try to put this in the header of the code of your dashboard
<dashboard stylesheet="file1.css, file2.css"> -------- </dashboard>
try and let me know if it working
You can do this with a CSS import declaration.
For the sake of this example, assume that the view imports the CSS file "mystyle.css":
<form stylesheet="mystyle.css"> ...
The mystyle.css file then includes CSS import declarations which import other files:
@import url("style1.css"); @import url("style2.css");
Note that the import declarations need to be at the top of your CSS files (before other styling statements).
