How to change Grid's border color ?

Hello

How can i change Grid’s border color as shown on the attached picture?

Best regards
Oli

Please, try to use the following css:

<style> div.gridbox{ border-style:solid; border-width:2px; border-color:red; } </style>

As i’m working with Layout i found the following solution:

Layout[4].cells('c').firstChild.childNodes[1].style.border = "dashed #900 1px";

Thank you
