While working on a tumblr theme, I noticed that even though Isotope's horizontal 'horiz' layout works perfectly in Safari, in Chrome and Firefox, the layout just doesn't seem to work. When I type something in the search box (filtering), the layout reloads properly, but doesn't seem to obey css height/width restrictions on the container. The page whose effects work in Safari but not in Chrome/Firefox : 01.
Desandro's horizontal layout example on codepen was working on all browsers, so to check if it may be tumblr messing up, I reduced the problem to exactly what DeSandro had written in his codepen example. Even then, it did not work on tumblr, in both Chrome and Firefox. It's working in Safari. The page of the reduced problem : 02.
It's important to note that the default layout, 'masonry', works on all browsers. I have not found anyone using Isotope's horizontal 'horiz' layout on a tumblr theme, so I cannot compare my theme with theirs or learn from them. Is this a possible bug on tumblr's part? If anyone can pinpoint the problem and explain what is going on here so that I can make the theme look like how it does in Safari, I would be so thankful!
