The Tools
Most tools in this section can be used from this site. They are mainly related to developing according to W3C ➚ standards. But in time there will be other stuff to i hope.
The W3C CSS validator
Use the css form to validate your CSS.
The W3C (X)HTML validator
Use the html form to validate your (X)HTML.
The Cynthia validator
Use the Cynthia validator to validate your accessibility.
AccessColor Tool
The AccessColor Tool ➚ tests the color contrast and color brightness between the foreground and background of all elements to make sure that the contrast is high enough for people with visual impairments.
Assuring that you provide enough color contrast between foreground and background colors takes time and this tool will help web developers to build accessible websites by visually flagging the section(s) of a page with problematic color combinations. AccessColor will find the relevant colour combinations within your HTML and CSS documents rather than requiring you to find each value to input yourself in order to test the contrast between each colour combination.
