dhtmlxgrid_pro.css syntax error?

When I added the newest version of dhtmlxgrid to my project the CSS file showed as having syntax errors in my IDE. It displayed three places where an equal sign was used instead of a colon. Line 442 (width=100%), and twice on line 447 (padding-top=3px; padding-bottom=3px). I was curious if there was some reason for this that I’m not familiar with, or if it was just an overlooked error? This is from the latest dhtmlxGrid_v36_pro_131108.zip download.

The mentioned code is not a mistake and it shouldn’t occur an error.
If the issue still occurs for you, pleas,e provide with a complete demo or a demo link, where the issue can be reconstructed.
