CSS validator, HTML validator, using direct input option

I use the W3C CSS validator by direct input.


One of the most obvious features that appears to be missing is having a button to perform

the function of clearing the window of CSS code.


When there are errors,  a developer needs the ability to make changes  and re-validate their CSS.

Currently, the only way I can clear the code of the CSS Validator window is by selecting and cutting

it out before I am able copy and re-paste my fixed CSS code back into the W3C CSS validator.


A clear button would be appreciated by everyone that uses this free service..


Your feedback to this issue would be appreciated.
