SlickSpeed Selectors Test

speed/validity selectors test for frameworks.

Every framework runs in its own iFrame, thus no conflicts can happen. Tests are run selector by selector, with an interval to prevent the browser from freezing.

Tests are run in a neutral environment, no library or framework is included in the main javascript test, to avoid favoritism.

The WebKit version of this test includes a number of modifications. Specifically

The tests are run 250 times instead of once to show speed differences more accurately

querySelectorAll is added as a supported “library”

CSS selectors that not all implementations support have been removed to avoid distorting timing results. These will be added back in as new selectors are implemented.

CSS LINT

CSS Lint is a tool to help point out problems with your CSS code. It does basic syntax checking as well as applying a set of rules to the code that look for problematic patterns or signs of inefficiency. The rules are all pluggable, so you can easily write your own or omit ones you don’t want.
