Editing a CSS file to apply a ABAP WD theme

Hi ,

Requirement is to apply a theme to ABAP Web Dynpro applications with a back ground color,font size,font colors.

So,in the MIME i have downloaded the CSS and manually edited the background color,exported into MIME after editing.

Changes are reflected.But how to I interpret this CSS for other properties?

Is any CSS editor available for SAP users.

I also checked with SAP Theme editor and could not able to download it from SDN.Please help me in a better way of applying basic themes

to web dynpro application(an open CSS editor/SAP theme editor)

Thanks

Vaishnavi.
