The patterns themselves should work on Firefox 3.6+, Chrome, Safari 5.1, Opera 11.10+ and IE10+. However, implementation limitations might cause some of them to not be displayed correctly even on those browsers (for example at the time of writing, Gecko is quite buggy with radial gradients).

The n-Category Café
Note:These pages make extensive use of the latest XHTML and CSS Standards. They ought to look great in any standards-compliant modern browser. Unfortunately, they will probably look horrible in older browsers, like Netscape 4.x and IE 4.x. Moreover, many posts use MathML, which is, currently only supported in Mozilla. My best suggestion (and you will thank me when surfing an ever-increasing number of sites on the web which have been crafted to use the new standards) is to upgrade to the latest version of your browser. If that's not possible, consider moving to the Standards-compliant and open-source Mozilla browser.

7 CSS Tricks That Actually Have Good Browser Support
Multiple-column layout, rows, rules, and floats
Recently implemented in Chrome are two of my top asks for CSS—the concept of rows in multiple-column layout, and gap decorations for rows and columns in grid, flexbox, and multicol. Rows (using column-wrap) provide a way to use multicol on the web without risking scrolling up and down to read if the columns become taller than the viewport. Gap decorations mean that, for multicol, you can now add a rule between these new rows. This post is a collection of the things I think would be interesting to do in future. If you think so too, and particularly if you have a great use case for any of these, let me know in the comments.
