one of the paddingTop properties to paddingBottom and the page loads on IE just fine.

This fix should now be live.

  • Correct CSS is "padding-top", not "paddingTop" - no? Unless CSS changed drastically since I learned the basics and it allows JS style syntax? Anyway, guess jQuery changes it by itself otherwise it wouldn't be working at all, just neat picking here. :-) – Shadow Keeps Social Distance Jul 19 '18 at 21:39
  • @ShadowWizard The DOM style properties JS interacts with are camel case. – Alexander O'Mara Jul 19 '18 at 21:43
  • CSS also doesn't care about duplicate rules, @Shadow. The jQuery call - .css({style properties}) - takes an object, and JS sometimes does mind duplicate object properties. Note also that while the CSS property is padding-top, the equivalent DOM property is paddingTop - not that this is relevant. – Shog9 Jul 19 '18 at 21:44
  • Well, I'm using that .css({style properties}) myself sometimes, but always gave the "CSS case", not JS camelCase. Admit that I never looked into it, just seemed like the proper way. Anyhow... thanks for the quick fix, on behalf of all the IE11 users! :) (Which I'm not among them.) – Shadow Keeps Social Distance Jul 19 '18 at 21:54
  • @ShadowWizard jQuery allows you to pass properties either as camelCase or as in CSS. It then internally converts the names into camelCase. – Toothbrush Jul 20 '18 at 8:26
