For those of us whose work revolves within the realm of browser compatibility, we always want to make sure that our CSS styling works perfectly as planned out. However, different browsers have different ways of implementing CSS properties and worse case, some of them are not supported by some of the most widely and commonly used browsers. CSS3.info provides a useful tool that will quickly test your browser which CSS selectors are supported or not by your browser(s).

The rotate tool is one of the most important tools in Illustrator. To duplicate a shape using the rotate tool, first select the shape if not selected and then select the rotate tool. Place the rotation point on the desired position and rotate the shape while holding Alt (hold Shift + Alt to get a perfectly 45D angle) to make the first copy and the fun part; press Ctrl-D (windows) Cmd-D (mac) repeatedly. By doing so, you’ll get an equal rotation spacing/distance between the shapes.

Using this magical tool, you could turn virtually any shape into a beautiful kaleidoscopic design, create patterns of shapes, add numerical characters to a clock or dial efficiently and lots, lots more.
