This test determines if your page has any inline style directives. Inline styles are both harder to maintain and require additional processing time so are not optimal. All style directives should be in dedicated CSS files instead.
Checking for inline styles
This test checks to see if any inline styles are detected in the page markup (eg. style=”). If any are found then the test reports a FAIL.
If you receive a FAIL for this test, you should consider moving your style directives to CSS files instead.
This test is based on a YSlow best practice. See http://yslow.org/faq/ for more details.
