Recipe A.3 Tools
Recipe A.3.1 SelectORacle
A free service
to help people learn more about complex CSS selectors by
translating their meaning into plain
English. CSS selectors can be submitted in one of two ways. The first
method is to copy and paste a CSS selector into the form. The other
method is to enter either a URL of a web page with an embedded style
sheet or a URL to an external style sheet. The service then renders
the CSS selector into easy to understand language.
Recipe A.3.2 W3C CSS Validator
This free service, provided on the W3C server,
checks CSS for proper structure. You can test your markup by
uploading files, entering a web address in the form, and then copying
and pasting the CSS into a form field. And if you are so inclined,
you can download and install the validator on your own server.
Recipe A.3.3 W3C HTML Validator
The W3C HTML validator is another free service
from the W3C. Similar to the CSS validator, the HTML validator checks
to see if your markup conforms to web standards.
