Hi... Is there anywhere I can grab an uncompressed version of the core css stylesheet "mxui.css". We need to use it as a base to style the product, and this will be done on a box that will have no mendix dev environment, just usual front end tools and developer really needs that base style as just using standalone css with no mxui.css is bringing lots of unwanted effects. LR.
Use a file compressing utility that supports the gz-format to unpack the file (7-zip, gunzip etc)
You can better write some custom css and add the class to the body of the index.html and include the css file in the top of index.html. See doc for customizing Mendix apps;
