It is important to note that all version of Microsoft Internet Explorer limit the number of dynamically loaded style sheets to a total of 31 files. The web client framework uses several style sheets and each cell or plug-in may have dynamically loaded style sheets as well.

An important best practice is to only define one CSS file in your plug-in's configuration file.

To use more than one CSS file in your plug-in, create a CSS file to subsequently load your other CSS files using the @import (file.css) command.
