Validating text

You need to check the The block of Java Script below the form is assigning our custom error message to the checkbox when the page loads.We know that the checkbox is unchecked by default so we need to tell the browser what message to display.Given the availability of inexpensive yet sophisticated web authoring tools, anyone can design a good looking site, but appearances are not necessarily indicative of the accuracy or timeliness of the information found on the site.What information is given so that you can determine who the owner is and what their experience is, the resources they used, etc., that will help you evaluate the content of their site?Does the color scheme make it difficult to impossible for those with color-deficient vision impairments, or who have trouble discriminating certain color combinations to read the information at the site (examples of problematic text/backgrounds: dark gray on black, yellow on white, red on green)?

While HTML5 form validation is typically about missing or invalid text inputs, there are other form element types that also require attention. Suppose you have a form on your website that at the bottom asks people to "accept the Terms and Conditions" or something similar.

If you're using Safari or another unsupporting browsers all the examples will just display the Java Script alert box.

As you would hope it is possible to customise the messages that are displayed by the browser with your own text, but this can only be done via Java Script.

The only hooks between them are the values for the form itself and the checkbox input element.

Also gone are any globally defined functions or variables.
