Column-span not working

I'm towards the end of this, all working great, except now that we've inserted the H1 and using column-span it seems to have no effect.

<!DOCTYPE html>
    <title>Multi-column Layout</title>
    <link rel="stylesheet" type="text/css" href="page-styles.css">
    <link rel="stylesheet" type="text/css" href="style.css">

  -moz-column-span: all;

Not sure why this won't work?

hi, don't know if you solve the issue, but actually firefox doesn't support this property : [https://developer.mozilla.org/en-US/docs/Web/CSS/column-span].

I have switched to Chrome for my Treehouse and dev work. I like to use Brackets for my text editor and it has a live update feature that only works with Chrome. I don't like Google tracking my info, though.....

Brackets hey? Might have to look into that!

+1 for Brackets. I've tried them all, and this one is my favorite.

According to MDN, the prefix is -webkit, not -moz. Also, IE does not require the prefix, so if this is for a quiz you may need an entry without the prefix also.

That is odd. I used -moz- because the teachers notes included this reference http://caniuse.com/#feat=multicolumn. Plus I am using Firefox. It says it has partial support using -moz- prefix but doesn't mention anything about column-span being affected due to partial support. Oh well I'll switch to Chrome for this one I guess..
