1. When aiming to support as many browsers as possible, which of the following is the optimal choice?:
-webkit-transform: rotate(30deg);
-moz-transform: rotate(30deg);
-ms-transform: rotate(30deg);
-o-transform: rotate(30deg);
transform: rotate(30deg);
Additionally, does jQuery provide a solution to set just one property that will address browser differences?
2. What are the performance differences between using pure JS and jQuery? How can this be implemented in pure JS for 100-300 items requiring fast updates?
